Description
본 발명은 풍력발전기에 사용되는 발전기에 있어서 영구자석을 감싸는 하우징을 결합하여 조립할 수 있도록 하여 조립시 발생할 수 있는 불량률을 줄일 수 있도록 한 것이다.The present invention is to reduce the defect rate that can occur during assembly by assembling the housing surrounding the permanent magnet in the generator used in the wind turbine.

Commonly used generators include a housing consisting of a front, rear bracket and a hollow body, a rotating shaft installed through the housing, a rotor core press-fitted to the rotating shaft to rotate in conjunction with the rotating shaft, and the rotor core. A permanent magnet generator having a magnet attached to an outer circumferential surface to form a magnetic field and a binder wound on the outer circumferential surface of the magnet so as not to be separated from the rotor core and formed of a steel sheet is used. The magnets inserted into the openings formed in the rotor core were combined with a binder so that the magnet was firmly attached to the rotor core.
그러나 위와 같은 종래의 발전기는 마그네트를 회전자코아에 조립하는 과정을 바인더로 결합하므로 조립과정이 복잡하고 마그네트 상호간의 거리를 맞추기 어려운 문제점이 있었다.However, since the conventional generator as described above combines the process of assembling the magnet to the rotor core with a binder, the assembly process is complicated and it is difficult to match the distance between the magnets.
상기 문제점을 해소하기 위하여 회전자 코어에 홈을 형성하고 상기 홈에 마그네트를 조립하는 방법이 개발되었는데 이때 마그네트를 조립하기 위하여 홈에 마그네트의일측을 맞춘 후 타측에서 압력을 가하던가 충격을 주어 결합하게 되는데 이때 조립과정에서 마그네트에 충격이 주어지므로 마그네트가 파손될 위험이 있다.In order to solve the above problem, a method of forming a groove in the rotor core and assembling the magnet in the groove has been developed. At this time, there is a risk that the magnet is broken because the magnet is given an impact during the assembly process.
본 발명은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로 마그네트의 주면을 감싸는 하우징을 조립한 후 하우징에 압력을 가해 조립하므로써 조립불량을 미연에 해소할 수 있도록 함을 목적으로 한다.The present invention has been made in order to solve the above problems is to assemble the housing surrounding the main surface of the magnet and to assemble by applying pressure to the housing to solve the premature failure.
