The other test is to short the motor leads. If that applies the brakes to
the motor, the you have a permanent magnet DC motor. I have found that the
more braking you get this way, the more torque the motor "seems" to have,
especially at low speed.

Are they DCPM (permanent magnet) or wound field motors? How to tell
if they're not marked: put a DC voltmeter on the terminals and spin
the shaft by hand. If the meter jumps, they're DCPM motors.

Ill check. They only have two leads
