摘要： Triggered by a position detection sensor detecting that a rotor is positioned at any one of K predetermined electrical angles, for example, 60°, 180°, and 300°, a voltage vector to be given to a motor is updated. When, for example, the rotation frequency is equal to or higher than a specified value, the predetermined electrical angles is changed into M, for example, into one angle of 60°.

摘要： Two current threshold values are adopted, which are larger than the upper limit of current of an operating region. When a rotating speed is smaller than a speed threshold value, the current threshold value is adopted as a criterion to judge whether an input current to an inverter is abnormal, and when the rotating speed Rot is larger than that, the other current threshold value is adopted as the criterion.

摘要： The current-sensing circuit (1) includes a shunt resistor (R1) connected in series with a path of current from an inverter (106), an operational amplifier (12) amplifying voltage across both ends of this shunt resistor (R1) with a predetermined gain, a low-pass filter (18) averaging output voltage of this operational amplifier (12), and an arithmetic unit (50) calculating the current flowing through the path based on output voltage of the low-pass filter (18). The supply voltage of the operational amplifier (12) is set higher than the supply voltage of the arithmetic unit (50). The output voltage of the operational amplifier (12) is averaged at the low-pass filter (18) to a lower value than the supply voltage of the arithmetic unit (50).
