    Abstract: A torque motor (8) comprises an armature (30) placed radially between a central bar (31) and an external ferromagnetic tubular portion (32). The central bar (31) comprises two portions of the same cylinder (33A, 33B) diametrically opposite each other and having substantially equal angular amplitudes below 180°, and separated by generally parallel longitudinal flats (34A, 34B). A radial permanent bar magnet (35) is incorporated in the central bar (31) between the cylinder portions (33A, 33B). The armature (30) has a winding (36) formed from longitudinal strands (36A) connected by transverse strands (36B) and arranged into bundles (F1, F2) within which all currents flow in the same direction at all times.

    Abstract: PROBLEM TO BE SOLVED: To provide a simply structured rotor locking/unlocking device applicable to a locking/unlocking operation repeated frequently. SOLUTION: A rotor B is provided with an annular flange 1 extending across an axial line Z-Z, while a stator A is provided with a stationary annular supporting face 2 and a movable annular supporting face 3 axially facing the flange 1 on both sides of the flange 1. The movable annular supporting face 3 is formed in a thrust ring 4 connected radially to a stator pat 5. The thrust ring 4 moves between an unlocking position and a locking position by an action of an annular air bag 6 arranged between a stator back face 7 and the thrust ring 4 inside the stator part 5. In the unlocking position, both annular supporting faces 2, 3 are arranged separately from each other, so that the rotor B is freely rotated and moved in the radial/axial direction. In the locking position, the movable annular supporting face 3 is pressed axially toward the stationary annular supporting face 2, so that the flange 1 is held fixedly.

    Abstract: Un palier magnétique rotatif à 1-axe actif comporte: une première portion comportant, autour d'un axe de rotation, deux pièces polaires annulaires radialement externe (23) et interne (24) et un aimant annulaire à aimantation permanente (25) interposé entre une première portion polaire de liaison solidaire de la pièce polaire annulaire radialement externe et une seconde portion polaire de liaison solidaire de la pièce polaire annulaire radialement interne; une seconde portion comportant deux pièces polaires annulaires de fermeture (26, 27) disposées axialement de part et d'autre de la première portion, et comportant des tranches annulaires (26A, 27A) disposées axialement en regard des pièces polaires annulaires au travers d'entrefers annulaires. L'aimant annulaire (25) est à aimantation axiale, et les première et seconde portions polaires de liaison (23A, 24A) entre lesquelles l'aimant permanent est interposé sont disposées transversalement à l'axe.

    Abstract: A rotor (B) is centred with respect to a stator (A) by means of a magnetic bearing (10) active on an axis parallel to the reference axis (Z-Z), and two magnetic centring devices (20,30). An electromagnetic motor (40) controlling the movement of the rotor is arranged radially outside the bearing and axially between the centring devices. The stator has pairs of pole pieces (11',11";12',12") on either side of the axis, with magnets (13,14) magnetised radially in opposite directions between them. The rotor has two U-section pole pairs (15',15";16',16") on opposite sides of these with air gaps. Coils (17,18) are supplied from a radial centring servo circuit (19) connected to a position, velocity or acceleration sensor (19S).
