Synchronous Motors vs. Induction Motors - What's the ...

Synchronous motors. Synchronous motors cover the bases that induction motors cannot, namely their "asynchronous" nature. Synchronous motors match the output rotational frequency to the input AC frequency, allowing designers to use these motors in precisely timed applications, such as clocks, rolling mills, record players, and more.

Synchronous motor - Wikipedia

The synchronous motor and induction motor are the most widely used types of AC motor. The difference between the two types is that the synchronous motor rotates at a rate locked to the line frequency since it does not rely on current induction to produce the rotor's magnetic field.

Synchronous motor - Wikipedia

A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line ...
