One thing to remember with bench supplies feeding motors is that the supply needs to be able to function with the stall current of the motor. CIM motors have a stall current of 129 amps, something too high for most common 25 amp bench supplies to handle. Many, regulated supplies will go into current limit or will trip off during that kind of load.
Switching power supplies may also radiate high frequency energy that could interfere with the operation of digital devices if some preventive measures are not taken. That is why all computers use extensive LC filtering on power supplies and peripherals.
