Problem there is cooling the motor: the pump motors get a lot of power from a small volume because they rely on the pumped media to provide cooling - run one at full load in air and watch for the magic smoke!

I am in the design stage of an abrasive tool, and I would like to use the motor/shaft as the driving mech., but I need as much clearance as possible off the face of the motor.
Induction machine, or universal? Universal machines can get a lot of power out of a very small volume because they run at very high speeds. They have a lot of disadvantages: relatively short life, arcing, noisy to name some of them. Do these matter in your application? The majority of hand-held power tools use universal motors.
