Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs
본 발명은 전압 구동 방식의 서보(servo)회로로 엑츄에이터를 구동시킬 때 구동 전류를 증가시킬 수 있는 코일 권선 방법에 관한 것이다.The present invention relates to a coil winding method capable of increasing a driving current when an actuator is driven by a voltage-driven servo circuit.
2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention
본 발명은 코일의 저항값을 감소시킬 수 있는 코일 권선 방법을 제공하는데 있다.The present invention is to provide a coil winding method capable of reducing the resistance value of a coil.
3. 발명의 해결방법의 요지3. The point of the solution of the invention
본 발명은 레이저의 광을 디스크에 정확하게 맺히게 하여 상기 디스크에 있는 정보를 읽어내는 대물렌즈와, 상기 대물렌즈를 지지하는 보빈과, 자기회로에 의해 상기 보빈을 포커스 방향 또는 트랙 방향으로 이동시키는 코일과, 상기 보빈을 지지하는 홀더를 구비하는 엑츄에이터 장치에서 상기 코일을 보빈에 권선 하는 방법에 있어서, 상기 코일의 저항을 감소시켜 상기 보빈에 인가되는 구동 전류를 증가시키도록 적어도 2개 이상의 코일을 권선하는 것이다.The present invention relates to an objective lens for accurately focusing a laser beam on a disk to read information on the disk, a bobbin for supporting the objective lens, a coil for moving the bobbin in a focus direction or a track direction by a magnetic circuit, And a holder for supporting the bobbin, the method comprising: winding at least two coils to increase a driving current applied to the bobbin by reducing a resistance of the coil; will be.
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.
