A 3-phase synchronous motor is running clockwise. If the direction of ...
In a synchronous motor, the rotation of the rotor is synchronized with the rotating magnetic field produced by the stator. The direction of rotation is determined by the interaction between the stator field and the rotor field.
Reversing the direction of the field current in a synchronous motor does not affect the synchronization between the stator field and the rotor. The rotor will still rotate in the same direction as before because the reversal of the field current only changes the polarity of the magnetic field produced by the rotor.
Therefore, the motor will continue to run in the same direction even if the direction of the field current is reversed, making option B the correct answer.

A 3-phase synchronous motor is running clockwise. If the direction of ...
Explanation:
Direction of Rotation in a Synchronous Motor:
- In a 3-phase synchronous motor, the direction of rotation is determined by the direction of the magnetic field produced by the rotor.
- The rotor of a synchronous motor follows the rotating magnetic field produced by the stator windings.
Effect of Reversing Field Current:
- When the direction of the field current is reversed in a synchronous motor, the direction of the magnetic field produced by the rotor also reverses.
- Since the rotor follows the rotating magnetic field produced by the stator windings, the rotor will continue to run in the same direction as before.
- This means that the motor will continue to run clockwise if it was running clockwise before reversing the field current.
Therefore, the correct answer is option B: the motor will continue to run in the same direction. Reversing the field current does not change the direction of rotation of a synchronous motor.
