Abstract
An electric machine within a hub housing rotatably disposed on an axle. A magnetic rotor is mounted on and can be rotated about the axle and is driven by the rotation of the hub housing by means of a transmission. The magnetic rotor comprises a central support carrying a plurality of axially aligned permanent-magnetic rods arranged in a star-shaped configuration. A coil assembly in the form of a cylindrical shell is arranged around the magnetic rotor. This design results in a compact and easy to assemble configuration with an overall efficiency higher than 0.5.
