Abstract

본 발명은 스위칭소자를 이용하여 고정자권선의 접속배선을 절환시켜 주므로써 고정자의 극수를 변환시켜 사용할 수 있도록 한 극수변환형 유도전동기에 관한 것이다. 본 발명의 극수변환형 단상유도전동기는 2세트의 권선으로 이루어지며, 4극전환시에 4극의 회전자계를 발생시키는 제1주권선; 상기 제1주권선의 각 권선세트사이에 배치되는 1세트의 권선으로 이루어지며, 2극전환시에 상기 제1주권선의 각 권선세트와 협동하여 전체적으로 2극의 회전자계를 발생시키는 제2주권선; 상기 제1주권선의 각 권선세트와 어긋나도록 배치되는 1세트의 권선으로 이루어지는 2극보조권선 및 상기 제1주권선, 제2주권선 또는 2극보조권선의 해당 접점을 절환시켜서 극전환운전을 가능케 하는 스위치수단을 구비하여 이루어진다.The present invention relates to a pole number conversion type induction motor that can be used to convert the number of poles of the stator by switching the connection wiring of the stator winding using a switching element. The pole-number conversion type single-phase induction motor of the present invention is composed of two sets of windings, the first main winding for generating a four-pole rotating magnetic field when switching four poles; A second winding winding made up of one set of windings disposed between each winding set of the first winding windings and cooperating with each of the winding sets of the first winding windings to generate a two-pole rotating magnetic field when the two poles are switched; The pole switching operation is made possible by switching between the two pole auxiliary windings consisting of one set of windings arranged to be shifted from each of the winding sets of the first winding and the corresponding contact points of the first winding, the second winding or the two windings. It is provided with a switch means.
