Q.

The synchronous motor meets increase in load by taking more armature current as 

  • AThe rotor pole falls back relative to the stator pole causing an increase in motor current
  • BThe back emf decreases causing an increase in motor current
  • CRotating field is strengthened causing an increase in motor current
  • DNone of the above 
Correct Answer : (A)

The rotor pole falls back relative to the stator pole causing an increase in motor current

Hints :

The synchronous motor meets increase in load by taking more armature current as the rotor pole falls back relative to the stator pole causing an increase in motor current.
