Figure 6-8 - Parallel forcers
Parallel motors must not operate too close together to avoid curvature caused by magnetic fields. There must be
a minimum distance of 180mm between shafts. Due to the large attractive force between two shafts it is strongly
recommended that non-magnetic spacers or guides are used when installing parallel shafts.

Tandem Forcers 6.2.2.2
For tandem forcer installation there are several motor spacing and phase connections which will give the correct
phase sequence in the windings. The option that provides the smallest separation distance between the two
motors, and therefore the longest stroke, is with the motors mounted flange to flange with a 31.5mm separation
(Figure 6-11). The flange to flange orientation works for all motor model combinations. It requires a custom
armature cable which swaps the W and V connections on the second forcer to ensure the correct direction of
travel for both motors (see Figure 6-12 for connection diagram).
