DC 편의된 다상 전원에 의한 횡자속 선형 유도 구동기 자기력의 왜곡 분석 = Analysis of Magnetic Force Distortion by DC-biased Multi Phase Input Applied in Transverse Flux Linear Induction Motor

다국어 초록 (Multilingual Abstract)

The magnetic force across the air-gap between primary and secondary part in linear induction motor is in most part constrained by bearing or linear guide. But, the existence of the normal force gives us a possibility to levitate and drive the secondary part of the linear motor stably without the bearing. Therefore, to control the normal force and the thrust force on the secondary part independently, the various methodologies have been presented. As one of the solutions, we suggest the decouple control by DC-biased multi phase input, in which the biased DC is modulated to control the normal force and the multi phase AC to control the thrust force. To guarantee the method, the distortion of the magnetic force is intensively analysed using the distributed parameter magnetic field theory for the transverse flux linear induction motor.
