Analysis of the Transient Phenomena of a Squirrel-Cage Induction Motor by means of the Spiral Vector method and the Phase Segregation method

감쇠회전 벡터법과 상 분리법에 의한 농형 유도 전동기의 과도현상해석

An induction motor can be controlled like a separately excited do motor by field oriented control(or vector control). In vector control, Because the transformation of the stator's 3-phase current into two orthogonal current is required. the control scheme is complicated. But, Yamamura proposed a field acceleration method(FAM) without the phase transformation. FAM simplify an implementation control scheme for induction motors. In this paper, the analysis of transient phenomena of a squirrel-cage induction motor was achieved by the spiral vector method and the phase segregation method. It simplified control schemes more than those of vector control.
