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.
