Abstract
본 발명의 세탁기 모터속도 제어방법은, 외부로부터 인터럽트 신호가 입력되면 내부타이머로 1주기 펄수를 카운팅하고 주파수를 판별하는 과정과, 상기 자파수가 50㎐이면 모터를 허용최대속도로 동작시키는 과정과, 상기 주파수가 50㎐가 아니면 인터럽트 타임을 결정하고 그에따라 세탁과 탈수운전속도 및 위상각을 제어하는 과정을 포함하여 구성되며, 상기와 같이 50㎐의 사용주파수를 기준으로 세탁기를 설계하고, 60㎐시에는 위상각을 제어하여 세탁, 탈수시 최대 회전속도를 일정하게 함으로써 세계 어느지역에서나 사용할 수 있는 효과가 있다.In the washing machine motor speed control method of the present invention, when the interrupt signal is input from the outside, counting the number of pulses per cycle with an internal timer and determining the frequency, and if the magnetic wave number is 50 Hz, operating the motor at the maximum allowable speed; If the frequency is not 50 kHz, including the process of determining the interrupt time and controlling the washing and dehydration operation speed and phase angle accordingly, and design the washing machine based on the operating frequency of 50 kHz as described above, 60 ㎐ The city has the effect that it can be used anywhere in the world by controlling the phase angle to make the maximum rotation speed constant during washing and dehydration.
