There are many kinds of electric motors but in general they have some similar parts.Each motor has a stator, which may be a permanent magnet (as shown in the 'universal motor' above) or wound insulted wires (an electromagnet like in the photo above-right).AC electric motors use a secondary and primary winding (magnet), the primary is attached to AC grid power (or directly to a generator) and is energized.

The rotor sits the middle (most of the time), and is subject to the magnetic field created by the stator.

The rotor rotates as its poles are attracted and repelled by the poles in the stator. This video covers a brushless DC motor where the rotor is on the outside, in other motors the same principle is in reverse, with the electromagnets on the outside.

Read about generators and dynamos here Electric motors can be powered by alternating (AC) current or direct current (DC).

DC motors were developed first and have certain advantages and disadvantages.

They are used to drive pumps, fans, compressors, mixers, agitators, mills, conveyors, crushers, machine tools, cranes, etc, etc.

It is not surprising to find that this type of electric motor is so popular, when one considers its simplicity, reliability and low cost.

These motors can be operated either directly from the mains or from adjustable variable frequency drives.

In modern industrialized countries, more than half the total electrical energy used in those countries is converted to mechanical energy through AC induction motors.

115, 208/230, 400/460 VAC-50/60 Hz 1ph and 3ph input.

For industrial and mining applications, 3-phase AC induction motors are the prime movers for the vast majority of machines.
