As the rotor reaches approximately ____% of synchronous speed, the auxiliary start winding is no longer necessary.
A) 25
B) 50
C) 75
D) 95
Synchronous Speed
The speed at which the magnetic field of an AC motor's stator rotates, directly related to the frequency of the supply current and the motor's pole count.
Auxiliary Start
Auxiliary start refers to an additional method or device used to initiate the operation of motors or engines, often used to provide the necessary power or momentum to start under specific conditions.
