what is an ac pm motor? Is it a synchronous motor or induction motor? does it run at constant speed at a given frequency or has a slip?what is its construction like? what are its operating principles?
What are its advantages over conventional ac motors? I understand these motors are increasingly becomming popular even in higher kw ratings |

Hello subrao
An AC PM motor is an AC motor that has a permanent magnet in the rotor. I operates at synchronous speed as it has a permanent rotor field. It does not need slip to create this field as does an induction motor. AC PM motors are commonly used in servo applications and are limited in size due to the strenght of the magnet required in the rotor.
