Hi everyone,
I am a mechanic with some basic electrical background knowledge but not enough for this small project.

I have just acquired a new three phase motor without capacitor. It has four wires going into the windings, black, red, blue and yellow.

To this motor I need to connect a forward/reverse switch with off position in the middle.

My question is of course, how do I go about doing this? Some easy to follow basic instructions would be very much appreciated.
