Abstract
이 발명은 스핀들 모터의 착자용 요크에 관한 것이다. 착자된 마그네트가 고정자를 이루고, 코일이 권선된 전기자에 전류를 흘려 회전력을 얻는 스핀들 모터에 있어서, 전기자를 이루는 요크에 다수의 홀을 수직방향으로 형성하고, 2개씩의 상기홀을 통하여 코일을 삽입 및 권선시키게 하는 요크의 구성을 이룬다. 이에 따라 권선되는 코일이 다른 주위의 홀에 권선되는 코일과 서로 일정한 갭을 이루게 되고, 홀벽에 완전히 밀착되어지며, 코일의 굵기에 상관없이 착자각 및 착자세기를 일정하게 유지시킬 수 있게 됨에 따라 모터의 회전불균일, 전기적 소음발생을 감소시키게 되며, 결과적으로 스핀들 모터의 전기적 성능향상 및 모터의 정밀하고 원활한 작동기능을 보장하게 되는 효과가 있다.This invention relates to a magnetizing yoke of a spindle motor. In a spindle motor in which magnetized magnets form a stator, and a current flows through a coiled armature to obtain rotational force, a plurality of holes are vertically formed in the yoke forming the armature, and the coils are inserted through the two holes. And a yoke for winding. As a result, the coils to be wound form a constant gap with the coils wound in other surrounding holes, are completely in close contact with the hole wall, and the magnetization angle and magnetization strength can be kept constant regardless of the thickness of the coil. It reduces the rotational unevenness of the electric noise and, as a result, improves the electrical performance of the spindle motor and ensures the precise and smooth operation of the motor.
