4. 발명의 중요한 용도4. Important Uses of the Invention

본 발명은 교류전원을 사용하는 기기에 직렬로 코일을 권선하지 않고, 병렬로 코일을 권선하기 때문에 코일의 저항값을 감소시켜 구동 전류값의 증가 및 구동 감도를 향상시킬 수 있는 효과가 있다.Since the coil is wound in parallel without winding the coil in series with an AC power source, the resistance value of the coil is reduced to improve the driving current value and the driving sensitivity.
