My "Ridgid" brand shop vac stopped working in a puff of white smoke because I was vacuuming bees out of a junk TV set (while wearing a bee suit) and it started to "misty" rain. I thought I'd burned the thing permanent, so never tried to turn it back on.
Disassemble the motor housing and extracted the Motor, disassembled the motor. Very simple, very basic. Visual inspection shows the brushes both look good, no scorching or burning on the stator, it spins freely, the cord ohms good, the switch ohms good and the ONLY thing I can see that might have shut the thing off is a 1 1/2" "something" inside a protective sleeve on the interior windings of the motor. Assume this is a current overdraw protection, or thermistor, or something.
The windings ohm short where they should, and open where they should. I have very basic understanding of how motors work and that's where the question comes in.
I don't want to wire this thing wrong and risk burning it up. I can't remember which wire goes where. I have one constant wire from the AC cord that goes straight to the motor, and the other wire goes through the big, main Power Switch before it also goes straight to the motor.
I have four terminal clips to choose from, and I assume one wire goes on one side and the other wire goes on the other side, but I'm concerned that it matters which one goes where.
One side of this motor has a big letter "N" next to where the brushing clips to the windings, and the other side does not. I assume "N" is for neutral, but is Neutral the switched side, or the common side? (Please correct my terminology, it's been years since I really needed to put this knowledge to use.)
I can post pics if necessary. Hoping this text is descriptive enough to get help. Also hoping that it will work when I put it together, because disassembly and cleaning of the motor housing was a real PITA.
Other questions:
1) I decided not to lubricate anything inside the motor (grease, WD-40, etc...) because it would attract dust and eventually be a drag on the motor. Correct?
2) What's this fabric covered thing spliced into the windings inside the motor? i.e. What's most likely; current overdraw or temperature protection? Both?
I can post pics of all of this. It's right here on my desk next to my elbow. Thanks in advance.
