I could use some quick help on troubleshooting an electric motor. Not sure of the type; maybe some help there too. 120 v guessing 3/4 hp. the windings are on the stator, the rotor is basically a smooth cylinder. No brushes nor centrifugal switch for start. It does have a continuously connected capacitor. about 1-1/2" dia. x 5" tall. The motor is on a floor scrubber. the bottom end cap is also the top of a gear housing. Three weeks ago I ordered a replacement and it arrived yesterday with shipping damage to that bottom end cap. I pulled the old motor apart hoping to just swap out that bottom end cap but I think the seal is a one time press in. I didn't dig too far because if I cant save the seal, I probably can't save it on the new one either. Any idea on where there may be a circlip or whatever that's keeping that end cap on?
The motor lacks power and trips out the thermal overload. The rotor does show blue areas indicating some over heating. No nasty smoke smell on the windings though. I didn't have the correct multi-meter to check the cap , but do you think a bad , but still functioning cap can cause these symptoms?
Sorry, I don't have access to either motor right now. I was hoping the supplier could overnight a replacement. They dropped the ball. I need this up and running by Sunday night so any parts need to be ordered in the morning.
