Electric Motors AC

AC electric motors (alternating current) is a very wide class of electric motors, including single / multiphase, universal, servo, induction, synchronous, and gearmotor types. The magnetic field, generated by ACelectric motors , is produced by an electromagnet powered by the same AC voltage as the motor coil. The coils that produce the magnetic field are traditionally called the "field coils" while the coils and the solid core that rotates is called the "armature". There are many advantages in the use of acmotors aside from the wide availability of AC power. In general, AC motors cost less than DC motors.
