Service Note:

It is crucial to wait at least 3 minutes before attempting to restart a motor after it has been running. This 3-minute cool-down period allows the motor to dissipate heat and prevents potential damage to motor windings. Attempting to restart a motor in less than 3 minutes will often result in a motor "hum" and failure to start. This occurs because the motor's components are still too hot, and the motor may not have enough torque to overcome the residual heat and start turning.

The specific cool-down time required for a motor will vary depending on its size, type, and operating conditions. It's important to consult the motor's documentation or the manufacturer's recommendations for the appropriate cool-down period. However, the 3-minute rule is a good general guideline to follow.

Always follow the manufacturer's guidelines for cool-down periods and other maintenance procedures to ensure the safe and efficient operation of your motor.
