Abstract — Magnetic field analysis of claw-pole type
generator using equivalent magnetic circuit is presented in
this paper. On the basis of 3D geometry, equivalent magnetic
circuit, which consists of permeance and magneto motiveforce
(MMF) source, is designed and field analysis is
performed by solving it. Non-linear characteristic of material
is considered for precise analysis results. 3D FEA is performed
to verify calculated results and flux densities in rotor and
stator regions are compared. Comparing to 3D FEA,
presented method gives precise results within instant
calculation time. Calculated no-load back-EMF for field input
voltage and speed of two models are verified by experiments.
