What are the two basic functions of synchronous motor control?

Expert Solution
To determine

Explain the two primary functions of the synchronous motor control.

Explanation of Solution

Two basic functions of the synchronous motor control in starting are as follows:

  1. (1) To start the motor as an induction motor by use of induction motor starting schemes. In this, the motor connects across the supplying line or to the starter output terminals. The starters that are used to start the motor as an induction motor are based on the size of the motor.
  2. (2) Synchronization process of the motor by the DC field (rotor) excitation to bring the motor to the synchronous speed is the second basic function. In starting of the synchronous motor two voltages are required, AC and DC for the stator and the rotor respectively.

Conclusion:

Thus, the two primary functions of synchronous motor control are explained.
