A synchronous motor is one that keeps step with the alterations of an alternating current.

In a synchronous motor the armature reaches the 90 degree position at the exact instant at which the current reverses in the line.

By the use of the synchronous motor-generators the lighting circuits are protected from these pressure variations.

The principle of the synchronous motor is illustrated in Fig. 447.

In practice the synchronous motor has a number of pairs of field poles.
