    • A washing machine and a method of controlling the washing machine are provided. According to the washing machine and method of controlling the washing machine, the drum is operated at a first speed so that part of laundry within the drum tumbles and another part of the laundry adheres to the drum. When an unbalance amount of the drum operating at the first speed is a first specific value or less, the speed of the drum is increased to a second speed so that all of the laundry adheres to the drum. When an unbalance amount of the drum detected during the increasing to the second speed is a second specific value or more, the rotation of the drum is decelerated. Accordingly, at a time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.
    • 提供洗衣机和洗衣机的控制方法。 根据洗衣机和洗衣机的控制方法,滚筒以第一速度进行操作,使得滚筒内部的衣物滚动,衣物的另一部分粘附在滚筒上。 当以第一速度操作的鼓的不平衡量是第一特定值或更小时,鼓的速度增加到第二速度,使得所有衣物都粘附到滚筒。 当在增加到第二速度期间检测到的滚筒的不平衡量是第二特定值或更大时,滚筒的旋转减速。 因此,在脱水循环时,可以确保洗衣机的稳定性和衣物平衡。

    • The present invention relates to a motor controller for an air conditioner and a motor control method. The motor controller including a converter converting AC utility power into DC power and an inverter having a plurality of switching elements, the inverter receiving the DC power, converting the received DC power into AC power by switching operations of the switching elements, and supplies the AC power to a motor, the motor controller further including: a current detector detecting a current flowing in the motor controller; a temperature detector detecting a temperature in the motor controller or a temperature ambient to the motor controller; and a controller calculating a loading based on at least one of room temperature, setup temperature, and inner unit capacity and setting up a final target frequency for driving the motor based on the calculated loading and at least one of the detected current and the detected temperature. The motor controller for the air conditioner and the motor control method determines a target frequency considering a current and a temperature, to reduce power consumption and protect circuit elements.
