Construction of motorized wheel for vehicle motorization

A motorization apparatus for a motorized wheel, comprising:

• an outer rotor including one of eighty, eighty-eight, or ninety-two poles constructed with segments of permanent magnet material sequentially magnetized north and south, the outer rotor adapted to be part of the motorized wheel and rotating with the motorized wheel about an axis;
• a stator core of ferromagnetic material spaced inwardly of the outer rotor and defining a clearance gap with the outer rotor such that the outer rotor is rotatable about the stator core, the stator core having an outer diameter ranging between 150 mm and 500 mm, the stator core having eighty-four slots and defining teeth between the slots;
• and
• a three-phase winding with coils of insulated wire being wound around the teeth of the stator core.

A motorization apparatus for a motorized wheel comprising:

• an axle adapted to be secured to a frame of a vehicle;
• a rotor unit including one of eighty, eighty-eight, or ninety-two poles constructed with segments of permanent magnet material sequentially magnetized north and south;
• a stator unit secured to the axle and made of ferromagnetic material spaced inwardly from the rotor unit such that the rotor unit is rotatable about the stator unit, the stator unit having an outer diameter ranging between 150 mm and 500 mm and having eighty-four slots with teeth defined between adjacent slots;
• a three-phase winding with coils of insulated wire being wound around the teeth of the stator unit, the arrangement of coils is adapted to be powered to induce a rotation of the rotor unit relative to the stator unit;
• a structure supporting the rotor unit relative to the stator unit such that the rotor unit and the structure rotate about the stator unit, the structure including hub portions rotatably mounted to the axle, lateral walls defining an inner volume for the rotor unit and the stator unit, and attachment members adapted to be connected to spokes of the motorized wheel, the attachment members being located radially inward of the clearance gap between the rotor unit and the stator unit;
• and
• a rim adapted to be connected to the spokes, the spokes extending from the rim to the attachment members and defining a wheel inner volume, wherein the rotor unit is located within the wheel inner volume.
