Abstract: A three dimensional(3D) finite element model of a claw pole generator was presented using Rmxprt and Maxwell 3D of Ansoft. The distribution rules of leakage flux were analyzed by adding adjective faces in the 3D finite element model. The rules between the leakage flux and rotation speeds were analyzed on status with no-load and invariable excitation.
Key words: claw-pole generator; finite element method(FEM); leakage flux
