Which of the following is different component?(a) Commutating poles(b)

1.	Which of the following is different component?(a) Commutating poles(b) Compoles(c) Interpoles(d) Compensating windingThe question was asked by my school principal while I was bunking the class.I need to ask this question from Commutation Process in portion Commutation Process & Excitation Methods of DC Machines
Answer» Correct OPTION is (d) Compensating winding The explanation: Interpoles are located in interpolar REGION in a DC machine, CALLED as interpoles. They raise up the SPEED of voltage commutation. So, they are ALSO called as commutating poles. Compensating winding though used for reducing armature reaction, performs different function compare to interpoles.
