摘要： PURPOSE:To suppress the temperature rise of a current collecting coil to a low level by constituting the coil by laminating multiple insulated braided wires formed of multiple insulated strands in a fat square shape having the width corresponding to the winding width of the coil. CONSTITUTION:An insulated braided wire 21 formed by braiding multiple insulated strands 21a having insulating sheaths is formed in a flat square shape having the width corresponding to the winding width of a coil 24. Then a formed braided wire 23 is formed by winding an insulting tape 22 around the outer periphery of the wire 21. Thereafter, the coil 24 is formed by winding the formed braided wire 23 around a spool in multiple layers. After removing the coil 24 front the spool and forming the removed coil 24, the coil 24 is insulated by successively winding an insulating tape 25 and glass tape 26 around the outer periphery coil 24. Then an inductive current collecting coil 28 using a sheath 27 as an insulating layer to the earth is formed by housing the coils 24 in a metallic mold and forming the sheath 27 of a prescribed resin. Therefore, the temperature rise of the coil 28 can be suppressed to a low level without increasing the size of the coil 28 by reducing the current per unit area.

摘要： PURPOSE:To suppress the electromagnetic force of a pickup coil for inductive current collection being applied to a supporting member. CONSTITUTION:Levitation coils 4, 5, each comprising a pair of vertical coils subjected to null flux connection, are disposed on the side wall 3 of ground track and a pickup coil 7 for inductive current collection is disposed oppositely to any one levitation coil on the car body 1 side. A supporting member 9 on the car body 1 is provided with a coil fixing plate 10 fixed with a three-phase pickup coil 7. Since the electromagnetic force of the pickup coil 7 being applied to the supporting member can be suppressed, rigidity of the supporting member can be lowered.

摘要： PURPOSE:To conduct stable travelling by installing superconducting coils for stabilization oppositely faced to both of a pair of upper and lower sidewall coils for levitation, which are null-flux connected mutually, onto a track sidewall on the ground side apart from a superconducting coil for collecting currents. CONSTITUTION:Upper-side sidewall levitation coils 4 and lower-side sidewall levitation coils 5 are connected in a null-flux manner on the inside of sideswalls 3 on both sides forming a track 2 on the ground side. A plurality of coils 6, 7 for collecting currents are disposed onto a car body 1 while being oppositely faced to the sidewall levitation coils 4 and 5 in the longitudinal direction. Superconducting coils 9 for stabilization are mounted on both side sections of the car body, and housed in a cryostat 10 together with the superconducting coils 6 for collecting currents. The superconducting coils 9 for stabilization are faced oppositely to the upper and lower sidewall levitation coils 4 and 5. Accordingly, a change in the vertical direction of the car body 1 is inhibited, thus carrying out stable travelling.

摘要： PURPOSE:To suppress influence of an eddy current loss in an inner tank due to an inner invasion magnetic flux and to reduce loss in an inner tank based on relative vibration to an outer tank and a superconducting coil of a heat shield by setting resistivity of the shield to a predetermined range. CONSTITUTION:Resistivity of a heat shield 2 is set to a range 20-70muOMEGAcm (corresponding to 4mm of a thickness), i. e., in which an eddy current loss of a refrigerant storage inner tank 3 due to inner invasion magnetic flux due to a harmonic magnetic field. does mot make much increase. Thus the electric resistance of the shield 2 is raised to reduce an eddy current due to a relative vibration of the shield 2 and a superconducting coil 4 of an outer tank 1, thereby effectively reducing a loss in the tank 3 due to reaction. Thus, a refrigerant evaporating amount is reduced, a decrease in refrigerant cooling efficiency is prevented, and superconducting damage can be prevented.

摘要： PURPOSE:To simplify the structure of a mold and obviate mold releasing work by containing a coil in a mold buried in a concrete block and having conductivity and pouring synthetic resin into the mold for forming the coil and mold in a body. CONSTITUTION:A mold 11, comprising a thin plate formed by a press machine or the like so that the top face is opened, is buried in a concrete block 3, and an on-ground coil 1 is formed in a body with the coil 1a, contained in the mold 11, by pouring synthetic resin 1b into the mold 11. In the next step, a conductive layer 13 is applied only to the surface of the coil 1, which is faced to the opening face of the mold 11, and the layer 13 is made to electrically contact with the mold 11 for making the entire surface of the coil 1 equipotential. In addition, the formation of the coil 1 and the integral formation with the block 3 are simultaneously conducted. Therefore, the structure of the mold itself can be simplified and mold releasing work can also be obviated.

摘要： PURPOSE:To improve cooling efficiency of a stator, by a method wherein refrigerant is circulated between a heat exchanger and a refrigerant reservoir utilizing rotational force of an axle, and heat is radiated in the open air. CONSTITUTION:A stator 20 of a linear motor is constituted by a coil 1a and a core 1b of a silicon steel plate. A beam 1e serves as reinforcement of the core 1b and also carries the rotor 20 to an axle 2 of a wheel 3. An end portion of the coil 1a is protected by a protective cover 1d. In this case, a refrigerant reservoir 6 mounted in close contact state to a rear surface of the core 1b for storing water, for example, as a refrigerant 10, an impeller 7 of refrigerant feed means installed to the axle 2 for discharging the refrigerant 10 from the refrigerant reservoir 6, and a heat exchanger 9 are provided. Then heat produced from the core 1b and the coil 1a is transmitted to the refrigerant 10 in the refrigerant reservoir 6, and the refrigerant 10 is fed to the heat exchanger 9 by the impeller 7 thereby the transmitted heat is radiated to the open air.
