When is motor circuit analysis performed?

Motor circuit analysis is typically performed when the motor is stopped. This is because assessing the motor circuit in a stationary state allows for a detailed examination of its components without the interference of rotational forces or electrical noise that can occur when the motor is operational. During this analysis, technicians can effectively evaluate the integrity of the wiring, the condition of the motor itself, and other critical elements such as insulation resistance and continuity.

Conducting the analysis while the motor is stopped helps uncover potential issues that may not be as discernible when the motor is running, such as shorts or open circuits in the windings. This ensures that any underlying problems can be identified and addressed before they lead to operational failures or safety hazards.

While motor circuit analysis can indeed be beneficial when the motor is running or as part of scheduled maintenance, the most comprehensive assessment occurs in a stationary state, as it allows for a thorough and safe inspection of the system components.
