Abstarct: In this thesis, influence of structural factors and parameters (involved in) dominated in design process of a Claw Pole Transverse Flux Permanent Magnet (TFPM) machine on its performance are studied. These parameters include number of phases, number of poles, shape and length of air gap, ratio of magnet arc to flux concentrator arc in each pole of rotor, shape of pole shoe of stator, shape of flux concentrator of rotor, area of rotor pole covered by stator pole, the way that stators and/or rotors of different phases are put together, and skewing of rotor flux concentrators. The criteria used for evaluating the machine performance consist of an electromagnetic torque, cogging torque, iron losses and the dynamic transient performance characteristics. Due to their calculation, the internal voltage waveform and the armature winding inductance current are obtained by finite element analysis. In addition, the armature current waveform is calculated at different operating conditions through the simulation.
