A Synchronous Wound Excitation Transverse Flux Machine with Solid Rotor

Abstract

This research study introduces a new synchronous transverse flux electrical machine, with iron solid rotor, stator in SMC iron powder, and wound excitation attached to the stator. The three-dimensional magnetic flux circulation fully exploits the soft magnetic composites isotropic properties. The steel rotor allows functioning at high speeds and in high ambient temperatures. Following the presentation of the machine, a simple analytical model confirms the concept. A finite element analysis allows a refined model and tests on a prototype motor validate the concept in the end.
