First: This is a high-end DC-Motor but it is noisy. Therefore, it must be installed in an appropriate housing. This is because of the ball-bearings.
I made a TT motor controller with a Maxon motor with more silent sleeve bearings before and the bearings did not last. So this time I decided for ball bearings with their noise-penalty.
The controller has a negative output resistance, which equals the winding resistance of the motor.
Look up the articles of Mark Kelly, Application Note sboa043 or this: https://www.precisionmicrodrives.com/ab-026
REF02 voltage reference, switchable between 33 and 45rpm, both adjustable, OPA548 output device
The speed stability and -regulation are excellent- it is almost impossible to stop the motor with a finger touching the pulley.
Input Voltage ca. 24…40V
I used it in a WellTempered Amadeus and it was an incredible upgrade.
