Development of a PM transverse flux motor with soft magnetic composite core

This paper reports the design, performance analysis, fabrication, and experimental results of a three-phase, three-stack permanent magnet transverse flux motor with a soft magnetic composite stator core, which was designed to take advantage of the unique properties of the new material. Parameter computations by finite element analysis of the magnetic field and performance prediction by the equivalent electric circuit are discussed. To validate the simulation, a prototype motor has been fabricated and operated with a sensorless, brushless direct coupler drive scheme. The experimental results are thoroughly presented and agree with the theoretical calculations very well.
