Abstract

PURPOSE:To allow obtaining the speed controlling device of an electric car having constant torque control with week and stable torque pulse, by allowing torque control by slide frequency. CONSTITUTION:Instead of the limiter with slide frequency non ambiguously determined by a current limit value command 15, the current deviation of a constant current control system, i.e. the output of an amplification.compensation circuit 17 controls slide frequency. The constant current control at slide frequency in this manner minimizes high frequency current component to allow constant current and constant torque control for the current increase at voltage rise when change-over from three pulse modes to one pulse mode. Thus, the speed controlling device for an electric car having constant torque control with week and stable torque pulse can be obtained.
