  • Patent number: 10625819
    Abstract: A motorization apparatus for a motorized wheel comprises an axle secured to a frame of a vehicle. A rotor unit has poles of magnet material. A stator unit having slots and teeth secured to the axle is inward of said rotor to define a clearance gap therewith such that the rotor unit is rotatable about the stator core. An arrangement of coils is wound around the teeth of the stator unit, the coils adapted to be powered to induce a rotation of the rotor unit relative to the stator unit. A structure comprises hub portions rotatably mounted to the axle, the structure having lateral walls defining an inner volume for the rotor unit and the stator unit, the structure supporting the rotor unit. The structure comprises attachment members connected to spokes of the motorized wheel, located radially inward of the clearance gap between the rotor unit and the stator unit.

  • Publication number: 20150298537
    Abstract: A wheel motor comprises a stator portion comprising a core secured to an axle and defining air-circulation openings extending through the core, a stator ring mounted about a periphery of the core. The stator ring has teeth separated by slots and windings on the teeth, the windings are connected to a wheel motor controller. A rotor portion comprises an annular case, and structural members rotatably connecting the annular case to the axle, the annular case enclosing permanent magnets opposite the teeth of the stator portion. The structural members define an air-circulation openings extending through the rotor portion. A shielding configuration is between the annular case and an annular surface of the stator portion radially spaced from the axle to define a shielded chamber enclosing the stator ring. The sealed chamber is radially outward of air channels concurrently defined by the air-circulation openings in the stator portion and the rotor portion.

  • Patent number: 6035976
    Abstract: A brake is constructed so that a brake pad contacts the road surface by moving down an inclined plane. The geometry of the design results in a braking force that is large in comparison to the force applied by the user of the brake, allowing for very quick stops. The brake has particular utility for streetluges and go-carts, but could also be used on roller skates, inline skates, and skateboards.
