The synchronous motor is not inherently self-starting because________?
Aa rotating magnetic field does not have enough poles
Bthe force required to accelerate the rotor to the synchronous speed in an instant is absent
Cthe rotating magnetic field is produced by only 50 Hz frequency currents
Dthe starting device to accelerate the rotor to near synchronous speed is absent
Correct answer
B. the force required to accelerate the rotor to the synchronous speed in an instant is absent
Explanation
The correct answer is the force required to accelerate the rotor to the synchronous speed in an instant is absent.
