1.3.2 Parallel Arrangement, Serial Arrangement, and Symmetrical
Arrangement
One feature of linear motors is that multiple motors (coil sliders) can
be installed along one axis. For example, when the force obtained by
one motor is insufficient, two motors can be arranged along the same
axis to ensure the double force. This subsection introduces several
typical types of linear motor arrangements.
NOTE
Explanation in this subsection assumes that the coil
slider is used as the movable part. When the magnet
plate is used as the movable part, each arrangement
based on the same concept is available. There are
rules for the orientation and position of a motor,
however. For details of installation, see Part III,
"HANDLING, DESIGN, AND INSTALLATION."
Parallel arrangement
Two or more linear motors are arranged in parallel. As many magnet
plate tracks as the number of coil sliders are required. The length per
track is the same as that when one linear motor is used. The following
figure shows an example of arranging two motors in parallel:
Magnet plate track #1
Movable table
Coil slider #1
Coil slider #2
Magnet plate track #2
Serial arrangement
Two or more linear motors are arranged in serial. Only one magnet
plate track is required regardless of the number of coil sliders. It is
very difficult to arranger by using a ball screw and a rotation motor.
The length of the magnet plate track depends on the number of coil
sliders installed, however. The following figure shows an example of
arranging two linear motors in serial:
