The rotor shaft 16 is provided by the bearing 15 is pressed into the front and rear housing (10,11).
상기 로터샤프트(16)의 중도에는 로터코일(17)을 권취하여 후방의 슬립링(18)과 연결시킨 스풀보빈(19)이 압입되고 이의 외방에는 축방향으로 다수 개의 로터폴(20,21)을 가지는 로터코어(22,23)가 결합되어 스풀보빈(19)을 수용하는 구성으로 로터어셈블리(24)가 구비된다.In the middle of the rotor shaft 16, the spool bobbin 19, which is wound around the rotor coil 17 and connected to the rear slip ring 18, is press-fitted, and a plurality of rotor poles 20, 21 in the axial direction outside thereof. Rotor assembly 24 is provided in a configuration to accommodate the rotor core (22, 23) having a spool bobbin (19).
상기 로터어셈블리(24)의 슬립링(18)외방에는 로터 및 스테이터어셈블리(14)에서 발생하는 전압을 일정한 상태로 유지하는 전압조정기(25)와 교류를 직류로 전환하는 정류장치(26)가 고정된다.Outside the slip ring 18 of the rotor assembly 24, a voltage regulator 25 for maintaining the voltage generated by the rotor and the stator assembly 14 in a constant state and a stop value 26 for converting AC into direct current are fixed. do.
