An AC motor is an electric motor driven by an alternating current
AC MOTORS
2 TYPES OF AC MOTORS
There are two main types of AC motors depending on the type of rotor used
The first type is the induction motor which runs slightly slower than the supply frequency The magnetic field on the rotor of this motor is
