[QUOTE="waigy, post: 495259, member: 32627"] Brook Crompton Parkinson single phase PD90S (from the 70s) 240v 11A 2850rpm 50hz I'm using it for polishing metal with a tapered spindle adapter and buffing wheels. I've got 2 questions. 1. (This photo was taken with all the wiring in its original position.) I've managed to reverse the motor rotation by swapping the two black wires that are behind the copper connector, but after a few quick trials it is constantly blowing fuses. Can you confirm that I have changed the correct wires to reverse the rotation? 2. The capacitor starts the motor with a massive jolt which forces the buffing wheel so far onto the tapered spindle that I need large pliers to loosen the buffing wheel. If I fitted a smaller capacitor would it start more gently or is it possible to remove the capacitor and start the motor by hand by rotating the buffing wheel? The white arrows point to the three wires that go inside to the motor. [IMG]https://talk.electricianforum.co.uk/uploads/imageproxy/P1010335.jpg.d9d14e544c04631041db74e360158026.jpg[/IMG] [/QUOTE]
