Design and Magnetic Circuit Analysis on Claw-Pole Permanent Magnet Generator for Vehicle Application
The rotor of claw-pole permanent magnet generator is constructed by two flangeHs with claw and a ringH of Nd-Fe-B permanent magnet magnetized axially,H axial fluxH is transformedH effectiveH radial fluxH, the polarityH of adjacent claw-poles is opposite, N poles and S poles array alternately. Based on design theory of permanent magnet generator, major parametersH of generator is determineHd. Using equivalent magnetic circuit method, the magnetic path of generator is analyzed, permeance and flux are calculated, thus the claw-pole permanent magnet generator is designed, it possesses high reliability, simple processH and effective voltage-stabilized characteristic.
