This paper presents the influence of several structural factors and
parameters involved in the design of Claw Pole Transvers Flux Permanent
Magnet Machines (TFPMs) on their internal voltage. Knowing the influence of
each factor is very important for an effective process of design and
optimization for these machines. In this paper by using the complete design
algorithm of Claw Pole TFPM, only one parameter is changed at a time and its
influence on the internal voltage is analyzed. Output torque is also studied,
because the internal voltage has effect on both the average and the ripple of
output torque. The most important factors and parameters which are considered
are: 1) number of poles; 2) length of air gap; 3) ratio of magnet arc to flux
concentrator arc in each pole of rotor; 4) shape of pole shoe of stator and
5) area of rotor pole covered by stator pole. Due to geometrical complexities
of TFPMs, analytical methods fail to describe the behavior of these machines.
For this reason, in this paper finite element analysis is used both in the
design and analysis of TFPMs.
