(2) Moving Coil Installation
The SGLTW moving coil is constructed of an aluminum or steel base and iron core,
with a resin-coated coil winding section. Make sure that the coil winding section is
not subjected to shock during installation. Shock may damage the moving coil.
Use the following procedure to install the SGLTW moving coil.
1.
Install the moving coil on the movable table supported by the linear
guide in line with the already installed magnetic way.
Make sure that the air gaps between the moving coil and magnetic way’s
magnets is the specified distance.
Maintain the following air gaps when installing. Make sure that the
moving coil and magnetic way do not interfere with each other during the
stroke.
