Abstract
An electrical machine stator can include a stator core having a stator core shape and made of a core material, a plurality of windings disposed in the stator core and made of a conductive material, and an insulative material surrounding the plurality of windings and configured to electrically insulate each winding from each other adjacent winding, and/or to insulate one or more of the windings from the stator core. The insulative material can be an amorphous metal.
Claims17
An electrical machine stator, comprising:
- a stator core having a stator core shape and made of a core material;
- a plurality of windings disposed in the stator core and made of a conductive material;
- and
- an insulative material surrounding the plurality of windings and configured to electrically insulate each winding from each other adjacent winding, and/or to insulate one or more of the windings from the stator core, wherein the insulative material is an amorphous metal.
A method, comprising:
- additively manufacturing at least one electrical machine stator layer including:
- a stator core portion having a stator core shape and made of a core material;
- a plurality of conductive material portions;
- and
- an electrically insulative material surrounding each conductive material portion to electrically isolate the plurality of conductive material portions from each adjacent conductive material portion and/or to isolate one or more of the conductive portions from the core material, wherein additively manufacturing includes using a directed energy deposition system comprising a plurality of nozzles connected to a plurality of build materials, further comprising controlling a proportion of the plurality of build materials output from each nozzle and/or an energy application setting during additive manufacturing to create the core material, the conductive material portions, and the insulative material, wherein the insulative material is an amorphous metal.
An electrical machine lamination, comprising:
- a stator core portion having a stator core shape and made of a core material;
- a plurality of conductive portions disposed in the stator core portion and made of a conductive material;
- and
- an insulative material surrounding the plurality of conductive portions and configured to electrically insulate each conductive portion from each adjacent conductive portion, and/or to insulate each conductive portion from the stator core portion, wherein the insulative material is amorphous metal.
