Abstract: A magnetic core (3) surrounded by a coil (1, 2) bears a first pole shoe (4) forming a large-surface air-gap with two zones (5a, 6a) of two armatures (5, 6) fixed to one another and disposed magnetically in parallel.The core (3) is continued beyond the coil and at this end bears a second pole shoe (9) which together with two other zones (5c, 6c) of the armatures forms a second large-surface air-gap disposed magnetically in series with the first.

Abstract: The electromagnet comprises the yokes (31, 32a) which are moveable in relation to an armature (21a) and a winding (25) surrounding a part of the magnetic circuit, this armature (21a) comprised of a magnet (22a) fitted with two pole pieces (23a, 24a) projecting past both extremities of this magnet, at least one of the said pole pieces having its extremities bent at right angles in order to define the air gap inducing counter forces following a direction perpendicular to the axis of the permanent magnet (22a).A second armature (21b) identical to the first (21a) is located parallel to and facing the first. Two yokes (31; 32a, 32b) join the air gap zones of the two armatures located facing each other in such a way that the magnetic circuit constitutes a sequence of armature and yoke forming a rectangle. Two windings (25, 28) are located on opposite sides of the above-mentioned rectangle.Application primarily in the construction of electromagnets of low inertia, small volume and low leakage flux.

Abstract: The rotating or linear stepping motor comprises a permanent magnet equipped with pole pieces the ends of which define gaps.This motor comprises a second permanent magnet so that its primary has a magnet (6) equipped with pole pieces (4) and (7) and its secondary has a magnet (9) equipped with pole pieces (5) and (10). Each magnet (6), (9) is subjected to the field of a winding (2) which is perpendicular to the direction of its magnetization and directed towards one or the other of the ends of each pole piece so as to create a transfer of the flux of the magnets. In the case of a rotating motor, the winding (2) preferably has a toroidal shape with circular cross-section and the path of the flux around a circular section of winding also has an approximately circular shape so that each part of the winding (2) is surrounded by iron of minimum length. Each gap is flanked by two magnets and the residual holding torque is strengthened. This torque can be cancelled by a releasing pulse.Use of a rotating or linear stepping motor, particularly in robotics.
