Impact of Claw-Pole Geometry Variations on the Performance of Machine used in Automotive Application
Résumé
This paper presents the influence of variation in
various geometric parameters of claw-pole topology on the
performance of machine used in automotive application. Due to
three-dimensional flux distribution in the claw-pole topology,
variation in geometric parameters of the claw-poles results into
change in performance of the machine. The geometric
parameters which have been varied are claw core outer diameter,
claw inside radius, claw side plate thickness and claw undercut
angle, and the performance of the machine has been evaluated
for the complete operational speed range from low speed of 600
rpm to high speed of 18,000 rpm. By carrying out the aforesaid
variations, it has been observed that there is a significant change
in torque during low speed operation.
