Top 10 Permanent Magnet Synchronous Motor Manufacturers in China

China has a broad range of permanent magnet synchronous motor suppliers serving industrial pumps, fans, compressors, production machinery and specialized drive systems. However, the presence of a motor manufacturer in China does not establish that its products fit a particular duty cycle, rated power, voltage, speed or control system.

This guide examines ten China based companies with published permanent magnet motor products or documented systems that use PMSM technology. It compares specific product families, identifies where public information is incomplete and explains how industrial buyers can verify suitability before requesting quotations or ordering samples.

The companies form a research shortlist, not an independently tested ranking of product performance, price or market share. Manufacturer specifications cited below are company published information, not third party measurements. Product availability and suitability must be confirmed for the selected model.

China PMSM Manufacturers at a Glance

To help buyers compare PMSM manufacturers in China more effectively, this overview highlights their documented motor products, technical specializations and industrial applications.

The selection criteria below explain how these companies were evaluated and what buyers should consider when interpreting the comparison.

How These Manufacturers Were Selected?

Each entry was evaluated for an identifiable permanent magnet motor series or documented PMSM application, an accessible primary product source and a plausible industrial buyer use case. Companies differ substantially in scope.

Some publish standalone industrial motors, one demonstrates PMSM technology within integrated refrigeration equipment, and another specializes in permanent magnet servo systems. These categories should not be treated as interchangeable.

The order of appearance does not represent a quality score. Published power figures are series level ranges and do not establish that every possible speed, voltage, cooling or mounting combination is available.

Where a model specific value cannot be confirmed from the referenced source, the table states that the buyer must obtain it from the manufacturer.

Permanent Magnet Synchronous Motor Manufacturers in China

The profiles below explain what is supported by available product information and which additional questions determine practical suitability. They intentionally avoid generic claims that any one company is the best manufacturer or provides the lowest price.

Zhuji Hiest Motor Co., Ltd.

Zhuji Hiest Motor Co., Ltd. develops permanent magnet motor and magnetic drive products through the JYMAGTECH brand. Its published portfolio describes self starting PMSMs, variable frequency PMSMs, integrated motor and control solutions and custom permanent magnet projects.

The public product navigation also includes three phase, water cooled, rare earth and explosion proof permanent magnet motor categories.

For a buyer, the strongest starting evidence is the relevant motor model, technical drawing and matched inverter requirements.

The public website describes several product types but individual specifications should be reviewed before being included in a cross supplier performance calculation.

Ask the company to confirm rated power, continuous torque, operating speed range, voltage, mounting interface, cooling conditions and the test documents available for the proposed configuration.

Company information is published on the Zhuji Hiest company page. The three phase PMSM product page provides an initial product reference.

Hiest Motor is the publisher of this comparison. Inclusion of Zhuji Hiest in this list is disclosed and should not be interpreted as independent endorsement.

Shanghai Electric Machinery

Shanghai Electric Machinery publishes distinct permanent magnet motor series within a broader industrial motor portfolio. Its SDPM5 series is identified as a variable frequency permanent magnet three phase synchronous motor with frame sizes from H80 to H355, a published power range of 0.37 to 315 kW and rated voltage options of 380 V and 660 V. Its publicly described rated speed configurations include 1000, 1500 and 3000 rpm.

This series provides a documented starting point for industrial drive applications including fans, pumps, compressors and conveyors. It does not establish the suitability of the wider Shanghai Electric group for every PMSM requirement.

Confirm the specific manufacturing entity, speed and torque performance of the proposed model, VFD compatibility and mechanical mounting dimensions.

Primary source is the Shanghai Electric SDPM5 product page.

Wolong Electric Group Co., Ltd.

Wolong publishes the WEPM variable frequency permanent magnet synchronous motor series for industrial applications. Its official technical page lists rated power from 0.18 to 315 kW, rated voltage up to 690 V and typical rated speeds of 1000, 1500 and 3000 rpm. It also lists IP55 protection and IC411 or IC416 cooling arrangements, with applications including pumps, fans, air compressors and machinery.

The manufacturer describes IE4 and IE5 efficiency levels for the series. That is a published classification claim, not an independent confirmation that every model attains the same level under every operating condition. A buyer should identify the actual motor and applicable efficiency test method, then request torque, thermal and inverter documentation for the intended load.

Primary source is Wolong WEPM series specifications.

Jiangsu Dazhong Electric Motor Co., Ltd.

Jiangsu Dazhong publishes the TYCPX low speed direct drive permanent magnet synchronous motor series. The manufacturer lists frame sizes H355 to H560, rated power from 160 to 1600 kW and voltage options of 3000 V, 6000 V and 10000 V. The listed operating contexts include fans, compressors, pumps and equipment in heavy industrial environments.

