The magnetic levitation thrust unit disclosed by the invention has low energy consumption and assembly cost.
Description
Technical field
The present invention relates to electromagnetic suspension technology, particularly the floating thrust unit of magnetic.
Background technology
Existing magnetic suspension advances principle such as magnetic suspension train from electromagnetic induction phenomenon, it is the principle design that utilizes " there is a natural attraction between the sexes, two like magnetic poles repel each other ", it is a kind of magnetic suspension system, utilization is installed in levitating electromagnet and the laying magnet in orbit on the bogie truck of train both sides, and the magnetic force that produces under magnetic fields makes vehicle float.The cost that this technology is made magnetic suspension train is high, and passenger capacity is little, consumes electric flux large.
Summary of the invention
The object of the present invention is to provide a kind of floating thrust unit of magnetic of less energy intensive.
Purpose of the present invention can realize like this, designs the floating thrust unit of a kind of magnetic, comprises the actuating device of permanent magnet array, nonmagnetic metal and the rotation of drive permanent magnet array; The permanent magnet group is set on the permanent magnet array, and the permanent magnet group arranges along the permanent magnet array rotation direction, and the magnetic pole of adjacent permanent magnets group is that oppositely permanent magnet array is adjacent with nonmagnetic metal not to be contacted.
The present invention is consumed energy few, and assembly cost is low.

Fig. 2 is the schematic diagram of the permanent magnet array of preferred embodiment of the present invention.
Fig. 3 is the schematic diagram of one of better implementation of an application example of the present invention.
Fig. 4 is the schematic diagram of one of better implementation of an application example of the present invention.
The specific embodiment
The invention will be further described below in conjunction with embodiment.
As shown in Figure 1, a kind of magnetic floats thrust unit, comprises permanent magnet array 5, nonmagnetic metal 18 and drives the actuating device that permanent magnet array rotates; Permanent magnet group 4 is set on the permanent magnet array 5, and permanent magnet group 4 arranges along the permanent magnet array rotation direction, and the magnetic pole of adjacent permanent magnets group be reverse, and permanent magnet array 5 and nonmagnetic metal 18 are adjacent not to be contacted.
As shown in Figure 2, every group of permanent magnet group 4 is comprised of 2 above permanent magnets, arranges perpendicular to permanent magnet array 5 rotation directions.
The velocity of rotation of described permanent magnet array 5 is more than or equal to 1000rpm.
Described nonmagnetic metal is aluminium, chromium, copper.What effect was better in the nonmagnetic metal is above-mentioned three kinds of metals.
When using, can be that permanent magnet array and actuating device are installed on the movable body, nonmagnetic metal is fixed on ground, and permanent magnet array and actuating device order about movable body and move.Also can be, permanent magnet array and actuating device fix on the ground, and nonmagnetic metal moves with respect to permanent magnet array.
As shown in Figure 1, expression almost all concentrates on the paramagnetic metal 18 by the rotating field A (unsaturation) that permanent magnet array 5 rotations produce.Make and produce upwards lift force C and propulsive force B.This magnetic suspension thrust unit can be eliminated and decide the braking force that the armature coil reaction produces permanent magnet group 4, improves the purpose that magnetic suspension advanced and saved the energy thereby reach.
As shown in Figure 3, Figure 4, embodiment is the magnetic suspension train constructional drawing that adopts a load motor of the present invention to promote.Load motor 9 (magnetic suspension train power pack section) drives to the belt pulley 22 that is looped around belt pulley 22 and drive belt 8 and array 5.When connecting alternating current for motor 9, the rotating field (unsaturation) that produces by permanent magnet array 5 rotations almost all concentrates on fixedly on the rail 18 (paramagnetic metal).Train is produced upwards to suspend and propulsive force.Rotary magnetic array 5 (rotary magnetic array portion) just is subject to the inhibition of the Ampere force that electric current produces in fixing 18 li inboards of rail.The advantage of this embodiment one rotary magnetic array aerotrain is that train and rail do not need to decide armature coil; Train only need be installed load motor and rotary permanent-magnet array, and it is low that the rail middle berth is equipped with the expense of making, and energy savings during operation suspends and propelling thrust.Numbering among the figure is described as follows: 1 wheel adapter plate, 2 horizontal wheels, 3 permanent magnetism group axis fixing plates, 4 permanent magnet groups, 5 permanent magnet arrays, 6 permanent magnetism group axis fixing plates are regulated screw mandrel, 8 drive belts, 9 load motors, 18 paramagnetic metals fixedly rail, 19 Wheel shaft, 20 vertical wheels, 21 vertical wheel adapter plates, 22 belt pulleys, 23 permanent magnetism group axles, 24 adapter plates.
As shown in Figure 3, Figure 4, the embodiment magnetic suspension train only has a load motor 9, single phase power 1.5Kw, 2, four vertical wheels 20 of 5, four horizontal wheels of 6 groups of permanent magnet arrays, article two, drive belt 8,22, paramagnetic metals of three drive pulleys are rail 18 fixedly, and then integral body is assembled.When alternating current dynamo promoted 6 groups of permanent magnet groups rotation rotating speeds and reaches 2840rpm, producing the propulsive force that upwards suspends was 10 kilograms, 7 millimeters of hoverheights.
