Abstract:
1. Variable reluctance polyphase dynamo-electric rotary machine ( 1 ), comprising a rotor ( 3 ) facing at least one stator ( 2 ), the rotor moving with respect to the stator ( 2 ) by rotation of the direction Z axis ( 9 ), with a local direction of movement X, the stator ( 2 ) comprising protruding stator poles ( 5 ), the rotor ( 3 ) comprising protruding rotor poles at constant pitch ( 7 ), and this rotor ( 3 ) comprising means of magnetic polarisation creating conditions of polarisation of the rotor poles in such a way as to have an alternating circulation of flux between stator poles ( 5 ) facing rotor poles ( 7 ), through at least one row ( 8 ) of air-gaps, the phases q of the machine being distributed forming elementary electric stator circuits ( 24 ) housed in elementary magnetic stator circuits ( 20 ) in order to constitute elementary stators ( 26 ), characterized in that an elementary stator ( 26 ) is single phase and comprises, on a single row ( 8 ) of air-gaps per elementary circuit, pairs of stator poles ( 5 ), facing a same number of rotor poles ( 7 ) of an elementary rotor circuit ( 21 ), in that the electric circuit ( 24 ) produces a reversal of polarity between angularly adjacent stator poles ( 5 ) belonging to a same phase q, in that the stator poles ( 5 ) are laminated by sheets in which the plane of one of the cross-sections is perpendicular to the local direction of movement X and in that the conductors of an elementary electric stator circuit ( 24 ) of a phase q comprise meanders ( 23 ) which alternately go around a stator pole ( 5 ) on the one hand and then the adjacent pole on the other hand in order to form a global elementary electric stator circuit with consequent poles ( 24 g ).
