Abstract (en)

[origin: WO2016092262A1] A method of operating a motor in an electric supercharger, the method comprising operating the motor in a first, low-Noise Vibration and Harshness (NVH), mode in which the timings of the current supply of each phase are obtained from a first source in which the timings are selected for low-NVH; monitoring a temperature of the motor; and in response to the monitored temperature exceeding a predetermined threshold, switching operation of the motor into a second, lower- temperature, mode in which the timings of the current supply of each phase are selected for generating lower temperatures in a controller of the switched-reluctance motor.
