3.1.2 Coupling of motors
Individual ironless coil units can be coupled. This can be done using
two separate magnet tracks for gantry type applications or on a single
track to yield more force. This last option is especially interesting for
cost reduction in long stroke applications. By coupling two coil units
a smaller series coil and magnet yoke can be used. This will reduce the
magnet yoke cost. Different type of coil units within one series can be
coupled as long as they have the same motor force constant. The
forces of both coil units can be added up. Coil units must always be
connected to the drive in parallel, connection in series is not possible
because of voltage limitations of the cables. Refer to Appendix B. for
details about phase connections.

Mechanically the coupling can be performed in two different ways.
The first method is parallel coupling, in which there are two (or more)
rows of magnets with coil units. If the coil units face the same direc-
tion then they can simply be placed at the same position on each indi-
vidual magnet track parallel to each other. The second method is
in-line coupling, where several coil units are placed in the same row of
magnet yokes, see figure 3.2. In this case there are three possible ori-
entations: with the cable sides pointing to each other, away from each
other, or in the same direction, see figure 3.3. Details about minimum
mounting distances between both coil units can be found in Appen-
dix B. When coupling coil units, it is sufficient to use the temperature
sensors of only one of the coil units. Make sure that the cables of the
coil unit have approximately the same length so that the resistances
of the coil units will not differ too much.
Some coil units in the UC and UF series do have lateral cable exits.
There are still three possible configurations, although the cable orien-
tations are different then mentioned above.
The UC series coil units have no temperature sensors.
