Bumpers, Shock Absorbers, or End Stops
Include in your design a mechanical stop at each end of travel. Design the stops so
they can prevent the moving mass from leaving its travel limits. Take into
consideration the maximum speed and inertia of your moving mass when
designing your mechanical stops. The following diagram shows a minimal system
with mechanical stops.

Linear Encoder
Your linear motor components need 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 69 . It can also serve as
the carriage in a moving coil system or be designed into the base in a moving
magnet system.
