How To Tell If Your Electric Motor Is Running Hot
Gauging temperatures by touch is never recommended, because depending on the motor, or application, proper or normal operating temperatures may be way above what could be considered safe to touch. Measuring the temperature at the surface of the motor is not a useful indicator of the temperature of the windings or bearings.
