The windings of a three-phase alternator are separated by

Answer: D. 120°

The windings of a three-phase alternator are separated by 120°.

Solution

The windings of a three-phase alternator are separated by 120° in space. And the number of turns on each phase are same. A schematic diagram of a stator of three-phase windings is as shown below.

So, a three-phase EMF is induced in three windings of the alternator which is separated in time by 120°.
