Tandem arrangement:
Master and stoker with the same cable outlet direction on the same
secondary section track
②
Janus arrangement:
Master and stoker with opposite cable outlet directions on the same sec-
ondary section track
③
Parallel arrangement:
Master and stoker with the same cable outlet direction on a separate
secondary section track
④
Anti-parallel arrangement:
Master and stoker with opposite cable outlet directions on a sepa-
rate secondary section track
Note
Requirements of coupled motors
•
Check the phase angles of the EMFs
•
Ensure that there is a sufficiently rigid mechanical coupling.
•
Position the motors as close together as possible.
•
The electrical parallel connection is not suitable for gantry applications.
If you connect linear motors in parallel on a shared secondary section track, the primary
sections must be positioned with a defined distance between them.
This produces matching phase angles of the EMFs. For separate secondary section tracks,
you must also consider the position of the tracks relative to each other.
Check whether the phase angles of the EMFs differ by no more than ±10° (see SINAMICS
S120 Commissioning Manual).
