Abstract
In this paper, we investigate rotor design of claw pole alternators for automobile applications from the observations of detailed 3D flux paths in rotors. First, the electromagnetic field distribution is calculated by 3D nonlinear time-stepping finite element method that considers eddy currents generated at solid rotor core and laminated stator core. From the results, a novel rotor design is proposed to increase output of the alternator. Experimental verification is carried out to confirm the advantage of the proposed design. The mechanism of output increase by the proposed alternator is revealed by analyzing detailed 3D flux paths in the rotors.
