What action is typically taken if voltages are outside the specified percentage of the motor rating?

When voltages are found to be outside the specified percentage of the motor rating, adjusting the voltage supply is typically the required action. Motors are designed to operate efficiently within a certain voltage range, as specified by the manufacturer. If the voltage is too high or too low, it can lead to inefficiencies, overheating, or even damage to the motor.

By adjusting the voltage supply, technicians can ensure that the motor receives the appropriate voltage necessary for optimal performance. This step helps to prevent potential malfunctions and prolongs the motor's life, ensuring it operates within its designed parameters.

While other actions such as inspection or replacement may be relevant in some scenarios, the immediate and correct response to improper voltage conditions is to rectify the voltage supply before considering more extreme measures. Adjusting the voltage helps maintain the system's overall functionality and reliability.
