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.

Abstract: An electric motor control system, including an electric motor having a first winding set including first and second parallel windings, the first and second windings operable to each current based on the combined phase current, and a differential current sensor operably coupled to the first winding and the second winding. The differential current sensor measuring a differential current flowing through the first winding and the second winding and operable to transmit a signal indicative of the differential current based on the measuring. The system also includes a motor controller connected to the electric motor, the motor controller operable to direct the combined phase current through the phase lead, receive the differential current signal, determine if the differential current flowing through the winding set exceeds a selected threshold, and identify a health status of the motor winding set as degraded if the differential current exceeds the selected threshold.

Abstract: An insulating phase separator is used in an electric machine to separate phase windings in a stator assembly. The insulating phase separator includes first and second endturn portions and first and second leg portions. The first and second endturn portions each have a curved outer surface and a tabbed portion located opposite the curved outer surface. The first and second leg portions extend between the first and second endturn portions and are integral with the first and second endturn portions.

Abstract: A system comprises a stator core defining a plurality of winding slots between circumferentially spaced apart teeth. A respective cooling channel is defined within each of the circumferentially spaced apart teeth for circulation of coolant fluid through the stator core. The stator core is a laminated structure, where the teeth, winding slots, and cooling channels are part of a common laminated structure with the stator core.

Abstract: A stator core is provided and includes laminations disposed in a laminated arrangement to form a stator core body having an axial length extending in a lamination dimension. The stator core body includes an annular portion extending along the axial length and teeth extending radially from the annular portion and along the axial length. Each tooth has a trapezoidal shape and is formed to define one or more triangular holes running along the axial length.
