  • Circuit board assembly for compact brushless motor
    Patent number: 11955863
    Abstract: 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.

  • Method of generating hydrogen from the reaction of stabilized aluminum nanoparticles with water and method of forming stabilized aluminum nanoparticles
    Patent number: 10384937
    Abstract: A method of generating hydrogen gas from the reaction of stabilized aluminum nanoparticles with water is provided. The stabilized aluminum nanoparticles are synthesized from decomposition of an alane precursor in the presence of a catalyst and an organic passivation agent, and exhibit stability in air and solvents but are reactive with water. The reaction of the aluminum nanoparticles with water produces a hydrogen yield of at least 85%.
