Inspection Details

Enter motor tag number, asset ID, location, driven equipment, and service description.
Record the date and time the solo run or bump test was performed.
Enter the names and roles of the person performing the inspection and the responsible technician or supervisor.

Safety Preconditions and Isolation

Confirm the motor was isolated per OSHA 1910.147 and re-energized only for the controlled test window.
Verify guards, barricades, and exclusion zone controls are in place before starting the motor.
Confirm required PPE is worn, including electrical PPE as applicable under the site risk assessment and NFPA 70E.
Confirm the megger, multimeter, vibration meter, and temperature measurement device are calibrated or in current verification status.

Pre-Start Electrical Checks

Record the insulation resistance reading measured before the solo run.
Record the winding resistance value or phase balance result. Use comments to note phase-to-phase comparison and any imbalance.
Confirm all terminations are tight, correctly landed, and equipment grounding is intact.
Verify the shaft, coupling, belt drive, or driven load can rotate without binding before energization.

Solo Run and Rotation Check

Select the observed rotation direction and confirm it matches the required direction of rotation.
Confirm a brief bump test was performed to verify direction and starting behavior before extended no-load operation.
Verify the motor accelerated normally and maintained stable operation during the solo run.
Record whether any unusual sound, rubbing, scraping, or interference was detected during the run.

Operating Measurements

Record the measured running current during the solo run.
Record the vibration reading taken during stable no-load operation.
Record the observed temperature after the motor reaches stable operation.
Confirm the motor, bearings, and terminals did not show abnormal heating during the test.

Deficiencies, Corrective Actions, and Sign-Off

Record any deficiencies, non-conformances, or observations requiring follow-up.
Indicate whether corrective action and a repeat solo run or verification test are required before return to service.
Signature of the person completing the inspection and attesting to the recorded results.
