Making Motor Maintenance and Replacement Easier

making-motor-maintenance-and-replacement-easierSometimes, it’s hard to see around a given motor. One solution is to use portable lights or just a flashlight. A better solution is to install fixed lighting, if practical for that location. Make sure you light up the motor nameplate, the weatherhead, the motor mounting area (to make it easier to read a torque wrench), and the motor coupling.

If the motor is in a remote location, such as a pumphouse, create a maintenance cabinet that includes the following:

  • Vibration tester
  • Rotation tester
  • DMM
  • Infra-red gun
  • Appropriate PPE per NFPA 70E
  • Spare motor overloads (e.g., thermal strips)
  • Spare fuses
  • Three-ring or similar binder that includes drawings, motor specifications, variable speed drive information, motor starter information, and maintenance procedures

Make someone personally responsible for maintaining this cabinet. This person changes batteries in the test equipment, restocks fuses and motor overloads, and inspects the PPE.

A similar cabinet near any critical motor is a good idea, if space permits. If space does not permit, consider setting aside space in your maintenance shop for some emergency carts dedicated to specific critical equipment. When the critical equipment goes down, the response team can roll immediately instead of spending 20 minutes gathering needed items.

With critical motors, consider the following modifications:

  • Bearing temperature sensors with local readout and/or integration into the network
  • Supply voltage monitoring, with alarming for excess voltage imbalance

Vibration monitoring, with alarming for excess vibration.
