Abstract
A magnetic suspension type of linear superconductor motor features that its main body is riding on a quasi-rail and is composed of external casing, shielding cover in the casing, two suspended electromagnets horizontally connected inside the lower opening of shielding cover and running electromagnets connected inside the upper part of shielding cover. Its advantages include use of quasi-rail, electrodynamic suspension, no magnetic cushion, monopolar linear running mechanism, no environmental pollution and excellent speed regulation. It can be used for magnetic suspension train, mining car, subway, etc.
Description
The present invention relates to a kind of magnetic suspension linear motor.
Known magnetic suspension linear motor has aspiration-type magnetic pad and two kinds of forms of repulsion formula magnetic pad, is made up of motor body and rail two parts.Japan ML-500 type single track superconduction magnetcisuspension motor, rail whole process is wound with and suspends with coil and propelling property coil, is called coil on the ground.Or instead go up coil as magnetic field, ground with the Nd-Fe-B permanent magnetic rail, adopt super electricity to lead induction repulsion type magnetic pad and drive by linear synchronized motor.World's magnetic levitaion motor in vogue mostly is the normal electric conductive magnetism attraction type magnetic pad of single track straddle-type at present, drive by linear induction motor, and the structure heaviness, the project cost height moves uneconomical.(list of references: " Electrical Engineer's handbook, 12 pages of specific type of electric machine cars of 23 pieces of chapter 1, China Machine Press, 95 years versions.)
The objective of the invention is to provide a kind of superconducting rail magnetic suspension linear motor, and it is simple in structure, and project cost is low, and is energy-efficient.
The object of the present invention is achieved like this: motor body straddles on the standard gauge, and this volume surrounding is a casing, is radome in the casing, and the inboard level of radome end opening connects two levitating electromagnets, and it is inboard that the operation electromagnet is connected the radome top.
The present invention adopts standard gauge, and electric power suspends, no magnetic pad, and one pole straight line running mechanism, but AC/DC in principle, and the induced current in the track can be drawn for ground warning signal device and use.Cooperate existing track circuit automatic block equipment, move safer.And expenditure of construction is low, and operating cost is few, and non-environmental-pollution, convenient operating maintenance, and speed adjusting performance is excellent, can use for magnetic suspension train, industrial-mineral electric locomotive, city underground, belt orbit motor car.
Elaborate below in conjunction with drawings and Examples.
Fig. 1 is a structure chart of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to view.
The 1. main floating utmost points among the figure, 2. help the floating utmost point, 3. superconduction lift coil, 4. casing, 5. radome, 6. powered coil, 7. superconduction magnetizing coil, 8. operation electromagnet, 9. standard gauge.
In Fig. 1 and Fig. 2, casing (4) is curved by two blocks of homogeneous sheet metals, is fixed by bolts to the outside of radome (5).
Radome (5) is the skeleton of motor body, held concurrently magnetic conduction and magnetic screening action.Select for use the splendid amorphous alloy of magnetic property repeatedly to be pressed into " " font.
Two levitating electromagnets, symmetrical level is installed in the inboard of radome end opening, floats the utmost point (1) and helps the floating utmost point (2) to constitute by main.Lead, help the floating utmost point to be rectangle, repeatedly be pressed into high magnetic conduction non-crystaline amorphous metal, an end is equipped with pole shoe.Pole shoe is made with the magnetic temperature compensating alloy material.Help floating pole shoe thinner, stalk is far away slightly from the road.Main, help floating extremely whole embed superconduction lift coil (3) after, clog with non magnetic slot wedge, use bolted again on radome (5).
Operation electromagnet (8) also repeatedly is pressed into rectangle by high magnetic conduction amorphous alloy, and an end has the semi-closed port shallow slot.Pole shoe is coil holder, looses in the semi-closed port shallow slot to embed powered coil (6), with non magnetic slot wedge filling.Put in order embedding superconduction magnetizing coil (7) then, be fixed by bolts to the interior top of radome (5) again.
Standard gauge (9) adopts the little high-quality steel rolling of magnetic deformation.
Operation: fill direct current to the floating electromagnet of plucked instrument, the magnetic flux flow that the main floating utmost point (1) sends is through standard gauge, with road stalk magnetization, under the attraction of the repulsion effect that helps the floating utmost point (2) and the main floating utmost point (1), motor body is lifted, give operation electromagnet (8) charging, the magnetic flux that superconduction magnetizing coil (7) sends passes to standard gauge (9) through levitating electromagnet with magnetic field energy.One side helps floating to levitating electromagnet guarantor magnetic, on the other hand, form uniform magnetic field between operation electromagnet (8) and road stalk upper surface.Working edge is subjected to the effect of directed electromagnetic force in powered coil (6) groove under the effect of electromagnetic field, promotes the motor body operation.Simultaneously, electromagnetic field has induced electromotive force to generate on standard gauge (9) surface, draws the ground warning signal device power supply of back to motor operation 1.5 kilometers places, the place ahead, blows a whistle and warns, and matching track circuit automatic block signal is guaranteed security of operation again.
