Abstract

1516324 Magnetically levitated transport systems G HEIDELBERG 21 July 1975 [26 July 1974 17 Oct 1974] 30453/75 Heading B7L A transport system comprises a vehicle 9 which is magnetically supported by attraction of permanent magnets 1 for movement along a track defined by a polyphase travelling field stator member 2, the air gap 4 between the stator member 2 and pole faces of the magnets 1 being controlled by spacing means. The permanent magnets are spaced by a distance related to the pitch of the polyphase stator winding in such a way that a synchronous linear motor is defined. The spacing means maintain the air gap within limits which allow the synchronous linear motor to operate so as to propel the vehicle along the track. The spacing means may be electro-magnets 5 disposed as shown on Fig. 3 adjacent the magnets 1 on side arms 10 of the vehicle 9, variation of the current in coils 8 of the electromagnets 5 being utilized to weaken or intensify the field produced by the permanent magnets. The magnets, 1, 5 are attached to the body 24 of the vehicle 9 by resilient members 11 and stabilizing arms 12; and their pole faces are covered by plate 17 which provide sliding surfaces for possible contact with further non-conductive plates 17 on the underside of the stator 2. Stator 2 comprises vertically arranged laminations of ferro-magnetic material and has slots in its underside in which is located a three-phase winding, the conductors of each phase occupying every third slot and producing a linear motor effect to propel the vehicle. For lateral guidance of the vehicle, electromagnets 13 on the vehicle co-operate with laminations 15; and guide elements 20 and 21 of which the former element is retractably mounted on the vehicle co-operate with guide blocks 18. In a modification, Fig. 7 (not shown), the electromagnets 5 are extendable and retractable relative to the permanent magnets 1 so that the mean size of the air gap 4 may be adjusted to compensate for changes in vehicle weight, it being intended to minimize current in the electromagnet by equating the lifting force of the magnets 1 to the vehicle weight. Further electromagnets (6) may be provided on the vehicle 9 above the stator 2. An alternative form of spacing means is the use of wheels which do not normally support much, if any, of the vehicle weight which is substantially borne by the permanent magnets.
