Abstract
An electromagnetic apparatus comprising two inductors generating a gliding magnetic field. Each inductor has a plane active face and the faces of the two inductors define a parallelepiped space therebetween to receive an armature. A plurality of pairs of rectilinear electrical conductors at each active face are associated to form two-phase imbricated windings connected in series within each inductor. The input conductor of each inductor is connected to the output conductor to form a single closed winding connected as a Wheatstone bridge. A two-phase generator feeds electric energy to the input conductors, one phase of the generator being connected between the points of junction of the two-phase windings of one inductor and the other generator phase is connected between the points of junction of the two inductors.
