The ring (1) has an integrated rotary electric motor (5) including a stator part (5a) fixed at a fixed collar (9), and a rotor part (5b) fixed at another rotary collar. The rotary collar includes a machined periphery zone (11b) receiving a support for a locating unit that locates an angular position of the rotary collar with respect to the fixed collar, and another periphery zone (11c) receiving a support for magnets (5b1) of the rotor part. The zones are arranged in a manner such that the zones define a support for an angular position locating band and the magnets, respectively. |
