Is there an OEM manual for this equipment?

you have 4 pole, 2 pole from running and 2 pole from starting. connect 1 pole from running and 1 pole from starting and neutral. anther 1 pole of running connect with phase. now connect 1 pole from starting and capacitor. other pole of capacitor connect with phase. if the motor running anti clock ways then just inter change the starting pole each other. subha

Thanks, as i said that the Running winding has 4 sets BUT the starting winding has two sets only. The motor is 1500RPM ie 4pole. Single phase 220volts with permnent cap of 40mf 350volts.There is no centrifugal switch to cut off the starting winding. So the starting winding is in the circuit always.
