Abstract
An apparatus and method for providing electrical insulation between adjacent end turns at different phases within a stator assembly. In one embodiment, the invention is directed to a stator assembly comprising: a stator core; at least two coils of different phases wound on the stator core through the slots and having an end turn that extends from the stator core; and one or more rigid separator members positioned between adjacent end turns of the coils.
Claims20
A stator assembly comprising:
- a stator core;
- at least two coils of different phases wound on the stator core and having an end turn that extends from the stator core;
- at least one elongated rigid separator member positioned between adjacent end turns of the coils and maintaining space between the adjacent end turns, the elongated rigid separator member constructed of a first dielectric material;
- and
- at least one flexible sheet constructed of a second dielectric material positioned between the adjacent end turns of the coils.
