A direct-drive brushless DC motorization apparatus is provided. The apparatus includes an outer rotor having poles constructed with segments of forty or forty-four permanent magnets alternatively magnetized north and south. The outer rotor is adapted to be part of a wheel and is rotatable with respect to an axis of the wheel. The outer rotor is mounted about a stator core of ferromagnetic material and is separated from the stator core by a clearance gap. The stator core has forty-two slots, and adjacent slots are separated by teeth. A three-phase winding with coils of insulated wire is wound around the teeth of the stator core. The three-phase winding is divided in two sets of consecutive teeth for each of the three phases, with each of the two sets of a same phase being diametrically opposed in the stator core.

CONSTRUCTION OF MOTORIZED WHEEL FOR VEHICLE MOTORIZATION
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.
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.

In one aspect, the invention is directed to a watercraft that is drivable by a manual force input member and by a motor. The watercraft is configured to prevent the motor from back-driving the manual force input member. In a particular embodiment, the watercraft includes a hull, a propelling member configured to propel the hull through water, a manual force input member that is movable manually, an output shaft that is operatively connected to the propelling member and that is drivable by the manual force input member, a motor that is operatively connectable to the output shaft, and a one-way clutch connected between the manual force input member and the output shaft. The one-way clutch is configured to permit the manual force input member to drive the output shaft in a first rotational direction, and to prevent the output shaft from driving the manual force input member in the first rotational direction.
