摘要：Size and weight reduction of a motor-driven vehicle, robot or the like isachieved. A current command Iref from a speed feedback gain is supplied to each ofcircuits with coefficients of sin(θm), sin(θm+2π/3) and sin(θm−2π/3) to generate three-

phase signals. The three-phase signals are respectively supplied to current control gainsthrough adder-subtracters. Further, signals from motor constants are added together byan adder to produce motor torque. Furthermore, coil voltages output from adders passthrough diodes and are then added together by an adder, and the signal is supplied to aregenerative voltage determiner. When a regenerative voltage becomes excessive, in-phase current Idc is supplied through a regeneration control gain to adder-subtracters.
