Unlike permanent magnet motors, induction motors use two parts: a stationary stator and a rotating rotor. The electric current passes through the stator to produce a rotating magnetic field. This in turn induces a current in the rotor, which creates a second magnetic field. The interaction between these two magnetic fields produces turning torque, causing the rotor shaft to turn.
But the induction motor shaft and the magnetic field do not turn at the same pace. Due to losses in bearings and other elements, the rotor cannot keep up with the field and is usually below the magnetic field synchronous speed by approximately 1-5%. This is called slip. Over time, slip can cause damage to your motor and compressor.
Strong Neodymium Ring Magnets N35, N38, N42, N45, N50 & N52. Neodymium Ring Magnets are widely used in such applications as holding, motors, consumer electronics, medical, sensors and speakers. Due to the high magnetic strength of a Rare Earth Magnet, it has replaced other magnetic materials in order to make a design smaller but achieve the same result.

High-speed permanent magnet motors offer increased energy efficiency compared to conventional asynchronous induction motors. A permanent magnet motor has air-cooled winding heads and water-cooled housing for reliable operation, and extremely low loss lamination grade material in the motor core result in low iron losses. Non-contact magnetic bearings are used to hold the motor shaft in place, so there is less vibration and no friction between the components, resulting in less wear.
