摘要： A yokeless stator for an axial flux machine, comprising a housing, the housing comprising a circumferential portion and a plurality of elongated portions extending radially inwards therefrom, and a plurality of discrete stator teeth arranged within the circumferential portion, each discrete stator tooth comprising a ferromagnetic material and an electrical winding; the housing further comprising an electrically isolating filling material filling empty space inside the housing. The circumferential portion of the housing is made of a first non-ferromagnetic material and the elongated portions are made of a second non-ferromagnetic material. The housing comprises a laminated structure, which comprises at least part of the plurality of inwardly directed elongated portions.
