Abstract
본 발명은 세탁기의 회전익 구동제어장치 및 방법에 관한다. 본 발명의 회전익 구동제어장치는 입력 교류전원을 정류하여 회로의 각부에 필요한 동작전원을 공급하는 직류전원 발생부와; 세탁기의 회전익을 좌우로 반전회전시키기 위한 무정류자모터와; 무정류자모터의 각각의 상권선을 교번적으로 통전시키기 위한 모터구동부와; 상기 모터의 회전수를 검출하기 위한 회전수검출부 및 상기 회전수검출부로부터의 신호에 의거하여 현재의 회전수를 판단하고 이를 미리 설정된 기준회전수와 비교한 후 필요한 제어를 수행하는 마이크로프로세서로 이루어진다. 상기한 구성에서, 무정류자모터는 3상모터로 양호하게 구현될 수 있으며, 상수의 증감도 가능하다. 모터구동부는 각 상권선에 쌍으로 연결되는 복수개의 전력 스위칭트랜지스터로 구현될 수 있는바, 마이크로프로세서의 제어신호에 따라 각 상권선의 통전시간을 제어하게 된다. 모터회전수검출부는 홀(Hall)센서로 양호하게 구현되는데, 모터의 회전자의 각극에서 발생되는 자계에 의하여 유기되는 펄스전압신호를 마이크로프로세서에 제공한다.The present invention relates to a rotorcraft drive control apparatus and method for a washing machine. The rotary blade drive control apparatus of the present invention includes a DC power generating unit for rectifying the input AC power to supply the operating power required for each part of the circuit; A non-commutator motor for reversely rotating the rotor blades of the washing machine from side to side; A motor driving unit for alternately energizing each of the winding wires of the non-commutator motor; A rotation speed detection unit for detecting the rotation speed of the motor and a microprocessor for determining a current rotation speed based on a signal from the rotation speed detection unit, comparing the current rotation speed with a preset reference rotation speed and performing necessary control. In the above configuration, the non-commutator motor can be implemented well as a three-phase motor, it is possible to increase or decrease the constant. The motor driver may be implemented as a plurality of power switching transistors connected to each of the phase winding lines. The motor driver controls the energization time of each phase winding line according to a control signal of the microprocessor. The motor speed detection unit is preferably implemented by a Hall sensor, and provides a microprocessor with a pulse voltage signal induced by a magnetic field generated at each pole of the rotor of the motor.
