motor unknown
(OP)
Hi, I have to control a gearmotor which doesn't have any tag or spec.I know it's a run capacitor 220 volts.it has five wires coming out of its terminal box. two yellows, two blacks, one red.I have to control it on -off -forward and reverse for a conveyor belt. Can you guys give some guidance about this wiring and define this motor?
thanks
thanks

Get a new motor that suits the application. A single phase motor has a rather low starting torque and conveyors are known to have a high torque demand at start. Chances are that it will not start. Use a VFD and a three-phase induction motor. Dirt cheap it is also.

I connected 1-5 and 4-2 to 220 volts and worked cw.then
I switched 1-2 and 4-5 then work ccw.
The amps reading at 4 and 1 was 2.5 amps.
Note:the motor was unloaded.
also I had some reading on 7 and
ground,about 45 volts. while the motor was running.
