摘要： A washing machine motor drive device drives a motor using an inverter circuit, which implements a constant torque control through a change in the torque-revolution speed characteristic of the motor. This facilitates an easy control of braking torque (negative torque), thereby providing a maximized braking torque. An easy control of regenerative energy is also provided, and back electromotive force is consumed by the internal resistance of the motor. Practically described, DC power of a rectifier circuit connected to an alternating current source is converted by an inverter circuit into AC power for driving the motor for operating an agitator or a washing/spinning tub. Motor rotor position is detected by rotor position detector, motor current is detected by current detector, and a control device controls the inverter circuit for resolving the motor current into a current component corresponding to magnetic flux and a current component corresponding to torque. At a motor braking operation, the current component corresponding to magnetic flux and the current component corresponding to torque are controlled independently. As a result, the torque at high speed revolution can be increased, or the efficiency at low speed revolution can be improved. This leads to the use a downsized and energy-conscious motor, and contributes to the prevention of an abnormal rise of DC voltage in the inverter circuit.
摘要翻译：洗衣机电机驱动装置使用逆变器电路驱动电动机，其通过电动机的转矩转速特性的变化实现恒定的转矩控制。这容易控制制动转矩（负转矩），从而提供最大的制动转矩。还提供了对再生能量的容易控制，并且反电动势被电动机的内部电阻消耗。实际上，连接到交流电源的整流电路的直流电力由逆变器电路转换成用于驱动用于操作搅拌器或洗涤/旋转槽的电动机的交流电力。电机转子位置由转子位置检测器检测，电机电流由电流检测器检测，控制装置控制变频器电路，将电机电流分解成与磁通相对应的电流分量和与转矩对应的电流分量。在电动机制动操作中，独立地控制对应于磁通量的电流分量和对应于转矩的电流分量。结果，可以提高高速旋转时的转矩，或者可以提高低速旋转的效率。这导致使用小型化和节能型电动机，并且有助于防止逆变器电路中的直流电压的异常升高。

摘要： A washing machine apparatus includes an optical sensor which detects a light permeability of a liquid contained in a washer tank and a volume sensor which detects a volume of laundries contained in the washer tank. A minimum washing time and a maximum washing time of a washing cycle are set based on the detected volume of laundries. During the washing cycle, at a saturation time in which the detected light permeability becomes relatively constant, an overall light permeability change is detected. A remaining washing time is set based on the thus detected overall light permeability change, so long as the total washing time falls within the minimum and maximum set in accordance with the detected volume of laundries.
