Starting from the known rotating electromechanical converter comprising a stator with magnetic circuits and polyphase energizing windings, a first, inner, rotor with magnetic circuits and polyphase energizing windings, and a second (inter)rotor between this first rotor and the stator, provided with permanent magnetic members for co-operation with the magnetic circuit of at least the stator, the invention proposes to provide means for modifying the state of magnetization of at least a part of the respective areas of the second rotor which each lie between two successive permanent magnetic members. |
