컴프레서용 극수변환 단상유도전동기의 권선배치 최적화에 관한 연구 = A Study on the Optimization of Winding Arrangement for the Pole Change Single-Phase Induction Motor for Compressor

다국어 초록 (Multilingual Abstract)

Methods of speed control of single-phase inuction motor include pole change and frequency control. Pole change method that is controlling the speed by converting the number of poles of the motor using only simple pole change device has lower capability of speed control than method of frequency control. However pole change method is more economical than method of frequency control because it has low manufacturing cost. In this paper we propose a method of improving the operating capability of 2-pole/4-pole using pole change method different from conventional method and the operating capability for each number of poles applied with the winding arrangement method is verified through finite element analysis.
