Magnetic field analysis of claw-pole type generator using equivalent circuit is presented in this paper. On the basis of 3D geometry and flux paths, equivalent magnetic circuit is designed and field analysis is performed by solving the circuit. Non-linear characteristic of material is considered for precise analysis results. 3D FEA is performed to verify analysis results, and flux densities in rotor and stator regions are compared. Calculated no-load back emf for field input voltage and speed are verified by experiment. Comparing to 3D FEA, presented method provides precise results with instant calculation time.
