Coupling of Coil Units
A magnettrack can be shared by more than one slide. A servocontroller can be shared as well. The following
combinations can be distinguished (see figure).
1. Two (or more) coil units share a magnettrack, each of them directed by it’s own amplifier.
2. Two coil units are coupled (rigidly connected), sharing one amplifier and one magnettrack.
3. Two coil units are coupled, sharing one amplifier. They are running on different parallel tracks.
When two linear motors share one amplifier, they are connected in parallel. For motor sizing objectives the
currents of both motors should be added up. It is not possible to mount motors in series. Use one of the tem-
perature sensors. Use the sensor of the coil unit which is expected to have the worst cooling and also to reach
the highest temperature.
