Section 3 Maintenance & Troubleshooting
WARNING:
UL rated motors must only be serviced by authorized
Baldor Service Centers if these motors are to be returned
to a flammable and/or explosive atmosphere.
General Inspection
Inspect the motor at regular intervals, approximately every 500
hours of operation or every 3 months, whichever occurs first.
Keep the motor clean and the ventilation openings clear. The
following steps should be performed at each inspection:
WARNING:
Do not touch electrical connections before you first
ensure that power has been disconnected. Electrical
shock can cause serious or fatal injury. Only qualified
personnel should attempt the installation, operation and
maintenance of this equipment.
1.
1.
Check that the motor is clean. Check that the interior and exterior of the motor is free
of dirt, oil, grease, water, etc. Oily vapor, paper pulp, textile lint, etc. can accumulate and block motor
ventilation. If the motor is not properly ventilated, overheating can occur and cause early motor
failure.
2.
2.
Use a “Megger” periodically to ensure that the integrity of the winding insulation has
been maintained. Record the Megger readings. Immediately investigate any significant drop in
insulation resistance.
3.
3.
Check all electrical connectors to be sure that they are tight.
