摘要： A position sensor is structurally integrated within a wide-gap magnetic actuator. Being an integral structure, the sensor provides voltages representative of a relative shift in position of the actuator's armature and pole piece from the neutral or base position and represents the actual position between pole piece and armature. Suitably the position sensor includes a photosensitive surface in the shape of a circular disk (17) that is attached to the actuator's paddle (9) and a narrow beam light source (15) which is attached to the actuator's pole piece and oriented to produce a small spot of light on the photosensitive surface.

摘要： 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.

摘要： Device for positioning a rotating body (4) movable about an axis (X-X) in relation to a stator body including a magnetic bearing (7) and a locking/releasing device (10). The device is characterized in that the locking/releasing device (10) comprises a plurality of clamps (60) with pads (61) adapted to radially grip a shaft of the rotating body. Said clamps are articulated on the stator body about axial pins (63) spaced from the rotational axis and evenly distributed in an angular manner about said rotational axis, and can be pivotally moved about said axial, by a moving control part (65) between a released configuration in which the gripping pads are at a maximum distance from the axis and a locked configuration in which the pads are at a minimum distance from the axis suitable for inducing radial clamping of the shaft.

摘要： A magnetic bearing structure is provided for supporting a rotatable member in suspended position relative to a stationary member (10) including axially spaced apart rings (22) associated with the stationary member (10), which hold a plurality of electromagnetic coils (26) circumferentially about and radially spaced from a rotatable shaft (14). At least one cylindrically shaped permanant magnet (18) surrounds a portion of the shaft (14) and is positioned generally between the pair of arcuate rings (22). The permanent magnet (18) is axially polarized and is linked magnetically to the arcuate rings (22). All magnetic flux generated by the electromagnetic coils (26) and the permanent magnet (18) is directed radially through only a pair of air gaps (16) between the shaft and the rings. Position sensors (36, 38), along with a servo control circuit (40), detect and compensate for any radial displacement of the shaft (14) to maintain it in a metastable position relative to the stationary member (10).

摘要： Rotary machine provided with a rotor having an armature of an electric radial field machine of which the design enables to absorb the radial bearing forces exerted on the rotor, and armature of an axial field machine of which the design enables to absorb the axial bearing forces exerted on the rotor. To regulate the normal forces there are provided field regulation means by the current influence in the stators of both electric machines, which means are themselves respectively divided into four quadrants with their own regulation members. The two electric machines are multipolar, each winding quadrant comprising at least two poles. The axial field machine is provided with three regulators enabling a stabilization in three degrees of freedom, the radial field machine having two regulators enabling a stabilization in two degrees of freedom.
