Title: Tension control including motor speed regulation system
IPC: B65H77/00
Filed: 1973-02-03
Abstract: This disclosure relates to a speed regulation system for a line speed pace motor for actuating strip material that is being wound or unwound in coil form by a reel motor. Diameter signals are generated which are a function of the instantaneous coil diameter D. Using field weakening for speed control of the reel motor, the coil has a defined diameter Do when the reel motor is at weakest field. Circuitry is arranged to receive the diameter signals and deliver control signals as a function of the instantaneous diameter for all diameters D</=Do. A speed regulation circuit for the line speed pace motor is connected to receive dual inputs, one being a speed command or reference signal, and the other being the control signals. The speed regulation circuit then delivers a constant speed signal to the line speed pace motor when D>Do, and a progressively decreasing speed signal to the line speed pace motor for all magnitude of D</=Do, so that at weakest field of the reel motor, the line speed is reduced progressively as a function of the instantaneous diameter.
