A lamination bundle or stack for a long-statorlinear motor. Each lamination is made of a thin, siliconized metal sheet for the electrical industry with a thickness of between 0.35 to 1.00 mm, and at one end of its narrow side has a recess, and at its opposite end has an extension corresponding to this recess for a positive or form-locking arrangement of the bundles in rows adjacent to each other. Of the teeth laterally defining the grooves for cable windings each end tooth has a width which corresponds to half the width of the adjacent tooth and at its free end is cut at an incline, whereby the inclined cutting line extends from the groove to the end of the narrow side. The laminations are stacked so as to completely cover each other, and have their contacting surfaces glued together over the entire surface area thereof. According to the method of producing the laminated bundle, a thin strip of sheet metal for the electrical industry, coated on both sides with a duroplastic adhesive and unwound from a drum, is fed by a feeding or advancing device to a punch; thereupon, these laminations are punched out from the metal sheet, are subsequently stacked upon each other in a magazine, and are adhesively joined with each other into a bundle or packet; thereafter, the laminated bundle of laminations is first conveyed through different thermal treatment zones arranged one after the other, and is subsequently supplied to a device for coating the bundle of laminations with a corrosion protective layer.

A magnetic suspension for a railway vehicle with electromagnetic carrying, guiding and driving gear, wherein the forces of the exciter and transverse flux magnets support, guide, drive and brake together with an active motor section by regulating the gap distance from a track-side reaction rail measured by gap, measured by gap sensors, and wherein the vehicle includes hover frames and the magnets are resiliently mounted to the hover frames in such a way that both supporting and guiding magnets as well as the carrying magnets of the two longsides of the vehicles are separated from each other as to action and the hover frames are coupled to the vehicle superstructure through spring means is disclosed. Each magnet includes at least four coils and the transvers flux magnets have adjacent coils with coil lengths selected so that within the magnet coil peripheries of the adjacent coils, lying side by side, do not coincide. The coils of the magnets are divided into two identical groups and the coils of each group are distributed over the total length of the magnets so as to supply the torques required for stabilization of the pitch movement of the vehicle. The coils of each group are operable responsive to an autonomous gap control loop. The supporting and guiding magnets have glide skids for limiting the free motion play in the vertical and horizontal directions relative to the track to a predetermined gap deviation to be expected in service.

Magnetic suspension railway

An apparatus for damping mechanical oscillations vibrations or pulstations with magnetic suspension railways having vehicles movable to float along elevated tracks using magnetic levitation or suspension technique as well as having supplemental suppression device suppression devices to eliminate oscillation. Each supplemental oscillation suppression device has an additional mass in the form of a hollow body or solid material, and is suspended by means of steel or rubber springs on the longitudinal vehicle support or on the longitudinal track beam. One end face of that supplemental oscillation suppression device associated with the vehicle is provided with a buffer in the horizontal plane of the longitudinal axis thereof, and respective stops are arranged on both longitudinal sides and are fastened to the longitudinal support, with the end face of the hollow body facing the buffer being closed by a base plate, the opposite end face being tightly closable with a screw cap. That supplemental oscillation suppression device associated with the track is fastened in a free-swinging manner within the box profile of the longitudinal track beam and on the top chord thereof. The web plates are provided with openings for inserting the supplemental oscillation suppression device.

The stator of a linear motor is comprised of a core having many parallel grooves; three cables are preassembled so that rungs of a ladder-like configuration can be laid into the grooves. The cables have, individually, a meandering configuration, and overlapping loops are tied together. The cables each have a semiconductive layer for shielding, i.e., insulation sheathings that include conductive additives. Bare wires are strung along the assembly and clamped onto the cables to electrically interconnect the shields as well as different points of the same shield for grounding.

Polyphase stator system for a linear motor

The stator of a linear motor is assembled by separately assembling the windings as a uniform configuration, using a dummy to place cables into requisite positions and tieing the resulting coil ends together by end elements. The dummy is of an endless belt variety and is used to assemble the stator winding configuration in endless type fashion. The resulting assembly is placed into the stator core or cores which have been placed along the contemplated track part along which the motor is to move a vehicle or the like, carrying the armature of the motor.
