Maintenance Linear motors require no maintenance when operated in relatively clean
environments. For operation in harsh and dirty environments, we recommend
cleaning every 6 months.
Clean the metallic debris and other contaminants from the air gap. Use a strip of
masking tape to remove the metal debris. Apply a strip of tape on the magnet
track and then remove it. Keeping the magnet track clean will prevent witness
marks. Witness marks are caused by metal debris being dragged across the surface
of the stainless steel by the magnet field of the moving coil. Witness marks have
no effect on the performance of the motor.
Motor Storage The motor storage area should be clean, dry, vibration free, and have a relatively
constant temperature. If a motor is stored on equipment, it should be protected
from the weather. All motor surfaces subject to corrosion should be protected by
applying a corrosion resistant coating.
