Abstract

PURPOSE: To perform an operation control of little electrical power consumption by making speed controlling with change over to a low speed winding when a speed instruction signal not being at a vicinity of a maximum speed and moreover a speed detecting signal being higher than the speed instruction signal, and at other than this change over to a high speed winding.
CONSTITUTION: To a customary method which changes over a control mode according with a deviation of a speed instruction signal and a speed feed back signal, a signal to change over an amplitude of a speed instruction signal is added. By doing in this manner when a rated rotation instruction is issued, even if a chance to change a sign of a deviation of a speed instruction signal and a speed feed back signal should exist, a proper controlling is performed at both modes of powering and regenerating by a high speed winding all the times. Also at a time of deceleration even when a case of a speed feed back signal being above a speed instruction signal is happened, a proper controlling function is obtained by performing a control to change to a high speed winding powering mode from a low speed winding regenerating mode by an action of a contact B.
