After testing motor operation, if you find it operating normally, what should you check next?

After confirming that the motor is operating normally, it is crucial to check the mechanical loads on the motor next. This step is important because a motor can run without any electrical faults, yet still be subjected to excessive mechanical loads that could lead to inefficiencies, overheating, or premature failure.

Evaluating the mechanical loads involves checking factors such as the alignment of the motor with the driven equipment, the condition and tension of belts or chains, and whether any obstructions inhibit the motor's normal operation. By ensuring that the mechanical load is within the motor's designed limits, you help maintain optimal performance and prolong the life of the motor.

Addressing the mechanical aspect first ensures that the motor isn't operating under conditions that could cause it to fail despite functioning correctly at the moment of testing. This proactive approach is essential in electrical equipment maintenance and service.
