Abstract: A rotational actuator for the interior of an adjustable vehicle suspension damper device comprises a cylindrical permanent magnet stator and a cylindrical armature. The armature includes a shaftless winding on a non-magnetic armature frame, the armature frame extending axially beyond the winding at each end with output engaging means at one end and an opening between that end and the winding projecting radially inward across the axis of the armature. A first shaft coaxial with the armature is anchored in the one axial end of the armature frame and rotatably supported in a first axial support. A second axial support in the stator projects into the opening of the armature frame across the armature axis and supports a second shaft coaxial with the armature and extending across the opening of the second axial end of the armature frame, whereby the armature is supported at each axial end close to the winding and core while the radial size of the actuator is minimized.

Abstract: A microgeometric electric field machine includes arrays of conductors formed on or carried by a plurality of substrates. The conductors on a first group of substrates carry electrical charges, with alternate conductors being charged positively and the other conductors being charged negatively. A second group of substrates are interleaved with the first group in close proximity therewith. Also included is a voltage source for successively supplying alternate positive and negative electrical charges to the conductors of the second group of substrates. Effectively a pattern of alternate positively and negatively charged conductors is established for the second group of substrates and these patterns are caused to move, relative to the substrates, along the arrays of conductors to produce "moving" electric force fields which cause one group of substrates to move with respect to the other group.

Brushes are provided with the respective coils, and a feeder pattern arranged on an inner side of the rail, feeds electric power to the coils through the brushes, only when respective active coil parts of the coils are fully in the magnetic flux of the same direction.

Abstract: A variable magnetic reluctance generator is disclosed generally comprising a stator having pairs of spaced magnetic poles of opposite polarity. Like polarity poles are adjacent one another to define a gap having all poles of the same polarity on the same side, and permanent magnet means provide an essentially uniform magnetic field intensity along the length of the gap. The opposite polarity poles are connected by a magnetically permeable path that is surrounded by a stator winding. The rotor has alternating segments of high and low magnetic permeability and these segments move through the gap between the opposite polarity poles, which changes the magnetic permeability between them. This causes variations in the magnetic flux in the magnetically permeable path, which induces an electrical current in the surrounding stator winding. Output voltage may be controlled by auxiliary field coils on the stator or by other means.

The winding consists of several coils following one another in the direction of movement, activatable with current in cyclic sequence, which in each case are layed without overlap around a pole of at least one grooved flow guidance part which together with the permanent magnet arrangement forms an essentially even air gap, with coil axis standing perpendicular to the direction of movement. The ratio of coil interval to magnet interval amounts to 2:3. To make interfering reluctance forces ineffective, in the vicinity of the sides of the end poles lying in the direction of movement, ferromagnetic auxilliary poles are provided.

The angles .alpha. and .alpha.' are pitches between adjacent teeth of adjacent poles in the group, the angles .beta. and .beta.' are pitches between adjacent teeth on adjacent groups, having a relationship with step angle t: ##EQU1## In this relation m, n, m' and n' are integer greater than zero.

Abstract: An excitation arrangement for a long stator drive, particularly a synchronous long stator drive for rapid transit systems having combined generation of propelling and carrying forces comprises at least one heteropolar magnet which has a plurality of channels extending at right angles to the long stator direction and which are open at their pole plane lying opposite the long stator and in which magnetic coils assigned to the conductors are disposed. In order to improve the dynamic properties of the magnet, a subdivision of the magnetic coils generating the magnetic field is provided. Differing electrical behavior for slow and fast changes in the voltage driving the coil current is achieved by a tight coupling of one of the sub-coils to a short-circuit coil. Given slow changes in the drive voltage, a magnetic force resulting from the entire coil flux occurs. Given fast changes in the drive voltage, a dynamic reduction of the effective coil inductance leads to a fast current and magnetic force changes.

Abstract: A stator adapted for mounting adjacent the periphery of a moving machine gear, whereby the gear serves as a rotor in an electric alternator. A pair of elongated pole pieces are mounted in parallel adjacent the gear periphery. Dependent teeth are formed on each of the ends of each pole piece. The ends of the teeth of the pole pieces are separated from the gear tooth tips by a short air gap. The pole pieces are of length such that when the teeth at one end of a pole piece overlie gear tooth tips, the teeth at the opposite end of that pole piece overlie spaces between gear teeth. The pole pieces are displaced longitudinally relative to one another so that when the teeth at one end of one pole piece overlie gear tooth tips, the teeth at the like end of the other pole piece overlie spaces between gear teeth. Magnets are positioned between the pole pieces, one at each end. Gear motion induces electrical potentials in conductor coils wound on the pole pieces.
