    摘要: The vehicle is powered by a linear synchronous motor, The linear synchronous motor comprises a series of field poles fitted on the vehicle body along its total length and a series of magnetic devices being provided along a track on the ground facing these field poles and developing a travelling magnetic field. A driving force developed between these field poles and the magnetic devices causes the vehicle to move.Such a linear synchronous motor powered vehicle has a problem when securing proper and satisfactory places to mount the necessary equipment of the vehicle. The problem arises from the peculiar construction thereof that a plurality of field poles are disposed along the entire length of the vehicle body.A satisfactory mounting of the apparatus may be attained by a unique arrangement of the field poles, without making the vehicle body large in size or providing discomfort to the passengers.

    摘要: A rapid transit system in which a vehicle, typically comprising a train of detachably coupled cars, is suspended in an underground vacuum tunnel by permanent magnetic rails of high coercivity and propelled by gravity. For closely spaced stations, such as in urban areas, the connecting tunnel paths are smooth continuous curves, lying essentially in the vertical planes connecting adjacent stations. For widely separated stations, such as in inter-city transit systems, the tunnel paths have horizontal reaches at their maximum depth, joined at the ends by smooth paths which arc up towards each station. The magnetic suspension and the vacuum environment enables the vehicle to move frictionlessly at high speeds without contacting the rails or any other part of the tunnel. Gravity propulsion from one station to the next is accomplished by allowing the vehicle to move frictionlessly down the decending arc of the tunnel, during which time it is accelerated by gravity, and decelerating by gravitational braking while moving along the tunnel's ascending arc. Thus, the trip is accomplished by transforming the vehicle's gravitational potential energy into kinetic energy and back into gravitational potential energy. Excess kinetic energy arising from moving between stations having different elevations is supplied or absorbed by onboard linear motor/generators that provide supplementary propulsion or regenerative braking. These linear motor/generators draw and return energy to on-board flywheel energy storage units. While moving along very long straight tunnel paths the vehicle's gravitational coasting speed is boosted by flywheel energy which is recovered by regenerative braking. Since the motion is essentially without friction and since the linear motor/generator-flywheel motor/alternator system can be designed with very high efficiencies, the principle of conservation of energy applies and very little input energy is required. In the ideal case, no input energy would be required since the vehicle's total energy remains constant even while moving between two stations at high speed. When the vehicle is at rest at stations having different elevations, the differences in its gravitational potential energy are balanced essentially by equal differences in its stored flywheel inertial energy. Except for a small amount of electrical energy expended for life support systems and to make up for losses due to energy conversion inefficiences, no energy is used or required for the actual trips between stations.

    摘要: A magnetic thrust bearing (110) comprises a magnet (112) mounted on a shaft (114) and a plurality of equi-angularly spaced superconductors (116) mounted on a static structure (118). Each superconductor (116) is mounted onto the static structure (118) by a parallel hinge strip (120) which allows the superconductor (116) to move radially relative to the axis of rotation of the shaft (114). The radial movement of the superconductors (116) changes the cross-sectional area of the magnetic field between the magnet and the superconductors (116) and this changes the stiffness of the magnetic bearing (110). The superconductors (116) move radially due to the pivoting of the parallel hinge strips (120) due to changes in the loads acting on the magnetic bearing (110). It is possible to detect movement of the shaft and to actively move the superconductors to control the stiffness of the magnetic bearing and to control the clearance in the magnetic bearing as in FIG. 5.

    摘要: A high speed ground transportation system, is suspended in an underground vacuum tube by a frictionless magnetic suspension system and propelled by gravity. The tubes are suspended inside deep underground tunnels from anchor points near each adjacent station and follow smooth catenary curves similar to the main suspension cables of a suspension bridge. Gravity propulsion is accomplished by allowing the vehicle to coast down the descending arc of the tube, during which time it is accelerated by gravity, and decelerating by gravitational braking while coasting up the tube's ascending arc. Thus, the trip is accomplished by transforming the vehicle's gravitational potential energy at one station into kinetic energy and back into gravitational potential energy at the next station. Excess kinetic energy arising from coasting between stations having different elevations is supplied or absorbed by on-board linear motor/generators that provide supplementary propulsion or regenerative braking. These linear motor/generators draw and return energy to an on-board flywheel kinetic energy storage system. Passenger and cargo transfer between the vehicle's interior and station is made without removing the vacuum environment of the vehicle, by providing air-locks through the tube walls at the station.

    摘要: The motor has a passive conductive track, comprising an inductor winding intended to be traversed by a direct current, of superconducting material, placed in a cryostat, rotary with the cryostat around an axis parallel to theplane of the track and perpendicular to the direction of relative movement of the track and of the inductor. An auxiliary polyphase winding parallel to the track and wound so as to create a sliding field, synchronous with the field of the inductor, is arranged mechanically so that relative motion between it and the axis of the inductor in translation along the track is absent. The auxiliary polyphase winding may be flat and comprise coils whose separation increases from its medium plane, in line with the axis of the inductor.

    摘要: The linear synchronous motor under consideration is used for propelling a magnetically levitated vehicle along a track, the field coils of the motor being carried on the vehicle while the driving coils are disposed along the track. During running of the vehicle, it is possible that a vibration may occur due to attraction and repulsion between the driving and field coils, thereby impairing smooth and stable running of the vehicle. In order to reduce the abovementioned vibration, the dimensions of the driving and field coils and the average distance between the driving and field coils are chosen so that a specific correlation is maintained between them.
