If you have voltage then probably the circuit breaker -- or maybe the brushes have worn too small to make contact. IIRC, the brushes have bronze springs behind them which could have overheated and lost strength. There is a slim chance the ground has been lost if the screws holding the motor assy together have loosened.

The breaker is located on the brush support plate but does require the motor to be removed and taken apart to access. CB is in the ground side and that connection is made by brass plates on either side of the support being compressed between cast areas on the halves of the motor. Too much current causes the bimetal strip to heat and bend opening the contact and disconnecting the brush and motor from ground. If undamaged, it should reset when the motor has cooled.
