Design & Comparison of a Conventional and Permanent Magnet based Claw-Pole Machine for Automotive Application
Résumé
This paper presents the design and performance
comparison of a conventional claw-pole machine with a
permanent magnet based claw-pole machine for automotive
application. The magnets are placed in the inter-claw region to
decrease the leakage flux and to supply increased magnetic flux
in the machine. It has been observed that with the addition of
permanent magnets weighing only a few grams, there is a
significant increment of more than 22% in output power of the
machine. The geometric dimensions of magnets were also varied
to verify their effects on performance and it has been observed
that with the increase in magnet weight there is a non-linear
increment in torque of the machine.
