Abstract

PURPOSE:To improve rhe performance of acceleration, by providing aspeed control with torque control elements by adding current limit functions correpsonding to a set point of the number of revolution to speed control. CONSTITUTION:When the number of revolution of a motor is lower than a set point and acceleration currents are required, deviation +DELTAn between the output of a revolution Setter 1 and the output of a revolution detector 2 is compared at a point 10 where the deviation is added to the output of a triangular wave generating circuit 9, and converted into pulse width corresponding to the value of +DELTAn. The output of the revolution Setter 1 and the output of the triangular wave generator 9 are added and compared at a point 11, and a set point of the number of revolution is changed into corresponding pulse width as acceleration current limit value. Each pulse wave a, b signals are added to an AND circuit 12, current command value Io'' obtained by smoothing the output and the output of an armature current detector 6 are added and subtracted at a point 7 and motor conductive currents are controlled. On the contrary when damping currents are demanded, the deviation -DELTAn of the number of revolution is smoothed by means of a smoothing circuit 13 according to a course of the broken line c, and the output is used as current command value.
