I think its stuffed.
Quite likely, but for the sake of rummaging the random box, I might as well throw a capacitor across it...
Coming soon to a forum near you: a question about motor rewinds.

When you power it up is there any current flow? |
I haven't put a meter to measure, but it hums, so I think that's a yes.

That sounds odd. Normally if the motor is ok & you put power across & hand spin it then it will run.

Maybe the brushes are toast.
Perhaps I should've kept on with the strip down and not got distracted by the lack of capacitors. I'll carry on when I get back... though I was going to do that anyway since I plan to go back with some capacitors...
Ah well...

That convinced me that it wasn't (just) the capacitors and knocked it well down the list of things to do.
It just found itself at the top again and I've pulled it apart to find that it definitely isn't the brushes: it's another induction motor.
Part of one of the coils looks decidedly scorched.
I am not doing well with induction motors: that is three that I've got that aren't working, 2 cooked and one just a puzzle.
I've not yet tried putting 240V across that last one, not having worked out which wire is which... maybe I should just take a guess?

I hate induction motors - the minute you overload 'em they just drop out and sit there burning varnish ! It's as though they go into a sulk and commit suicide !
Once motors start smelling and smoking, it's usually too late to do anything about it I'm afraid
No way you can cut the motor off and replace it with a nice grunty brush motor off an old washing machine I suppose ?

I've got plenty of enamelled wire: for a moment I was trying to persuade myself that I could pull it apart and rewind it... I was not convinced.
The original plan was to put an engine on it... Not sure yet how practical that idea is.
