Installation of coil <Mounting coil where magnet rail mounted. >
Step Description
1
After installing the entire magnet rail, place coil via nonmagnetic spacer whose thickness is more than
50mm to the magnet rail surface. Use the nonmagnetic spacer whose materials are not being
compressed by coil weight.
2
Place removal tap so that stage can be moved up and down in a horizontal direction with bolts. Stage
can be lifted up by contacting with the tip of removal bolt.
Use resin spacer so as not to scratch base even if removal bolt hits the base. Determine tap shape, the
number of tap, and spacer in consideration of magnetic attraction.
3
Place stage onto coil, fasten the coil and stage, lift the coil including stage by using removal bolts with
removal taps placed in the stage, separate coil from nonmagnetic spacer, and then remove the
nonmagnetic spacer.
4
Move the stage down to be locked with guide block in a parallel fashion by pushing removal screw down
in order. After that, remove the removal bolts. Stage positioning shall be performed where the space
between coil and magnet is wide and magnetic attraction is small.
Keep clearance 50mm or more between coil and magnet rail while installing, for the safety.
