摘要： A motor control device for controlling a three-phase brushless motor that has a rotor and field coils includes: a load range determining unit that determines a rotor rotation angle range, in which the three-phase brushless motor becomes a load, as a load range when a short-circuit fault occurs in one of a plurality of switching elements. The load range determining unit determines a rotor rotation angle range, in which load current is presumed to flow through a closed circuit formed of the short-circuit switching element and any one of regenerative diodes connected in parallel with the respective normal switching elements when the rotor is rotated in a state where all the switching elements other than the short-circuit switching element are turned off, as the load range.

摘要： A sensorless controlling apparatus for controlling a brushless motor includes a speed calculator for calculating speed of a rotor ω, an angle calculator for calculating rotor angle θ at a predetermined time interval, and an angle controller for calculating correction angle Δθ based on the current value of a d-axis current (d-axis current value id), thereby controlling the rotor angle θ. The angle calculator uses the correction angle Δθ calculated by the angle controller, the speed ω calculated by the speed calculator, a predetermined time, and the rotor angle θ calculated by the angle calculator at a predetermined time to calculate the rotor angle at the predetermined time interval. Thus, the rotor angle θ calculated by the angle calculator is converged on the true angle of the rotor.

摘要： When one of six FETs has short-circuit faulted, a controllable region identification unit stops driving of an electric motor, and then performs processes for determining whether a short-circuit fault has occurred, and when a short-circuit fault has occurred, for identifying the position of the FET that has short-circuit faulted based on phase voltages (induced voltages) VU, VV, and VW of phases. When the position of the FET that has short-circuit faulted is identified, the controllable region identification unit performs a controllable region identification process. In detail, the controllable region identification unit identifies a “possible region,” an “indeterminate region,” and a “impossible region” based on phase voltages VU, VV, and VW of the phases.

摘要： When a short-circuited FET is identified as one of low-side FETs, maximum phase voltages of three phases are detected when a steering operation is performed by a driver, and the detected maximum phase voltages of the three phases are compared with one another to identify a short-circuit phase. On the other hand, when a short-circuited FET is identified as one of high-side FETs, minimum phase voltages of the three phases are detected when a steering operation is performed by the driver, and the detected minimum phase voltages of the three phases are compared with one another to identify a short-circuit phase.
