I am in the middle of making some parts for a project and the motor on my lathe just died, (sort of).
It had been running perfectly. Tried to turn it on after running back after a cut. Got a loud howl. Thats all. Lifted the drive belt and the spindle is free.
Took the motor drive belt off and tried it. Same howl! Tried giving the motor pulley a good spin then hit the power and motor starts and runs perfectly.
I remember replacing the starting capacitor maybe 25 or so years ago but can't remember what the symtoms of the problem were then. (Lucky I can still remember where the lathe is!)
Motor is a simple 3/4 horse 1750rpm frame G56 motor. Furnas reversing switch.
The capacator is a Hi Torque 460/552 mfd.
I went thru my junk motors looking for a similar capacitor to try but find nothing really close.
My question is: Is it likly that the capacitor is shot? Or is the motor itself the problem? When I hand start the motor and then shut it down I can hear something giving a big "click" after it slows down. (Centrfugal switch dropping out,maybe?) Can anyone tell from the above info what the problem is?
Be nice if I only have to change the capacitor as the motor is a pain to get at.
