Abstract
A single stack transverse flux machine includes a rotor assembly having an internal rotor disc with a rotor shaft extending from and rotating with the internal rotor disc, and a rotor ring having a plurality of stator poles interleaved with a plurality of interpoles. The plurality of stator poles and the plurality of interpoles are radially disposed around the internal rotor disc. Each stator pole has a plurality of core components spaced apart from one another. Primary magnets are interposed between the plurality of core components. The machine also includes a stator assembly with a plurality of shaped cores, each shaped core having a base with a plurality of legs with a corresponding gap therebetween. Each leg has a winding, and the shaped cores are positioned so that each leg is juxtaposed with a corresponding one of the plurality of core components and has an air gap therebetween.
