None off the winding wires should have any continuity with the case. If they did, it would mean the motor case would be live when power was applied to the motor.
Have you tried connecting just the motor to the power supply without any capacitors, and starting it off by hand? If the motor is OK, then it should run at almost full but be a bit rough/vibrate.
For starting the motor by hand in this way, I used to get a bit thin rope long enough to wrap it around the motor shaft several times (just wrap it around on itsled so that it self tightens onto the shaft, and will come staright off once unwound). Then I'd pull the rope off as hard as I could to spin the motor, then flick the power on.
When pulling the rope off, make sure you hold it, so that should it not release/get pulled back into the motor, that it'll be pulled out your hand (ie. don't wrap it around your hand/fingers), instead off you getting pulled into the motor. |
