Claw pole motor

[sam55]

I need information about the Claw pole motors, their flux paths and flux density calculations in air gap. if anyone can help me I will be very happy. Thanks

if you have some schematics of magnetic core, then I can help you. gjovanoska@mt.net.mk

you mean claw pole motor or alternators.The most common formof rotor
in automotive alternator is claw pole.Anyway nowadays no body is doing any manual analysis of flux path etc.the best software is" infoltica".feed all information you will get it in seconds.

Abstract: A lumped-parameter coupled-circuit model of a claw-pole alternator is derived. To derive the model, analytical techniques are used to define a three-dimensional Fourier-series representation of the airgap flux density. Included in the series expansion are the harmonics introduced by rotor saliency, concentrated stator windings, and stator slots. From the alrgap flux density waveform, relatively simple closed-form expressions for the stator and rotor self- and mutual-inductances are obtained. The coupled-circuit model is implemented in the simulation of an alternator/rectifier system using a commercial state-model-based circuit analysis program. Comparisons with experimental results demonstrate the accuracy of the model in predicting both the steady-state and transient behavior of the machine.
