Abstract
A monophase transverse circuit has two rows of cylindrical air gaps which are provided with conductors between terminal pairs, the terminal pairs are rotated at a quarter turn in order, a coil in the form of a flat double U-shaped arch remains global having consequent terminals by defining meanders between terminals which are laterally introducing opposite to a meander and whose sheets are now progressively attacked on one row of cylindrical or flat air gaps, thereby balancing axial forces, axial and opposite currents between adjacent slots convert a preceding ring-shaped flux into radial fluxes in the terminals by acting upon the rotor terminals with the same pitch and polarized by induction.

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 (24g).
