Similar to a car, a Baldor motor should be checked every three months or every 500 hours, whichever comes first. If you notice any problems, then check the Baldor website. They’ve compiled a handy chart of common problems and their solutions. For example, a strange noise may be caused by material trapped in the air gap or ventilation opening.
Baldor motors are particularly vulnerable to high ambient temperatures, as well as dirty working conditions. Be sure to check the maximum operating temperature and duty cycle of each Baldor motor. This information is usually found on the motor’s name plate.
