Installing Linear Motor
Components Use one of the following procedures to install the magnet track or tracks and the
motor coil.
Required Tools
• Aluminum straight edge
• Non-magnetic M4 or M5 hex wrench
• Magnet channel alignment tool
Mount a Single Coil with Multiple Magnet Tracks
Follow these steps to install a single coil with multiple magnet tracks.
1. Clear the magnet track mounting surface of foreign material.
If necessary stone the mounting surface, acetone or methanol may be
applied as cleaning agent.
2. Verify the flatness of the surface to which the magnet track is to be
mounted.
Total Indicator Reading (TIR) is 0.127 mm (.005 in.) per
300 mm (12.0 in.). TIR or runout correlates to the overall flatness
requirement of the surface.
IMPORTANT The alignment tool is shipped attached to the cables next to the
Hall effect module. Remove before operating the linear motor.
TIP Use non-magnetic tools and hardware made of beryllium
copper, 300 series stainless steel. If these tools are not
available, proceed carefully as the magnet track attracts
magnetic and ferrous items.
ATTENTION: To avoid damage due to the magnetic attraction
between the magnet tracks, maintain a minimum distance of 1.5 m
(5 ft) between the magnet tracks that are being installed and the
magnet tracks awaiting installation. Keep the protective cardboard
and the metal plate in place until the installation is complete.
ATTENTION: Never attempt to place the coil assembly directly on
the magnet plates. Strong magnetic attraction will cause
uncontrolled movement causing a pinch hazard and possible
damage to the components.
IMPORTANT Do not use abrasives to clean the surface.