This is not a direct substitute for a compact low voltage PMSM. A direct drive project must establish the actual output shaft speed and continuous torque, and assess mechanical interface, cooling, VFD configuration and site electrical protection. The product page also lists explosion protection variants, but procurement for a hazardous location requires certificates and markings applicable to the exact configuration and destination.

Primary source is the Jiangsu Dazhong TYCPX product page.

Gree Electric Appliances Inc.

Gree has disclosed the use of high voltage permanent magnet synchronous motor technology in integrated centrifugal chiller equipment. Its corporate report on a refrigeration product launch describes a 10 kV high speed permanent magnet motor within a direct drive centrifugal chiller system.

That source supports an integrated HVAC application, but it does not establish a general catalogue of standalone industrial PMSMs available for separate purchase. Gree is therefore most relevant to research into complete refrigeration drive systems. A purchaser seeking a standalone motor should first confirm separate supply availability, control electronics, installation interfaces and after sales documentation.

Primary source is the Gree refrigeration technology announcement.

Jiangsu Huasheng Motors Group

Jiangsu Huasheng publishes a TY series of three phase permanent magnet synchronous motors. The manufacturer associates its permanent magnet motors with machinery, fans, pumps, textile equipment, chemical industry, compressors and other industrial applications. Its published product description also discusses direct drive possibilities and variable speed arrangements.

Because the referenced product page does not provide a complete publicly readable model table for every project configuration, buyers should not infer a precise available power or voltage range from the broader company portfolio. Request the actual TY series catalogue, motor data sheet, cooling specification, shaft drawing and controller information before comparing this range numerically with other suppliers.

Primary source is the Jiangsu Huasheng TY product page.

Xi’an SIMO Motor

SIMO publishes permanent magnet synchronous motor products described for industrial direct drive and variable frequency operation. Its product material discusses applications including industrial pumps, compressors, conveyors, mills and other mechanical loads, and distinguishes configurations intended to remove a conventional intermediate gearbox.

A direct drive redesign should compare the output requirements of the complete machine rather than rated motor power alone. Confirm torque at operating speed, starting requirements, vibration, bearing loads, installation dimensions, converter setup and the scope of any proposed customization. The product page includes different descriptions and numerical tables, so exact model details should be confirmed from a current technical drawing or signed specification rather than inferred from the general overview.

Primary source is the SIMO permanent magnet motor product page.

Anhui Wannan Electric Machine Co., Ltd.

Anhui Wannan publishes the TYCP three phase variable frequency permanent magnet synchronous motor series. Its product page reports frame sizes from 80 to 355, rated power from 0.55 to 375 kW and nominal voltage of 380 V. The page associates this range with pumps, fans, conveyors and industrial machinery. It also names IC411 and IC416 cooling variants for certain configurations.

The same product page displays different enclosure protection values in separate descriptions. This makes a model specific data sheet particularly important before recording an IP rating in a formal comparison. For a motor replacement project, ask about flange and shaft compatibility, cooling at lower operating speeds, inverter settings and the actual performance curve.

Primary source is Wannan TYCP series specifications.

Huai’an Jemec Machinery Co., Ltd.

Jemec lists a JPM permanent magnet variable frequency synchronous motor series with published frame sizes from 80 to 560 and a family output range from 0.55 to 1000 kW. The company also lists a voltage range below 1000 V, a broad speed envelope and various cooling and protection options. These are portfolio level figures rather than evidence that every combination can be purchased as a standard motor.

An industrial buyer should request the model list compatible with the required power, continuous torque and speed, then verify the cooling method, site voltage, installation arrangement and corresponding protection grade. Performance and efficiency claims should be tied to a tested model and its stated measurement conditions.

Primary source is Jemec JPM product specification.

Inovance

Inovance publishes the MV21 low voltage three phase permanent magnet servo motor series for industrial control applications. Its product page and user documentation describe flange and foot mounting options, controlled industrial motion and associated drive selection. The user guide describes a published series power range of 4 to 90 kW, with speed classes of 1000, 1500 and 2000 rpm.

This is a relevant option for hydraulic systems and machines requiring an integrated motor and drive design. It should not be presented as equivalent to a conventional general purpose PMSM unless the application requirements support that substitution. Verify drive compatibility, encoder feedback, response, thermal limits and commissioning requirements for the exact model.

Primary sources are the Inovance MV21 series page and its associated model documentation.

For work in a mining or potentially explosive atmosphere, do not rely on general product descriptions, an ordinary CE statement or a certificate from another motor series. The applicable protection requirements and approval scope must match the product, installation and destination.

Which Hiest Motor Product Fits Your Application?

Hiest Motor offers several permanent magnet synchronous motor configurations for different industrial operating conditions.

The right choice depends on the required torque and speed, inverter configuration, installation environment and cooling method.

The following table connects the published Hiest Motor product families with relevant application requirements. Each recommendation is a starting point for technical evaluation rather than a guarantee of compatibility.

