Characteristic Analysis of Vector Controlled Linear Induction Motor Considering Static and Dynamic End Effect

정적 및 동적 단부효과를 고려한 선형 유도 전동기의 벡터제어 특성해석

Linear induction motor(LIM) have static and dynamic end effects due to its finite core length, so that per-phase impedances are asymmetric and the air gap flux distribution is distorted. So, this paper propose the d-q axis equivalent circuit and vector control method considering both static and dynamic end effects of the LIM. This vector control method consists of the slip frequency control, the time-invariant control and decoupling control. As a result, it is shown that the results of equivalent circuit method have a goof agreement with the results of finite element method.
