1. A motor assembly comprising:
a stator including a stator core, a plurality of stator windings, and a routing insulator configured to electrically insulate the stator core from the plurality of stator windings;
a rotor rotatably received within the stator and including a rotor shaft extending along a longitudinal axis and a plurality of permanent magnets;
a bearing bridge including a main body forming a center pocket arranged to support a bearing of the rotor shaft, wherein the bearing bridge is received at least partially within the routing insulator; and
a circuit board assembly including: a circuit board, and an overmold structure forming an annular body on a surface of the circuit board, wherein the annular body projects from the surface of the circuit board and includes a smaller circumference than an outer circumference of the circuit board, the annular body being arranged to mate with the main body of the bearing bridge to substantially seal the center pocket from ingress of debris particles.
