When a DC series motor is connected to AC supply, the power factor will be low because of: Correct Answer High inductance of field and armature circuits

When a DC series motor is connected to AC supply

  • EMF will be induced and motor gets running but not efficient output power
  • The power factor will be low because of a high inductance of field and armature circuits
  • Eddy current losses will be high and hence excessive heating
  • Sparking at the commutator will occur
