Verfahren und Vorrichtung zur Steuerung von Asynchronmotoren in Parallele

摘要

This method for controlling asynchronous motors in parallel with a view to making, with all these motors, a set-point torque called the overall set-point torque, comprises a control for the one of these motors which is most loaded (m+), by automatic control of the torque provided by this motor (c+mes) to a set-point value (c+cons) defined by the addition to the mean set-point torque (cm,ccons), obtained by dividing the said total set-point torque by the number (n) of motors, of a corrective term corresponding to the algebraic sum of the torque deviations (Wc;+) of each of these motor (m1 ... mn), with respect to the most loaded motor (mr), divided by the number of motors (n).
