Central Vac trouble shooting

My beam “Classic clean stream” central vacuum suddenly stopped working. It is approximately 15 years old. I have replaced the control board about five years ago d/t lightning damage. The motor seems completely dead now. I removed the motor and hooked it up directly to 120 V AC. No response. I assume I can test the motor in this fashion without a control board, correct?? If this is correct, how do I troubleshoot this further? How do I know whether the brushes are worn? (I figured that if it were the brushes, that it would at least work intermittently?)

My other issue is, it is not obvious how to remove the brushes from this motor. This comes from a Beam Classic “Clean stream” vac. The only identifying marks on the motor is a sticker with SA 660-007 KB02. BP-11 space ECP 120 V AC 60 Hz

Any help is much appreciated!!

 

Beam Classic “Clean stream” is just a trade line. What is the model number off the tag ?
The BP-11 ECP 120v series motor looks to be an Electrolux unit.
Replacement motor

The brushes are usually easy to get to but when replacing them the commutator may need to be cleaned up on a lath. The commutator is the part on the motor where the brushes ride. It can get completely rough and blackened.
