There are a myriad of manufacturers for both brush and brushless motors.
Pittman comes readily to mind. Your best bet is to look under motor
manufacturers on www.motioncontrol.com
You might need a little more information about the load though. Motors (both
brush and brushless) are sized based on the move profile (acceleration, peak
velocity, deceleration). You will also need information on your motor supply
voltage and peak current and continuous current that your amplifier can
source to pick the motor with the proper winding (impacts torque constant
and other motor parameters).
