Compare basic construction of synchronous motor and alternator
Question: Compare basic construction of synchronous motor and alternator
Answer: In terms of construction synchronous motors are identical to salient pole synchronous generator (alternator). The stator of the motor has 3 phase winding, while the rotor has a set of salient poles. The rotor is usually excited by direct current. Slots in the synchronous motor are punched along the circumference of salient poles. They carry a damper winding like in an induction motor. The damper windings are used for starting motor as well.
