Cooling 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 air.
•
To provide good heat dissipation, reduce the thermal resistance by applying thermal conductive
silicon between the Motor Coil Unit and the moving table.
•
Provide adequate ventilation as required to prevent an excessive rise of the ambient temperature
because heat is dissipated in the air.
•
If the rise of the ambient temperature must be suppressed for a certain application, or if the size of
the moving table is smaller, configure a separate cooling system to cool the Motor Coil Unit.

Rigidity of Linear System
The response performance of a linear system is affected by the rigidity of the Linear Slider. Ensure
that the rigidity is appropriate for the required performance. If a gain is set to higher than the
machine rigidity, the vibration occurs.
Take the following measures to improve rigidity.
•
Use preloaded linear guides. This makes the Linear Slider highly rigid with less play in the
mechanical system.
•
Ensure the rigidity of the base material to which the Linear Slider is secured.
The materials in descending order of rigidity: granite, steel, and aluminum.
•
The moving table must have a sufficient thickness to prevent deformation and vibration.
•
Install the Magnet Track and external encoder in a straight and parallel line.
•
Install the external encoder as close to the Motor Coil Unit as possible.
