초록

본 연구에서는 3상 유도전동기의 2단 제동기법올 제안하였다. 2단 제동기법이란 1단계로 제동용 커패시터에 의 한 자여자 제동법을 이용하며, 2단계로 3상 磁氣제동법을 이용하는 것으로 이는 장치의 구성이 비교적 간단하며, 저가의 비용을 필요로 하는 장점올 지니게 된다. 또한 제동특성올 시율레이션과 실험으로 확인한 결과 비교적 우수한 특성이 얻어짐올 알 수 있었다.

In this paper, two-stage braking method of 3-phase induction motrois proposed. This brake involves tow stages. The first stage is capacitor self-excitation braking, and the second stage is three-phase magnetic braking. In several applicatons, a low cost and effective brake is required for three-phase induction motor. A mechanical friction brake, typical braking method for induction motor requires external energy sources which is not safe, expensive and requires maintenance. Static and dynamic analyses of the proposed brake scheme are along with analytical result, simulated waveforms and experimental waveforms are compared. The experimental results shows good agreement with the simulated results.
