    摘要： The laundry treatment machine; absent a position sensor to sense a rotor position, includes a driving unit having a DC/AC inverter, an output voltage detection unit to detect output voltage applied to the motor, and an inverter controller to control the inverter to drive the motor based on the output voltage. The output voltage detection unit includes a plurality of resistors electrically connected between the inverter and the motor and a comparator to compare voltage detected by some of the resistors with reference voltage and to detect pulse width modulation (PWM)-based output voltage. Based on the PWM-based output voltage at least one switching device of the inverter is turned on. The output voltage detection unit outputs voltage detected by other some of the resistors to the inverter controller in a second mode in which all switching devices of the inverter are turned off.

    摘要： A washing machine includes a water tub, an electric motor, and a control device. The motor comprises a stator including a stator coil, a rotor magnet arranged circumferentially with respect to the rotor, and a control device. The rotor magnet includes a permanent magnet. When the control device applies a first voltage to the stator coil in a wash step of the washing operation, the rotor magnet is magnetized so that a magnetic flux of the rotor magnet acting on the stator is increased without reversal of a direction of magnetization. When the control device applies a second voltage to the stator soil in a dehydration step of the washing operation, the rotor magnet is magnetized so that a magnetic flux of the rotor magnet acting on the stator is reduced without reversal of a direction of magnetization as compared with the magnetic flux in the wash step.

    摘要： An appliance having a drain pump with a motor adapted to be supplied with an alternating supply voltage. A controller is adapted to monitor a current value supplied to the motor and to control the frequency of the supply voltage among a plurality of predetermined frequencies when the drain pump is operated in a full drainage mode. A storage medium associated with the controller stores for each predetermined frequency a maximum current value, a minimum current value and an optimal current value. The controller may stores computer implemented instructions for (a) determining if the monitored current value is between the maximum current value and the minimum current value, (b) comparing the monitored current value with the optimal current value, and (c) adjusting the frequency of the alternating supply voltage among the plurality of predetermined frequencies to cause the monitored current to more closely match the optimal current value.
