Which of the following torques is NOT associated with a synchronous motor?
Right Answer is:
Type of torque associated with synchronous motor
Synchronous torque or Running Torque: It is the torque that acts on the shaft of a synchronous machine when the rotational speed of the rotor deviates from the synchronous speed and that keeps the machine in synchronism.
Pull-in torque: The amount of torque requires for the synchronous motor to pull into synchronism is called pull-in torque.
Pull-out torque: It is the maximum torque that the synchronous motor can develop without pulling out of step
