The compensating winding in the conductively compensated DC series motor is provided as

Right Answer is:

Parallel with armature winding

SOLUTION

  • The cross-magnetizing effect of armature reaction may cause trouble in d.c. machines subjected to large fluctuations in load.
  • In order to neutralize the cross magnetizing effect of armature reaction, a compensating winding is used.
  • The compensating windings consist of a series of coils embedded in slots in the pole faces. These coils are connected in series with the armature. The series-connected compensating windings produce a magnetic field, which varies directly with armature current.
  • Therefore this induced emf developed in compensating winding acts opposite to armature emf and as a result commutation increases.
