Abstract
A multipolar motor with two rotors includes two coaxial axially magnetised rotors (3, 5) arranged on either side of an intermediate stator part (17). First (13) and second (15) stator parts, each having a stator opening (19, 20), are respectively arranged on either side of the rotors. The first and second stator parts each have two polar expansions (13a, 13b, 15a, 15b) defining the stator opening. Each of these polar expansions is connected to the intermediate stator part (17) by a major electric circuit passing through the core (30) of a winding (33a, 33c).
