10 Understanding and Caring for Your Linear Motor
Maintenance Anorad linear motors require no maintenance when operated in a relatively
clean environment. For operation in harsh and dirty environments, minimal
cleaning is recommended every 6 months.
Clean the metallic debris and other contaminants from the air gap. To
effectively remove the metal debris use a strip of masking tape. Simply put a
strip of tape in the magnet channel and then remove it.
Keeping the magnet channel clean will prevent witness marks. Witness marks
are caused by metal debris being dragged across the surface of the magnet by
the magnet field of the moving coil. Witness marks have no effect on the
performance of the motor.
Motor Storage Store the motor in a clean, dry, and vibration free environment it should be
kept at relatively constant temperature. The coil resistance measurement
checks explained in this manual should be done at time of storage. If a motor
is stored on the equipment, it should be protected from the weather.
