Abstract
Official abstract text for this publication.
A stator ( 100 ) of an electric motor includes a coil ( 12 ), a stator core ( 10 ) which supports the coil, and covers ( 22 a, 22 b ) which are attached to the stator core so as to surround coil ends ( 13 a, 13 b ) of the coil, wherein the covers have outside diameters which are at least partially smaller than the outside diameters of the stator cores, the covers have coefficients of linear expansion which are larger than the coefficient of linear expansion of the stator core, and the covers expand due to heat whereby the covers closely contact the housing which is arranged around the stator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A stator of an electric motor comprising: a coil, a stator core which supports said coil, and covers which are attached to said stator core so as to surround coil ends of said coil which stick out from end faces of the stator core in the axial direction, wherein said covers have outside diameters which are at least partially smaller than an outside diameter of said stator core, said covers have coefficients of linear expansion which are larger…
