  • Motor controller having BEMF compensation for noise and/or vibration reduction
    Patent number: 12346093
    Abstract: Methods and apparatus for compensating for non-sinusoidal BEMF signals in an electrical motor using amplitudes, phases and orders of BEMF harmonic components and amplitude of 1st harmonic of BEMF of the electrical motor. First and second corrective components for vd and vq of the d-q coordinate system for the motor can be generated from amplitudes of the BEMF harmonic components and the angles of the BEMF harmonic components orders of the BEMF harmonic components and amplitude of 1st harmonic of BEMF.

  • THREE-PHASE MOTOR CURRENT MEASUREMENT
    Publication number: 20240291415
    Abstract: Methods and apparatus for controlling a three-phase electric motor by determining a duration of current measurement windows within a first pulse width modulation period for measuring motor current using a single shunt coupled to the motor. A duration of a first one of the current measurement windows can be adjusted by a time delta value to meet a minimum time to measure the motor current. A next PWM period can include compensation for the time delta value. In embodiments window adjustments are made by modifying the high state of a middle phase signal for phase signals to switches that energize the motor.
