Design and install a Linear Motor system that meets the following requirements.
z
Magnetic Attraction Force
In the Linear Motor, a magnetic attraction force is exerted between the Motor Coil Unit and the
Magnet Track, which (calculated value) is shown in the table below.
Design a system with consideration of the magnetic attraction force.

Thermal Conductivity of Motor Coil Unit
• The Motor Coil Unit becomes hot during operation. For the Motor Coil Unit, install a moving table
(radiator plate) of the recommended dimensions or larger to provide sufficient heat dissipation into
the moving table and air.
• Make sure that there is a thermal contact between the Motor Coil Unit and the moving table. To
provide good heat dissipation, apply thermal conductive silicon.
