MOTORS. AC Brushless Motors. AC brushless motors use the induction of a rotating magnetic field in the stator to turn the rotor and stator at the same rate. Like DC motors, these are permanent-magnet synchronous motors, or PMSMs, that rely upon magnets built into the rotor.

What is a single-phase motor? A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy.

As the power requirements of single load systems are usually small, all our homes, offices are supplied with a single–phase A.C. supply only.

We use the single-phase power system more widely than three phase system for domestic purposes, commercial purposes and some extent in industrial uses.

AC induction machines are popular due to their simplicity, reliability and direct operation from an AC line voltage. ACIMs are asynchronous machines and always have a lower mechanical rotor speed than the power line frequency.

An induction motor or 3 phase induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding
