5 Questions
Explain the use of over excited synchronous motor in power systems.
The over excited synchronous motor is used as a synchronous condenser to improve the power factor in power systems.
What are the advantages of a synchronous motor in industrial applications?
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.
How is the field of a synchronous machine excited?
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.
What is the constructional difference between synchronous motor and synchronous generator?
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.
Why must the speed remain constant in a synchronous generator?
The speed must remain constant in a synchronous generator to ensure that the frequency of the output does not vary.
