Positioned on the teeth of rectangular cross section are tooth coils.
Claims12
An electric machine, comprising:
- a stator having slots of substantially rectangular cross section, wherein the slots are subdivided into pairs of slots, with each slot of each pair of slots configured with parallel flanks, wherein teeth are formed between the slots and have alternating rectangular and triangular cross sections;
- and
- tooth coils placed about the teeth of rectangular cross section.
An electric machine, comprising a lamination stack comprised of a plurality of lamination pieces, each lamination piece having circumferential slots in spaced-apart relationship of generally tetragonal cross section, wherein the slots are subdivided into sections of slots, with each section of slots defining at least one tooth therebetween and being separated from an adjacent section of slots by a tooth of generally triangular cross section, wherein the at least one tooth of each section of slots has attached thereto a tooth coil, wherein each of the slots of each section has parallel flanks.
An electric machine, comprising:
- a stator having a plurality of slots, wherein the slots are subdivided into pairs of slots, with teeth being formed between the slots and having alternating rectangular and triangular cross sections, wherein the teeth of rectangular and triangular cross sections have a radial dimension to define a circular boundary surface for an air gap;
- and
- tooth coils placed about the teeth of rectangular cross section.
