Repulsion Start Advice

[billyfender]

Well, i went up to the workshop today, and had a good look. First i grabbed the old starter, it looks a bit beyond it, i dont think, without alot of work anyway, its worth building it back up.
Heres what the faceplate looks like

And behind the faceplate

Everything is very rusty, and would need re-winding with new coated wire.

Anyway, the motor itself. I dont think it is switching when it is up to full speed, im not exactly sure what is supposed to happen!
I started it up under the load of the saw and belts etc, and it doesnt change pitch or anything when up to speed. I removed the belts to see whther the load of the saw was holding the motor back, and it wasnt achieving full speed. When i turned it on no load, it got up to speed and then half a second after, it started to accelerate alot, and it was constantly accelerating, so i switched it off in fear of it breaking. When it was speeding up under no load, the brushes were sparking blue very brightly!

Before it was started, i cleaned the surface up a little, and wiggled the brushes to ensure they are free to move.

Heres what it looks like inside, as much as i could get with my camera anyway.

And finally, behind the connection plate, after blowing the sawdust out :/

The brushes have loads of life left in them, but im not sure whether i should take the motor off and strip it right down to clean it out entirely, and see whether the shorting ring is moving?

Cheers guys!

Looking at photo 5 I would say this motor is connected for 110v.Try connecting the motor as shown in the diagram for the higher voltage and see what happens

The ideal would be push button start and stop with auto ramp up. £££££££

£1 x !7 LOL :stuart:
