Abstract:
An electric motor includes a stator assembly including a lamination stack and a printed circuit board assembly (PCBA) coupled to the lamination stack at an axial end of the stator assembly. The stator assembly also includes a plurality of windings wrapped about the lamination stack to form a plurality of coils. The plurality of windings includes a first winding defining a first coil of the plurality of coils and a second coil of the plurality of coils located opposite from the first coil. The stator assembly further includes a plurality of terminals configured to electrically connect the plurality of windings to the PCBA. The plurality of terminals include a first terminal and a second terminal. The first coil and the second coil are connected in parallel between the first terminal the second terminal.
