Abstract
A permanent magnet machine includes a machine housing and a stator. The machine housing has an inner surface. The stator is disposed within the machine housing. The stator has a stator core having an exterior surface. At least one of the inner surface and the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface.
Claims4
A permanent magnet machine comprising:
- a machine housing having an inner surface that extends between a first housing end and a second housing end along a central longitudinal axis;
- and
- a stator disposed within the machine housing, the stator having a stator core having an exterior surface extending between a first face and a second face along the central longitudinal axis, at least one of the inner surface and the exterior surface defines a discontinuous region that is arranged to minimize points of contact between the inner surface and the exterior surface, wherein the discontinuous region is defined by a circumferential gap and an axial gap disposed between a first raised region and a second raised region, the first and second raised regions each extending radially outwardly from the exterior surface of the stator core, the first raised region comprising a pair of raised segments axially aligned and circumferentially offset from each other, the second raised region comprising a pair of raised segments axially aligned and circumferentially offset from each other, wherein the first raised region and the second region are axially offset from each other.
