57AbstractABA direct -drive brushless DC motorization apparatus comprises an outer rotor with poles constructed with segments of permanent magnet material alternatively magnetized north and south. The outer rotor is adapted to be part of a wheel and rotating with the wheel about an axis thereof. A stator core of ferromagnetic material is spaced inwardly of said rotor to define a clearance gap with the rotor such that the rotor is rotatable about the stator core. The stator core has forty-two slots and defines teeth therebetween. 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.
