INDUSTRIAL ELECTRICAL POWER MAINTENANCE, MOTOR INSTALLATION AND TROUBLE SHOOTING

INTRODUCTION FOR INDUSTRIAL ELECTRICAL POWER MAINTENANCE, MOTOR INSTALLATION AND TROUBLE SHOOTING

The key to minimizing motor problems is scheduled routine inspection and service ensuring your brushes and commutators are included in this regular maintenance. The frequency of routine service varies widely between applications.

Including the motors in the maintenance schedule for the driven machine or general plant equipment is usually sufficient. A motor may require additional or more frequent attention if a breakdown would cause health or safety problems, severe loss of production, damage to expensive equipment or other serious losses.

Written records indicating date, items inspected, service performed and motor condition are important to an effective routine maintenance program. From such records, specific problems in each application can be identified and solved routinely to avoid breakdowns and production losses.

The routine inspection and servicing can generally be done without disconnecting or disassembling the motor.
