The motor has no markings. It has for wires coming out. The shaft is 3/8". It is about 7" long and 3" dia. There is a 3 hole bolt circle. Does anyone have any leads? Thanks

It appears to have brushes, if so it makes it DC, probably Red & Blue aramture.
The yellow could be a tach, there looks like a rear cover.
Put a dc voltmeter on the red/blue and spin the shaft, if voltage out then this could be the armature, but the tach also puts out a voltage so this together with a lower resistance for the armature should confirm it.
See if the rear cover comes off to check further.
If the two yellow show 0 resistance, then these most likely are a thermal sensor switch.

That thing on the back might be an electric brake.
