Synchronous Machines Quiz

The over excited synchronous motor is used as a synchronous condenser to improve the power factor in power systems.

Synchronous motors are widely used in the industry for high-precision applications, as they run at constant speed and have a constant-speed torque characteristic.

The field of a synchronous machine is excited by a direct current obtained from an auxiliary generator, which is mechanically coupled to the shaft of the main machine.

<p>There is no constructional difference between synchronous motor and synchronous generator. Both have a stator with three-phase windings and a rotor with the field winding.</p> Signup and view all the answers
