The motor includes a stator (10) and two rotors (20) arranged on either side of the stator. The rotors include pole pieces (22) with permanent magnets (21) situated between the pole pieces. The stator comprises a magnetic circuit with teeth each serving as the core of a winding. The discoid electric machine includes a stator (10) and at least two rotors (20) arranged on either side of the stator in the direction of the rotors' axis. The rotors comprise pole pieces (22) with permanent magnets (21) situated between the pole pieces, the pole pieces concentrating the flux of the permanent magnets. The stator comprises a magnetic circuit with teeth each serving as the core of a winding. The teeth have plane parallel surfaces facing the rotors. The two rotors may be angularly shifted w.r.t. each other on their common axis. When the number of phases of supply (m) is even, the shift between the rotors ( alpha ), is defined by alpha = pi/S, where S=m.p, the number of teeth of the stator, and p is the number of pair of poles. When the number of supply phases is odd, the rotors are shifted by an angle defined by alpha = pi / 2S. |
