高調波를 利用한 三相籠型 誘導電動機의 低速制御에 관한 연구

Abstract

본 논문은 3상농형유?돛換엽綬? 고조파와 불평형회전자계를 이용하여, 100~400rpm의 저속범위에서 원활하게 속도를 제어할 수 있음을 보여주고 있다.

고조파의 발생은 변압기의 철손과 전동기의 공극으로, 불평형회전자계는 SCR의 한방향만의 위상제어와 오실레이터의 on-off 제어주파수로써 만들어지고 있다.

이 방법은 문부하와 정격부하에서 잘 적용됨을 알 수 있었다.

This paper presents the variable speed control of three phase inducation motor in the low region 100-400r.p.m. by using of the harmonics and unbalanced rotating magnetic field.

The generation of harmonics is made from the iron loss of transformer and air gap space of motor, and the unbalanced rotating magnetic field from uni-direction phase chopping of SCR and on-off control of oscillator.

The no load and full load condition is well satisfied by this techniques.
