>It really sounds like it is the motor and the brushes. As they get worn, the motor will refuse to start or start with reluctance.

Look for a couple of plastic caps in the motor body. If you have them, that usually means the brushes are easily accessible. Order some replacement brushes from the manufacturer of the motor or a place like Grainger or McMaster-Carr.

>I believe that the motor that you have doesn't have brushes, it isn't a universal motor, it has a capacitor, I would probably start there. The tube under the raised area on the side of the motor, remove it and take the capacitor to an electric motor shop and have it checked. A place to start.

>Thanks for your suggestion.

I will definitely have the capacitor checked out before doing something crazy like tearing into the motor.

>That does look like an induction (brushless) motor. I have disassembled and reassembled a few for cleaning, and it isn't all that bad if you don't take them all the way apart. There are 4 long bolts. You take the nuts off and slide out the motor slightly (usually really obvious which way - toward the shaft end). Make sure you aren't binding wires anywhere and slide it out far enough to blow dust out. Slide it back in and bolt it back together. Sometimes you have to clean contacts inside, but that is more commonly needed when it fires up quickly then clicks, dies, spins down and fires up again over and over. Typically capacitors either work or they don't. When they don't, you can start the motor by spinning it by hand (not recommending that nyone do that as a matter of course; it just helps you determine the problem).
