Calculation of Inductances in Permanent Magnet Type Transverse Flux Linear Motor

영구자석형 횡자속 선형전동기의 인덕턴스 산정에 관한 연구

The design and analysis of electrical machines often require analytical models for performance assessment and system simulation. Inductances are important parameters of these models. In this paper, the methods of calculating apparent and incremental inductances are introduced for a transverse flux linear motor, which has a peculiar coil shape. The computation is accomplished by nonlinear three dimensional finite element method(FEM) and equivalent magnetic circuit network(EMCN). The improved method has been verified by a test result.
