Zusammenfassung:A motor assembly includes a stator having a stator core, stator windings, and a routing insulator configured to electrically insulate the stator core from the stator windings; a rotor rotatably received within the stator; and a bearing bridge received at least partially within the routing insulator and including a main body forming a center pocket arranged to support a bearing of the rotor shaft. A circuit board is provided including a circuit board, and an overmold structure forming an annular body on a surface of the circuit board arranged to mate with the main body of the bearing bridge to substantially seal the center pocket from ingress of debris particles.
