    摘要： A planetary gear assembly includes a gear housing, a carrier including a carrier flange positioned inside the gear housing, and a carrier shaft extending in an axial direction from the carrier flange toward a front side of the gear housing and coupled to a drum shaft, a sun gear including a front end that is coupled to the carrier while spaced apart from a back end of the drum shaft, and a back end that protrudes toward a back side of the gear housing and is coupled to a rotor frame of a motor, a key bolt including a bolt head coupled to the front end of the sun gear and a bolt shaft extending backward along the axial direction and penetrating the sun gear, pinion gears coupled to the carrier flange and tooth-coupled to the sun gear, and a ring gear tooth-coupled to the pinion gears.

    摘要： A washing machine comprises a rotatable drum for receiving laundry, a drive motor for the drum, a drive control for the drive motor and a washing machine control, the washing machine control being connected to the drive control. In a method of operating the washing machine for dry-spinning laundry at different and increasing speeds, wherein a certain speed is kept constant for a certain time in the manner of speed steps, the drum is at first rotated at a certain constant speed for spinning the laundry. The drive control monitors the motor current and records the variation over time of the motor current as well as an envelope curve of the motor current and an average of this envelope. The envelope of the motor current or its average is derived once after the time. As soon as the first derivative of the envelope or the average falls below a certain predetermined threshold value or becomes zero, the condition is defined that the spun laundry in the drum no longer loses any or sufficient water. Then the rotational speed of the drum is increased to a higher rotational speed, until the first derivative again falls below a certain predetermined threshold value or becomes zero.

    摘要： A circuit that increases input voltage to higher output voltage connected to a drive. The circuit can include a power input that receives the input voltage from a power source and at least one capacitor bank connected with the power input. A current-limiting surge suppressor is positioned between the power input and the at least one capacitor bank. The current-limiting surge suppressor includes a first current-limiting path and a second bypass path. A drain, when operable, dissipates the charge of the at least one capacitor bank. The drive is operable in response to the higher voltage output from the at least one capacitor bank.

    摘要： The present disclosure relates to a laundry treatment machine. A laundry treatment machine according to an embodiment of the present disclosure includes: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and outputting the converted AC voltage to a circulation pump motor; and a controller to control a speed of the circulation pump motor to be increased before a time point at which a speed of a washing tub motor increases. Accordingly, the washing tub motor and the circulation pump motor can be operated in synchronization with each other. As a result, it is possible to improve washing power based on circulation pumping during washing.
