Coupled motors
4.1 Parallel operation of several motors
CAUTION
If the angular position is set incorrectly, this can result in a thermal overload of one of the
two parallel motors during continuous operation at the rated load.
For this reason, it may be necessary to reduce the torque depending on the load to prevent
For this reason, it may be necessary to reduce the torque depending on the load to prevent
shutdown triggered by the PTCs.
Mechanical fine-tuning should always be carried out.

Motor arrangements
When two motors are operated in parallel, they can be arranged as follows:
Tandem arrangement
or
The cable outlets of the motors are located on the same side. When standard motors are
used, they both rotate in the same direction.
Janus arrangement
The cable outlets of the motors are located on opposite sides. When standard motors are
used, the stoker must be connected (as described below) in such a way that both motors
rotate in the same direction.
Master and stoker
The "stoker" refers to the second motor on an axes, which does not rotate in the same
Master and stoker
The "stoker" refers to the second motor on an axes, which does not rotate in the same
direction as the first motor ("master") with respect to the U V W phases. To ensure that the
stoker rotates in the same direction, the V and W phases must be swapped when the stoker
is connected.
