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.
