INSTALLATION
CH 3
Placement of just one yoke on each side of the middle yoke can be done by
simply aligning the yokes with respect to each other.
There is no danger of mounting the magnet yokes with an incorrect orien-
tation, the standard yokes are “Murphy-safe”. A 180° rotated yoke does not
have any effect on the motor function.
3.6 Coil unit mounting instructions
Be sure that the mounting surfaces are free of contamination.
Particles > 0.1mm can cause inaccurate placement and
consequently damage to your Linear Motor.
The mounting of the coil unit on appropriate and clean mounting surfaces is
very straightforward because no attraction forces are present between coil
unit and magnet yokes. Please review chapter
The coil unit can be placed into the machine by hand carefully, pushed to
the axial reference and fixed with bolts. Tightening torque of the bolts as
prescribed in chapter
2.1 Basic components on page 7
For applications which are susceptible to vibrations, the bolts
have to be secured against loosening by means of rings or
(Loctite) thread lock.
In case of high continous forces, apply a heatsink compound to
obtain optimal thermal contact between the coil unit and the
mounting surface.
3.7 Electrical connections
Before starting any activity on the wiring, make sure that the
mains are disconnected. Work carefully according the instructions
belonging to the applied servo controller. Be sure your machine
as a whole meets the requirements of all applicable electrical
standards, such as the EN 60204 standard.
3.7.1 General remarks
The linear motor’s electrical wiring is externally configured with two 1.0
meter cables: a power cable and a temperature cable. If desired you can
shorten these cables and provide them with appropriate connectors.
The UXA/UXX3S is delivered with a FLEX cable of 3m. Suitable for cable chains.
Both power cable and temperature cable are shielded with a braided
metal cable shield for electromagnetic immunity. The shield is galvanically
connected inside the coil unit housing.
Besides this manual you should follow carefully the installation instructions
of your servo amplifier supplier. Make sure that the linear motor system as a
whole meets all the applicable electrical directives.
For wiring scheme of the UM, UL,UXA and UXX series see figure 3.8.
The wiring scheme of the UF type is shown in figure 3.9.
The wiring scheme of the UC type is shown in figure 3.10.
The UC coil is supplied with a five wire cable. The green and the yellow wire
do not have a function.