Application	Critical operating variables	Technical evidence to verify	Hiest Motor product options
Pumps and fans	Operating duty points, speed range, load variation and part load efficiency	Motor and inverter compatibility, performance at representative duty points and thermal data	Hiest Motor three phase rare earth PMSM for pump and fan duties. Hiest Motor TJY series PMSM can also be evaluated where variable speed control is required.
Air compressors	Continuous torque, compressor duty cycle, running speed and cooling conditions	Torque and speed curves, temperature rise test conditions and mechanical interface dimensions	Hiest Motor three phase rare earth PMSM. The published product description lists compressors among its potential applications, subject to model and drive verification.
Textile and industrial machinery	Speed regulation, operating hours, load changes and required shaft torque	Operating speed range, compatible inverter parameters, mounting dimensions and efficiency data	Hiest Motor TJY variable frequency PMSM or Hiest Motor rare earth PMSM, depending on the equipment and control requirements.
Low speed and high torque machinery	Continuous low speed torque, shaft loading, duty cycle and cooling	Torque speed curve, bearing load limits and feasibility of gearless operation	Hiest Motor rare earth PMSM as an engineering evaluation option. The product page describes low speed, high torque designs, but direct drive suitability must be confirmed for the specified model.
High temperature or restricted ventilation environments	Ambient temperature, heat rejection, coolant availability and continuous loading	Cooling system requirements, thermal performance, connection details and ingress protection	Hiest Motor three phase water cooled PMSM. Its published catalogue includes TJY water cooled configurations; the cooling arrangement and allowable environment require model specific confirmation.
Chemical plants and potentially explosive environments	Gas or dust classification, explosion protection marking, ambient temperature and load profile	Current explosion protection documents for the exact series, nameplate marking and destination requirements	Hiest Motor three phase explosion proof PMSM. Verify that the exact offered motor and its certificate scope match the installation; a general product claim is not sufficient.

For a specific published product example, Hiest Motor lists the water cooled model TJY-132-1000-15 with rated output of 15 kW, rated voltage of 380 V, rated speed of 1000 rpm and torque of 143 Nm.

These are manufacturer published catalogue values, not independent test results. Buyers should obtain the current drawing, drive requirements and model specific performance report before selection.

For hazardous environments, Hiest Motor describes the TBYC explosion proof series and provides an explosion protection marking on its product page.

Final acceptance must be based on the exact offered model, valid certification, location classification and destination requirements. Standard industrial PMSM models should not be assumed suitable for explosive atmospheres.

How to Evaluate a PMSM Manufacturer Before Shortlisting?

Once the application and target duty are clear, compare every candidate using the same technical and commercial questions. A supplier that provides precise data but does not meet the machine duty should be excluded before evaluating price.

Motor Specifications and Drive Compatibility

• Define rated power in kW, continuous torque in Nm, peak torque where relevant, nominal speed and permitted operating speed range.
• Document the supply voltage, inverter or drive model, control method and any feedback requirement.
• Provide the machine load profile, starting frequency, duty cycle and expected hours of operation.
• Confirm mounting, shaft geometry, cooling circuit or airflow, enclosure rating and permissible ambient conditions.
• Compare efficiency only where the motor definitions, operating points and test methods are comparable.

A nominal 15 kW motor can be unsuitable if continuous low speed operation exceeds its cooling capacity or if the available drive cannot achieve the required torque response. For a more detailed sizing discussion, consult the PMSM selection guide.

Manufacturing and Customization Capabilities

Ask whether a requested motor is an existing catalogue configuration, a minor manufacturing variant or a new engineering project. Clarify changes to windings, shaft geometry, flanges, rotor materials, enclosure, cooling and drive matching. For applications with elevated temperature or corrosion exposure, the proposed permanent magnet material and its protection should be confirmed against the operating conditions. NdFeB and SmCo are material families, not interchangeable guarantees of motor performance.

Customization capability should be demonstrated through engineering drawings, samples or prior validated configurations where available. A marketing statement that a supplier offers OEM development is not equivalent to proof that the proposed thermal, mechanical or electromagnetic design has been verified.

Quality Testing and Standards Evidence

A performance claim needs a stated measurement method and operating condition. Compare efficiency and temperature rise at relevant load points, and request evidence for insulation performance, vibration, mechanical integrity and protection requirements. Where appropriate, review the scope of IEC TS 60034-30-2 for variable speed AC motor efficiency classes. It does not apply automatically to every motor or every integrated drive system.

Company level management certification, a product conformity statement and a motor efficiency test report answer different questions. Confirm the legal manufacturer named on each document, the exact motor series covered, the applicable market and the document validity. Published claims of IE4 or IE5 should be checked against the correct standards and rated conditions.

