Abstract

본 발명은 모터에 관한 것으로, 그 목적은 회전자의 요크구조를 개선하여 회전자의 요크 외주면에 부착되는 자석을 용이하고 견고하게 결합시켜 그 신뢰성을 향상시키는 것이다. 종래에는 회전자(30)의 자석(31)을 요크(32)와 결합시키기 위해 결속재(33) 또는 접착재등을 사용하여 고정시켰다. 그러나 본 발명에서는 회전자(30')의 요크(32')에 결합홈(50)을 형성하고 이결합홈(50)에 상응하는 크기의 자석(31')을 삽입 결합시킴으로써, 별도 결합 부재를 사용하지 않고도 자석(31')을 결합할 수 있고, 따라서 제조 공정이 단순화되는 이점이 있다.The present invention relates to a motor, the object of which is to improve the yoke structure of the rotor to easily and firmly coupled to the magnet attached to the outer peripheral surface of the yoke of the rotor to improve its reliability. In the related art, the magnet 31 of the rotor 30 is fixed by using a binding material 33 or an adhesive material in order to couple with the yoke 32. However, in the present invention, by forming a coupling groove 50 in the yoke 32 'of the rotor 30' and inserting a magnet 31 'of a size corresponding to the coupling groove 50, a separate coupling member is formed. The magnet 31 'can be combined without using, and therefore, there is an advantage that the manufacturing process is simplified.
