Abstract (en)
[origin: WO9516300A1] An electric motor-wheel including a hollow shaft capable of receiving leads from outside the motor-wheel, a stator coaxial with and fastened to the shaft, and a rotor coaxial with and rotatable about the stator. The rotor includes a housing with a cylindrical wall having an inner surface provided with a magnetic assembly arranged around the stator and separated therefrom by an air gap, and the housing includes an inner wall on one side of the cylindrical wall, and an outer wall on the other side of the cylindrical wall. The shaft extends through a central portion of the inner wall, and the outer housing wall includes alternately convex and concave sections extending in the circumferential direction thereof so that during rotation of the rotor, air is circulated within said housing by the convex sections, and along outer portions of the concave sections to enable an efficient exchange of heat through the outer wall.
