5.1 Function of components
Components in the multi-carrier system
Multi-carrier systems are modular transport systems with multiple workpiece holders based on
linear motors. A transport path consists of consecutively arranged motor plates with copper
windings.
The workpiece holders (carriers) move on the transport path. The carrier housings include a
secondary section that contains permanent magnets and a measuring magnet.
Each motor plate comprises one or more motor segments (primary sections). The copper
windings in the primary sections and the magnets of a secondary section together form
temporarily a linear motor.
The following overview illustrates the components in the multi-carrier system.

Component Function
1 Carrier Carrier for transporting workpieces
2 Secondary section with permanent
magnets
The counterpart to the motor segment in order to tra‐
verse a carrier
3 Measuring magnet Position detection of the carrier within the measuring
range of the motor encoder (for closed-loop-controlled
operation)
4 Motor encoder Determining the position of secondary sections within a
motor segment (for closed-loop-controlled operation)
5 Motor segment (primary section) Mating part to the secondary section.
The motor segment can be independently controlled.
6 SINAMICS S120 drive system Closed-loop control of one or more secondary sections
on a linear motor
