Abstract

A stator assembly typically includes at least one stator core assembly that generates a magnetic field to rotate a rotor. The stator core assembly includes a core and a coil wrapped around the core to receive a current thus generating the magnetic field. To improve the performance and manufacturability of the stator assembly, a stator core assembly may include an insulator, disposed between the coil and the core, formed as a single flat sheet. A flat manufacturing process allows greater control of the insulator geometry, a broader range of materials to form the insulator, and patterning of structural features into the insulator to improve assembly and performance. The coil of the stator core assembly may also be electrically coupled to a bus bar using a fastener process and/or a crimping process that consumes less energy and occurs at lower temperatures than conventional soldering or welding processes.
