  • Patent number: 10886868
    Abstract: A motor control apparatus includes an inverter comprising switching elements, current detection means for detecting a phase current value output from the inverter to each phase of a three-phase AC motor, conversion means for converting the phase current value into a digital AD conversion value, and modulation means for comparing a phase voltage command value based on the AD conversion value from the conversion means with a PWM counter value generated using a timer operating at predetermined cycles to generate a PWM signal and outputting the generated PWM signal to the inverter to thereby switch the switching elements of the inverter and control the three-phase AC motor. The conversion means outputs the AD conversion value acquired by converting the phase current value at a timing when a rectangular width of a rectangular wave of a phase voltage value corresponding to the PWM counter value is long.

  • Patent number: 10707797
    Abstract: A motor control apparatus includes a current estimation unit configured to output a detected current value corresponding to each of the three-phase AC currents based on the measured current value and rotor rotation angle information of the motor. The current estimation unit defines a phase whose duty ratio of a driving pulse supplied to an inverter circuit, which generates the three-phase AC currents, becomes more than or equal to an operation switching threshold as an estimation target phase, calculates, for the estimation target phase, an estimated current value based on a coefficient value, which is calculated from the measured current value by the current measurement unit in a period in which the duty ratio of the driving pulse is lower than the operation switching threshold, and the rotor rotation angle information, and outputs the calculated estimated current value as the detected current value of the estimation target phase.
