Rockwell Automation LC-Series Linear Motor - Manual (Page 23)

Item Number 814036 - Rev C
Installation 2-17
4. Position the moving slide to the end of travel that you wish the cable to
exit. Making sure that the mounting face of the motor coil is clean and
free of burrs, install the motor under the slide. Select a M5 x 0.8 bolt
with a length that extends through the slide by 12 mm minimum, but
not more then 20 mm. Tighten snugly for now, bolts will be torqued
once installation is complete.
5. On the opposite end of the base, install the first magnet plate using M5
x 0.8 and 16 mm long SHCS. Non-magnetic tools and hardware
(beryllium copper, 300 series stainless steel, etc.) should be use. If not
available proceed with care since magnetic items will be attracted to the
magnet plates. Do not tighten bolts at this time. Install additional
magnet plates by placing them on the base and sliding towards the
previous install plate. Orient the plates such that the alignment holes are
toward the same side. This will ensure proper magnet polarity.
6. Move the slide, which you previously mounted motor coil to, over the
magnet plate. There may be some resistance while moving onto the
plate, this is normal. Measure the gap between the motor and magnet
using plastic shim stock. The gap should be 0.79 mm (0.031 in.) to
1.70 mm (0.067 in.). If gap is too large, add appropriate brass or stainless
steel shim between motor and slide. If gap is to small, machine the slide
or place shims under the bearing pucks.
7. Once the motor is gapped properly, install the remaining magnet plates.
8. The final alignment of the magnet plates are done with an aluminum
straight edge, and the alignment tool that was supplied with the magnet
plates. Slightly loosen the magnet plate mounting bolts, but not the ones
that are covered by the motor coil. Place the alignment tool in the holes
on each of the plates, this will properly position the pitch of the plates.
Align the edges of the plate with the aluminum straight edge and tighten
the bolts.
