Installation and Design Conditions
Mechanical Tolerance
Design and install a Linear Motor system that meets the following requirements.
Flatness of Motor Coil Unit mounting surface
Flatness of Magnet Track mounting surface
Accumulative pitch error of Magnet Track mounting screws
Parallelism between Motor Coil Unit and Magnet Track mounting surfaces
Center position of Motor Coil Unit and Magnet Track
Distance between Motor Coil Unit and Magnet Track
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.
