Abstract
An electric machine and stator assembly are provided that include a continuous stator portion having stator teeth, and a tooth tip portion including tooth tips corresponding to the stator teeth of the continuous stator portion, respectively. The tooth tip portion is mounted onto the continuous stator portion.
Claims17
A stator assembly, comprising:
- a continuous stator portion having a plurality of stator teeth;
- a tooth tip portion comprising a plurality of tooth tips radially opposed to corresponding stator teeth of the continuous stator portion, respectively, wherein the tooth tip portion is mounted onto the continuous stator portion to join the tooth tips to the radially opposed corresponding stator teeth;
- wherein the tooth tip portion comprises a continuous tooth tip structure formed from a single, continuous material;
- and
- wherein the continuous tooth tip structure is formed from a bi-state material, wherein bridge portions arranged between the tooth tips are non-magnetic following a heat treatment.
