7.1.2 SGLGW and SGLGM Linear Servomotors (Coreless Types)
3. When joining magnetic ways together, place the second magnetic way temporarily in line and at least 30
mm apart from the first magnetic way.
Next, after aligning the angles of the bolt sockets on the magnetic way's connecting surfaces, rotate the
second magnetic way to join the first magnetic way. Connect the second and first magnetic ways together.
And after confirming the mounting position, secure the second magnetic way using bolts. Make sure that
fingers do not get jammed due to the magnetic attraction between magnetic ways.
(2) Coil Assembly Installation
The coil assembly of SGLGW linear servomotor is constructed of an aluminum base and a resin-coated coil
winding section. Handle the coil assembly with care and do not subject the coil winding section to shock. Doing
so may cause injury or damage to the coil assembly.
Use the following procedure to install the coil assembly of SGLGW linear servomotor.
1. Insert the coil winding section of the coil assembly between the magnets of the magnetic way that has
already been installed. Next, install the movable table supported by the coil assembly's linear guide. Make
sure that the air gap between the coil assembly's coil winding section and magnetic way magnets is the
specified distance.
