    • A motor control system has a sensor for measuring an operational parameter of a motor and includes means for converting the measured operational parameter into an electrical resistance value. The operational parameter measured by the sensor is the rotational speed of the motor which is converted into a back electro-motive force value. The back electro-motive force value is then used, along with a measured input voltage value and measured motor current value to calculate the electrical resistance as value. The electrical resistance value is then compared to a threshold value and in the case that the threshold value is reached, the current flow in to the motor is adjusted.
    • 电动机控制系统具有用于测量电动机的操作参数的传感器,并且包括用于将所测量的操作参数转换为电阻值的装置。 由传感器测量的操作参数是电机的转速转换为反电动力值。 然后使用背电动力值,以及测量的输入电压值和测量的电动机电流值,以计算电阻值。 然后将电阻值与阈值进行比较,并且在达到阈值的情况下,调节到电动机的电流。
