Easier said than done, if you don't have a dynamometer.

You can compare a questionable motor to a known good motor by using the same load for each test. You don't necessarily have to know what the numerical value of the load is.

For example, if you have a CIM-powered elevator lift you can measure the lift time for a good motor and a suspect motor (using the exact same throttle command each time), and compare the results.
