Understanding Permanent Magnet Motors
What Are Permanent Magnet Motors?
Permanent magnet electric motors are the electric motors that rely on permanent magnets to establish a magnetic field, as opposed to the traditional magnetically enhanced electric motors.
The difference in terms of design has the virtue of allowing the PMMs to be designed expending less space as well as achieving the goal of high efficiency at the same time.
It is noted that the permanent magnets are often built from neodymium materials and they are applied in the form of a compact structure which possesses strong permanent magnetism making these motors suitable for a wide range of applications.
How They Work
The operation of permanent magnet type motors relies on the magnetic fields generated by the rotor and stator interacting.
When the stator winding has an electric current, it develops a magnetic field which circumvolves.
At the same time, the stator winding, the one equipped with strips of coil profile and soft iron, plays a major role in the generation of the working flux which is used to drive that motor.
The flux interacts with the rotor with the permanent magnets attached within it, leading to the rotation of the rotor.
This enables mechanical energy to be generated through the speed torque product framework which can be put to various uses depending on the requirements at hand.
