Electric Motors

There are two fundamental types of AC motor depending on the type of rotor used:

• The synchronous motor, which rotates exactly at the supply frequency or a submultiple of the supply frequency, and;
• The induction motor, which turns slightly slower, and typically (though not necessarily always) takes the form of the squirrel cage motor.
