Abstract

Even when the V/F in a sensorless speed control method is constant, the control device of an electromotor can still increase the power-saving and the endurance of the electromotor. This invention discloses the control device of an electromotor comprising a voltage command regulating unit (15) having an input speed command (Ω ref) that can output a command voltage (V*) to an inverter circuit (2) and an integrator (4) using an integrating speed command to form a position command (θ ref). The control device of the electromotor has a current coordinate converter (5) that can convert the two-phase stator current coordinate formed by at least two of the phases of the stator current out of the three-phase current inputted from the inverter circuit (2) and outputted to the electromotor (3) and the position command (θ ref) into a γ -axis current (I γ) whose phase is the same as that of the position command and a δ -axis current (I δ) that is 90DEG higher than the position command. The control device of the electromotor has an inverter circuit (2) whose inputs are the command voltage (V*) and the position command (θ ref) and whose output voltage is applied to the electromotor (3). The inverter circuit (2) is composed of a γ -axis current commander (10) providing a current command whose position is the same as the position command (θ ref) on the <gamma> axis and a subtractor (14) that can output the aberration between a γ -axis current command (I γref) and the γ -axis current (I γ) to the voltage command regulating unit (15).
