In series motor which of the following methods can be used for changing the flux per pole ?
Correct answer: D. Any of the above
- A. Tapped field control
- B. Diverter field control
- C. Series-parallel control
- D. Any of the above
Explanation
A series motor's flux can be controlled by tapping the field winding, diverting part of the current around it, or using series-parallel control. These methods alter the field current or motor current and hence the flux per pole.
