The electric rotary machine may be used as a speed variator and/or a torque converter. It comprises a stator (F) with s pairs of poles, a central rotor (RM) with p pairs of poles and an intermediate rotor (RT) comprising, at its inner face, at least one primary electric circuit subjected to the field of the central rotor (RM) and, at its outer face, at least one secondary electric circuit subjected to the field of the stator (F). A switching circuit controls the passage, in the secondary circuit, of the current produced in the primary circuit, in a direction such that the torque exerted by the stator (F) on the rotor (RT) is in the same direction. The invention applies particularly to motor vehicles. |
