Abstract
A method of arranging windings in a parallel delta configuration in a stator assembly includes connecting a first lead of a first winding to a first terminal. The first terminal is electrically connected to a printed circuit board assembly (PCBA) located at a first axial end of the stator assembly. The method also includes wrapping the first winding about a first tooth of a lamination stack to form a first coil, extending the first winding about at least a portion of a circumference of the lamination stack at a second axial end of the stator assembly toward a second tooth located opposite the first tooth, connecting the first winding to a second terminal electrically connected to the PCBA, wrapping the first winding about the second tooth of the lamination stack to form a second coil, and connecting a second lead of the first winding to the first terminal.
