Hi Fella's, Thanks Canoeboy I'll try and upload my original sketch now. I had a word with Machine Mart this morning and they want £120 for a new motor, which is pretty well double what you would pay elsewhere for one of similar specification. They don't supply capacitors seperately as they...

Still don't think I am managing to upload  my sketch yet Canoeboy. All I'm seeing is a square box with a cross in it. Could be a pricey job getting hold of a selection of capacitors and trying each one. I will reassemble and refit the motor NozSpark and see what happens if I try it without the...

Tried drawing this as a ladder diagram Technician but I still can't get my head round it. Is not a phase shift also produced by a capacitor in parallel?

Don't know what the original capacitor size was ProDave. It was a long time ago that I replaced it and my long term memory is now almost as bad as my short term memory. It is 440 volt rating, I think it may have been one of Maplin's motor capacitors. The bearings are ball races and are free and...

That's not adding up for me Technician, A - C measures 86 Megohm (70 Meg yeterday) and with capacitor connected it's down to 1 meg. If you reckon that the start winding is between A and C then it will be in parallel with the capacitor. Also if the run winding is between B and D then this would...

Thanks Dave, The capacitor has a plastic case and measures up as 11.85 uF on my multimeter. Do you think it would be worth trying a different value?

I have a 240v single phase motor which seems to have seriously lost power. It is a budget motor fitted to a cement mixer so it is probably 4 pole about 375watt. I have dismantled it and can see no obvious signs of damage or overheating so I made a few measurements with my multimeter and put...

Hi everyone, A little problem with an electric motor promped me to join a forum so I could ask some questions. I trawled around a few and from what I could see TEF was the one that pleased me best. I'm sure I will stay loyal to it. Regards, Happy Harry
