Path module for a linear motor, modular linear motor system and method to control same

摘要

A path module for a linear motor system includes a controller coupled to one or more amplifiers that are operative to control associated windings in the module. The controller receives control information via a communications link. The controller controls the amplifier based on the received control information so as to selectively energize the associated windings in the module. In one aspect, a plurality of such modules may be connected together to form a path along which one or more stages are moveable according to energization of the windings in the path.
