Patent ID: 8395287

Claim:
An electric machine module comprising: a machine cavity; an electric machine including a stator assembly, the stator assembly including a first set of stator laminations and a second set of stator laminations, the first set of stator laminations including a portion having a first outer diameter, the second set of stator laminations including a portion having a second outer diameter larger than the first outer diameter, at least some of the second set of stator laminations each including first radial portions having a first radius and second radial portions having a second radius smaller than the first radius, the first radial portions and the second radial portions being staggered between one another; at least one circumferential coolant channel defined substantially around a circumference of the stator assembly by the first set of stator laminations and the second set of stator laminations; and at least one axial coolant channel defined substantially along an axial length of the stator assembly by the first set of stator laminations and the second set of stator laminations; a third set of stator laminations positioned at axial ends of the stator assembly, the third set of stator laminations including the first radial portions with the first radius along a lower portion of the stator assembly so that fluid communication between the plurality of axial coolant channels and the machine cavity is substantially prevented along the lower portion.
