Electrical Engineering XYZ MCQ
Inter pole winding is connected in:
- Series with main poles
- Parallel with main poles
- Series with armature
- Parallel with armature
Correct answer: 3. Series with armature
Explanation: Interpoles, also known as commutating poles or commutating winding, are additional field windings placed between the main poles of a DC machine. These interpoles serve the purpose of compensating for armature reaction, which is the distortion of the magnetic field caused by the armature current.
Connecting the interpoles in series with the armature ensures that the compensating effect is in the same direction as the armature reaction. This series connection helps in minimizing the sparking at the brushes and improves the commutation process in a DC machine.
Therefore, the correct option is:
- Series with armature
