    摘要： The laundry treatment machine, absent a position sensor to sense the rotor position of a motor, includes a driving unit having an DC/AC inverter, an voltage detection unit to detect output voltage, and an inverter controller to control the inverter. The output voltage detection unit includes a plurality of resistors 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. The voltage detection unit outputs the PWM-based output voltage output from the comparator to the inverter controller in a first mode in which at least one switching device of the inverter is turned on. The 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： Disclosed are a laundry treatment machine and a method of operating the same. The method of operating the laundry treatment machine that processes laundry via rotation of a wash tub includes accelerating a rotational velocity of the tub during an accelerated rotating section, rotating the tub at a constant velocity during a constant velocity rotating section, and determining an amount of laundry in the tub based on a first output current flowing through a motor that is used to rotate the tub during the accelerated rotating section and a second output current flowing through the motor during the constant velocity rotating section. This ensures efficient sensing of amount of laundry.

    摘要： Disclosed is a method for controlling a spin-drying cycle of a laundry treatment machine. The method includes performing a plurality of spin-drying operations by rotating a drum above an adjusted rotational speed range configured to adjust disposition of balls within a ball balancer so as to correspond to a changed amount of eccentricity, and adjusting the disposition of the balls within the ball balancer by rotating the drum within the adjusted rotational speed range, between the respective spin-drying operations.

    摘要： A washing machine includes a washing tub configured to accommodate laundry therein, a motor configured to rotate the washing tub, and a controller. The controller is configured to: determine a laundry amount and a laundry-tangled degree by using a plurality of types of data that are measured while rotating the washing tub at a specific rotational speed; set an allowable unbalance (UB) value corresponding to the laundry amount and the laundry-tangled degree; determine a UB value based on rotating the washing tub during a dewatering stroke; and control the motor to stop rotating the washing tub based on the UB value exceeding the allowable UB value.

    摘要： Washing machine technology, in which an initial speed in a drainage process is determined after a rinsing mode is finished, and a laundry distributing operation is performed in which a rotational speed of the motor is maintained at the determined initial speed. The washing machine determines whether a degree of laundry distribution satisfies an allowable range by comparing information detected by a vibration sensor with previously stored reference information. The initial speed is determined to be a rotational speed of the motor at an intersection time point at which vibration of a fundamental wave and vibration of higher harmonics detected by the vibration sensor intersect with each other.
