Abstract
Official abstract text for this publication.
The invention provides a stator for an electric motor comprising a plurality of radially inwardly extending teeth and comprising conductive material incorporated in one or more of the teeth.
First claim
Opening claim text (preview).
1 . A stator for an electric motor comprising a plurality of radially inwardly extending teeth and comprising conductive material incorporated in one or more of the teeth. 2 . The stator of claim 1 , wherein the conductive material is non-magnetic. 3 . The stator of claim 1 , wherein the conductive material is embedded in the teeth. 4 . The stator of preceding claim 1 , wherein the conductive material is in the form of rods embedded in the teeth. 5 . The stator of claim 4 , wherein the rods extend along the teeth from one axial end of the stator to the other axial end. 6 . The stator of claim 1 , further comprising means for shorting the conductive material. 7 . The stator of claim 6 , wherein the means for shorting comprises a shorting ring in contact with the conductive material. 8 . The stator of claim 7 , wherein the means for shorting comprises a shorting ring at each axial end of the stator. 9 . A motor comprising a rotor and a stator as claimed in claim 1 .
