Abstract
An electric motor is provided including: a stator assembly having a lamination stack defining poles and magnet wires wound on the poles, and a rotor rotatably arranged inside the stator assembly. A mount having a curved profile and made of non-conductive material is provided. Conductive terminals are mounted on and secured to a first surface of the mount, the conductive terminals being separated and insulated from each other via portions of the mount. A second surface of the mount opposite the first surface is mounted over to an outer surface of the lamination stack in contact therewith to align the plurality of conductive terminals longitudinally along the outer surface of the lamination stack.