Lead Time, Technical Support and Commercial Conditions

Request a written distinction between standard build lead time, modified models, engineering samples and production orders. Compare warranty conditions, included inverter support, replacement parts, agreed testing, packaging requirements and delivery terms. A lower quoted motor price is not necessarily a lower total project cost if integration, commissioning or missing documentation adds expense.

How to Verify PMSM Specifications and Sample Testing?

The purpose of sample testing is to establish whether a specific motor and drive configuration can perform the intended machine duty. Testing should be planned before an order is placed so that results can be compared with an agreed acceptance basis.

Required Performance and Test Data

Verification category	Conditions to confirm	Evidence to request
Electrical and performance	Power, voltage, current, torque, speed and efficiency at representative loads	Model data sheet, recorded test values and stated test conditions
Thermal verification	Continuous load, ambient temperature, duty cycle, cooling and winding temperature	Temperature rise or thermal test record with operating conditions
Mechanical verification	Mounting, shaft dimensions, vibration, noise and bearing loading as needed	Approved drawing and relevant mechanical inspection results
Drive compatibility	Starting behavior, low speed torque, feedback and converter settings	Compatible drive information and commissioning parameters
Environment and compliance	Ingress protection, insulation and any hazardous area requirements	Current documents explicitly covering the supplied model

Sample Testing Under Actual Operating Conditions

Run the sample with the intended motor drive or a validated equivalent, the expected mechanical load, representative ambient conditions and the planned duty cycle. Test more than a single rated speed if the machine normally varies speed or torque. For continuous operation, monitor temperature stabilization and any inverter or motor protection events rather than relying on a short no load run.

Acceptance Criteria Before Production

Define pass and fail limits in advance using the real engineering needs of the machine. These could cover continuous torque, temperature rise, permitted vibration, rated current, insulation results, motor protection behavior and dimensional tolerances. The appropriate numerical limits must come from the equipment specification and applicable standards, not from arbitrary values included in a generic supplier article.

If a sample fails, document the symptom, diagnose the likely cause, request corrective action and repeat the relevant test. Do not release a revised configuration for production solely on the basis of a supplier statement that the issue has been solved.

Ordering and Supplier Documentation Requirements

Request quotations against an identical technical scope so that motor differences are not hidden inside the price. Include the engineering parameters, sample acceptance conditions and required documents in one written RFQ.

What to Include in a PMSM RFQ?

• Machine description, existing motor data when applicable and the reason for replacement or new design.
• Rated power, operating speed range, continuous and peak torque, duty cycle and the anticipated load profile.
• Supply voltage, converter arrangement, control mode and feedback requirements.
• Mechanical drawings, mounting arrangement, shaft interface and available installation space.
• Cooling, ambient temperature, altitude, moisture, dust exposure and hazardous area requirements.
• Required technical documents, test records, certificates and sample acceptance conditions.
• Prototype quantity, forecast production volume, destination, packaging and requested delivery window.

How to Compare Offers Using the Same Evidence?

Decision factor	Documents to request	Practical selection rule
Technical fit	Proposed model data sheet and operating curve	Proceed only if continuous machine duty can be supported
System integration	VFD and feedback documentation	Confirm the motor and control system as a complete arrangement
Performance evidence	Test results and stated conditions	Compare values measured under comparable operating points
Manufacturing evidence	Actual supplier and product identity, available samples	Verify the company supplying the exact configuration
Commercial fit	Itemized quote, lead time, warranty and delivery scope	Compare project cost and responsibilities beyond unit price

For industrial buyers reviewing several Chinese suppliers, a useful shortlist is the small group that can document a matching motor, respond to technical questions and agree to a practical verification plan. Incomplete data should remain a request for evidence, not be converted into a claimed advantage or disadvantage.

Conclusion

The right permanent magnet synchronous motor manufacturer in China depends on the specific project. Wolong and Shanghai Electric publish documented variable frequency PMSM ranges for common industrial applications. Dazhong and SIMO offer products relevant to direct drive research. Wannan and Jemec publish additional industrial ranges, while Inovance is especially relevant to motor and control integration. Gree demonstrates permanent magnet technology within an integrated refrigeration system rather than an established standalone motor catalogue.

Begin with the machine duty, compare original product information and verify model level performance before requesting samples or committing to production. A published catalogue range is a useful research starting point, but it is never a substitute for an agreed technical specification and appropriate test evidence.

JYMAGTECH is operated by Zhuji Hiest Motor Co., Ltd., which is included in this comparison. Buyers considering Hiest products may review the three phase permanent magnet synchronous motor range, the water cooled PMSM category and the explosion proof PMSM category.

These product pages provide project starting points, and the applicable specifications and certificates should be confirmed before purchase.

To discuss a particular motor and drive requirement with Zhuji Hiest Motor Co., Ltd., submit your project requirements including power, torque, speed range, voltage, operating environment and expected volume.
