Abstract: The paper is aimed at a 3D finite element analysis (FEA) based
investigation of the effects of the influent design parameters of a claw pole
transverse flux permanent magnet motor (TFPM) on its torque production
capability. As far as the three axially-arranged phases of the claw pole TFPM
are acting independently (there is no rotating field in a chaired air gap), the
present study is reduced to the case of a single phase concept. It has been
clearly shown that the claw pole TFPM could exhibit a high output torque if its
sizing is accurately achieved.
Keywords: transverse flux permanent magnet machine, claw pole concept, torque production capability, finite element analysis
