ABSTRACT:
A system useful for controlling multiple secondaries of a linear disposed motor along an elongated path, with the system having a linear synchronous motor with its elongated primary disposed along the elongated path and at least one secondary responsive to the primary with means disposed thereon for attachment to a body to be propelled along the path, a plurality of linear synchronous motor drivers for providing inputs to designated coil windings of the primary for developing a traveling electromagnetic wave along the primary, a driver controller means connected to each motor driver which has plurality of memory sections for storing therein characteristics of waveforms for use in the system of the invention, a central controller for controlling the output of the plurality of driver controller means and a system computer for down loading instructions for the various waveform patterns to the memories of the driver controller means and for overall supervisory control of the system of the invention.
