Motor Inspection Procedure After Storage

Motor Inspection Procedure After Storage

Question: After storing my motor for an extended period of time, I am now ready to install it. Is there any specific inspection procedure that must be followed?

Answer: Yes. Following storage, an extensive inspection must be performed on a motor by one of USEM’s authorized service stations. This inspection must include the following elements:

1.) Render an external inspection of the motor to assure the unit is clean, ventilation openings are free of obstructions, and no damage has occurred.

2.) Perform a megger test of motor windings to insure satisfactory insulation resistance.

3.) Rotate the shaft to check for roughness in bearings or interference between rotating and stationary parts.

4.) Perform a bench test on the unit to check for excessive amp. draw, noise, or vibration.

5.) Regrease the motor bearings (as applicable) in accordance with the unit’s operating instruction folder.

6.) USEM’s authorized service station must install a plate/tag indicating the date of inspection. This tag will be considered a new factory date code for warranty purposes.

7.) Make any corrections which inspection shows to be needed.
