stops. The following diagram shows a minimal system with
mechanical stops.
Linear Encoder
Your linear motor components needs to be integrated with a linear
encoder purchased from a third party.
Carriage/Heat Sink
The linear motor coil requires a heat sink to maintain performance.
The heat sink requires a minimal mass and surface area as shown on
page 62 . It can as so serve as the carriage in moving coil system or be
designed into the base in moving magnet system.
Maintenance Linear motors require no maintenance when operated in a relatively
clean environments. 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. Use
a strip of masking tape to effectively remove the metal debris. Apply a
strip of tape in the magnet channel and then remove it.
Motor Storage 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.
