slipringmotor

Can you give a more detailed explanation?

Hello Guest,

Your question is not clear.

A) <"My slipring motor is having brush lifting & shorting device"> = Understand that's OK.

B) <"rotor wdg IR value is ok"> = Understand that's OK.

C) <"shorting device is showing Zero IR value"> =??? Do you mean that the shorting device short-circuits, or do you mean the shorting device is open circuit when you measure the IR of that part?

D) <"why"> = Nobody can properly advise you until you clarify your question - refer (C) above.

E) <"I wan't answer for this"> = You want an answer for this. = Refer (D) above.

When you explain what is needed, perhaps you may be advised properly.

Kind Regards....
