A PM motor is an ac motor that uses magnets imbedded into or attached to the surface of the motor’s rotor. The magnets are used to generate a constant motor flux instead of requiring the stator field to generate one by linking to the rotor, as is the case with an induction motor. A fourth motor known as a line-start … See more An ac induction machine (IM) also is commonly referred to as an ac motor. A rotating field is generated by the stator winding. The rotating field induces a current in the rotor bars. The current generation requires a … See more To understand the operation of PM motors, it is important to first understand the concepts of magnetic flux, flux linkage, and magnetic flux. Flux: The flow of current through a conductor creates a magnetic field. Flux … See more An electric machine’s torque can be broken down into two components: magnetic torque and reluctance torque. Reluctance torque is the “force acting on the magnetic material … See more Back emf is short for back electromotive force, but also known as the counter-electromotive force.
