sorry i did forget to add that i automatically switch the capacitor off after about 5 seconds when the mototr is up to speed.
The 3 phase motor appears to be quite happy single phasing and runs a lot smoother than a 1Ø motor (less noisy) OK i know that i have not the full 5 HP available but that doesn't matter. it serves my purpose of a 1Ø to 3Ø supply in my workshop at home.
