Permanent magnet motors are electric motors that have permanent magnets placed inside or attached to a motor’s rotor instead of windings, as available in an induction motor. Permanent magnet motors are synchronous motors, which means the rotation of the shaft inside a permanent magnet motor is proportional to its current supply frequency. The main advantage of permanent magnet motors compared to induction motors are that the former does not require a feedback sensor to obtain precise speed control. Across the world, there is a rising need for increasing efficiency of electric motors and lowering the size of machines. Permanent magnet motors are more compact, with lower frame size, and are lightweight and more efficient, thereby reducing CO 2 emission in the atmosphere. They also have reduced operational cost than induction motors. All these factors are driving the demand for permanent magnet motors across all manufacturing industries. In 2015, International Electrote...
