SYSTEM ZUR VERWENDUNG SYNCHRONER SEKUNDÄRKREISE EINES LINEARMOTORS ZUM BIAXIAL-ZIEHEN VON KUNSTSTOFF-FOLIEN.

摘要

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 (152) disposed along the elongated path and at least one secondary (160) responsive to the primary with clips disposed thereon for attachment to a body to be propelled along the path, a plurality of linear synchronous motor drivers (136, 140, 144, 148) for providing inputs to designated coil windings of the primary for developing a traveling electromagnetic wave along the primary, driver controllers means (128, 130, 132, 134) connected to each motor driver which has plurality of memory sections for storing characteristics of waveforms for use in the system of the invention, a central controller (108) for controlling the output of the plurality of the driver controllers and a system computer (100) for down loading instructions for the various waveform patterns to the memories of the driver controllers and for overall supervisory control of the system of the invention.
