Abstract

PURPOSE:To make a drooping function work effectively only to the variation of load by removing adjustable speed currents from motor armature currents and detecting load currents corresponding to motor load currents. CONSTITUTION:A quasi-armature circuit 18a of a load current arithmetic circuit 23 inputs motor terminal voltage V and outputs adjustable speed currents Ia, and a subtracter 24 subtracts the motor armature currents I and the adjustable speed currents Ia and outputs the load currents IR corresponding to motor load torque. A motor generating power arithmetic device 25 computes motor generating power corresponding to load from the motor 9terminal voltage V and the load currents IR and outputs the power to a drooping quantity arithmetic circuit 22. Deviation between motor speed reference WR and the output DELTAWDR of the drooping quantity arithmetic circuit 22 is added to a motor armature circuit 18 through a speed control circuit 16 and a current control circuit 17.
