Abstract
A stator assembly is presented. The stator assembly includes a stator core defining slots and magnetic wires positioned within the slots. Each magnetic wire includes an electrically conductive core and an insulation layer surrounding the core. The insulation layer may have a varying thicknesses, with thinner portions spanning certain sides of the wires and thicker portions spanning other sides.
Claims20
A stator assembly comprising:
- a stator core defining a plurality of slots;
- and
- a plurality of magnetic wires in the slots, each of the magnetic wires having sides, an electrically conductive core, and an insulation layer surrounding the electrically conductive core, wherein portions of the insulation layer spanning some of the sides are thinner than portions of the insulation layer spanning other of the sides.
A traction motor comprising:
- a rotor;
- a stator core surrounding the rotor and defining a plurality of slots;
- and
- a plurality of wires arranged in the slots to form stator windings, each of the wires including an electrically conductive core and an insulation layer having a thickness that is asymmetrically distributed around the electrically conductive core.
1 more element
A method of manufacturing a stator assembly comprising:
- wrapping a plurality of wires within slots of a stator such that insulation covering sides of the wires facing a core of the stator is thinner than insulation covering sides of the wires facing adjacent wires within the slots of the stator.
