Abstract

An electric machine includes a stator having a stator core, rotor core and/or magnetic core comprising a plurality of slots. Each of the plurality of slots includes a spacer, a conductor, and encapsulated slot insulation. The spacer is configured to suspend the conductor away from the stator core by a dielectric distance without occupying all of the space between the conductor and the stator core. The encapsulated slot insulation includes an encapsulation material configured to flow in a liquid state around the perimeter of the conductor filling in the space between the conductor and the stator core. The encapsulation material cures to hold the spacer and the conductor in place. The encapsulated material typically has higher thermal conductivity properties than a conventional slot liner, increasing the performance of the motor.
