FAST 3-D MAGNETIC-FIELD ANALYSIS OF TRANSVERSE FLUX LINEAR RELUCTANCE PROPULSION MACHINE BY FOURIER PROJECTION METHOD

This paper will propose a finite-element based Fourier projection method to analyze the magnetic field distribution for the transverse flux linear reluctance propulsion machine (TFLRPM). Since the machine moving direction is perpendicular to its magnetic flux plane, it is unavoidable to solve the finite element problem with 3-D form. The proposed method can project the 3-D magnetostatic Poisson's equation into three simplified Helmholtz's equations to solve the system magnetic field distribution in an efficient way. Through this modeling, the force pulsation phenomena and the flip-flop effect revealed in the machine system can be investigated.
