The maximum speed variation in a 3-phase synchronous motor is
The maximum speed variation in a 3-phase synchronous motor is
Right Answer is:
Zero
SOLUTION
- A synchronous motor runs at synchronous speed or not at all. Its speed is constant at all loads.
- The maximum speed variation in the synchronous motor is zero. The speed of operation remains constant from NO load to FULL load in the motor operating at constant frequency bus bars.
- A synchronous motor runs at one speed only i.e. synchronous speed. Consequently, slip is zero.
