What are Permanent Magnet Motors?
Permanent magnet motors are an advanced motor similar to both induction motors and servo motors in design (more information on these two designs can be found in our articles all about induction motors and servo motors). They are composed of a stator – the outside housing – and a rotor – the moving component connected to the output shaft of the motor. Much like other AC motors, the permanent magnet motor harnesses the physics of electromagnetism to generate torque, and they do this by using permanent magnets (usually rare earth magnets) embedded in their rotor. This design deviates from most other electric motors, where the rotor either generates its own magnetic field via induction or a through the use of DC power source or is simply composed of a ferromagnetic metal. The magnets in a permanent magnet motor, when properly arranged in relation to the stator, can provide speeds equal to the excitation current frequency, and so are considered a synchronous motor (see our related article all about synchronous motors to learn more).
