What is the current draw? Single phase or 3 phase? What do you plan to control the relay with? Perhaps a better description of what you are doing will give us better incite to provide answers.

thanks for your kindly reply
its single phase
the motor had a relay that convert the movement from primary winding to secondary ifter it reaches 90 from the max speed
i want to use this motor to drive a water pump

I'm not sure I'm following, Are you talking about the centrifugal switch to drop out the start winding? What does the old "relay" look like? Is it inside the motor?
