FAQS about Permanent Magnet Motors in the Textile Industry
How long is the service life of permanent magnet motors in textile applications?
The service life of permanent magnet motors in the textile industry is affected by various factors. Generally speaking, if the operating environment is suitable and maintenance is proper, its service life can reach 10 – 15 years.
First, the operating environment is crucial. If the humidity, temperature in the textile workshop are moderate and the dust is less, the risk of erosion or demagnetization of the internal electronic components and permanent magnets of the motor is low.
Conversely, a humid environment may cause rusting of the internal components of the motor, high temperature will accelerate the demagnetization of the permanent magnets, and a dusty environment is likely to block the heat dissipation of the motor, all of which may shorten the motor’s life.
Second, the load situation also has an impact. If the motor operates in an overloaded state for a long time, the windings will heat up, accelerating the aging of the insulation and reducing the service life. While operating within the normal load range, the motor can maintain a good condition.
Third, maintenance is of vital importance.
Regularly cleaning and inspecting the motor and promptly replacing worn – out parts can effectively extend its service life.
For example, regularly cleaning the dust on the surface and inside of the motor to ensure the smooth heat – dissipation channels; regularly checking the wiring terminals of the motor to prevent looseness from causing failures.
