Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
A kind of small-sized active Magnetic levitation apparatus, including the magnet exciting coil 2 of energising, institute outside soft magnetism bead 1 and soft magnetism bead
The radius stating magnet exciting coil is more than the little radius of a ball of soft magnetism, and magnet exciting coil 2 covers on soft magnetism bead 1 periphery, described soft magnetism bead 1 quilt
The magnet exciting coil 2 of energising magnetizes.After coil electricity, as shown in Figure 1, Figure 2, it is assumed that electric current excites the magnetic field to be, upper N pole, lower S pole no matter
It is identical with coil magnetic field all the time the most how bead rotates its direction of magnetization.
Be externally provided with hemispherical shell permanent magnet 3 at magnet exciting coil, the magnetic field of permanent magnet of described hemispherical shell permanent magnet 3 with
In soft magnetism bead 1 magnetizes rear space, magnetic flux density is same or like, prevent soft magnetism bead by permanent magnet magnetization, and described hemisphere
The coercivity that shelly permanent magnet tool is higher.
Described magnet exciting coil 2 connects has direction-control apparatus, described direction-control apparatus to include central control system 6, move
Power apparatus 5 and attachment means 4, described attachment means 4 one end connects magnet exciting coil 2, one end is connected with power set 5, dynamic
Under the driving of power apparatus 5 controls, attachment means 4 moves thus adjusts the direction that magnet exciting coil tilts.
Magnet exciting coil tilts certain angle, and the magnetized direction of soft magnetism bead changes with magnet exciting coil, now bead
Being produced couple by the repulsion of magnetic field of permanent magnet and the effect of captivation, bead is started to rotate by force couple role.Coil is to difference
Direction tilt, then bead rotates to corresponding direction therewith.
Equipped with pressure transducer on soft magnetism bead, signal is passed to central control system by described pressure transducer.Described
Power set be motor, described central control system is single-chip microcomputer, described attachment means be connect magnet exciting coil several
Mechanical arm.
If system is placed in plane, by frictional force effect, the rotation of bead is converted into translation and is subjected to displacement, and therefore should
System can use as the universal wheel of maneuverability.If system is inverted (placing being considered as forward in Fig. 3), permanent magnet is fixing not
Dynamic, coil can tilt to any direction, bead by magnetic levitation in permanent magnet cavity.Bead is loaded onto various sensor,
Such as pressure transducer.System is amplified, it is assumed that system is embedded in underground, only exposes the fraction convex surface of bead, and people stands on spheroid,
The size of pressure transducer discernment and direction, when human body makes the action walked to all directions or jump, sensor will be subject to
Force information is sent in the system of control coil make coil tilt to corresponding direction, and spheroid starts to rotate, can less space
The action effect of the interior simulation human body various motions in real world, it is achieved virtual displacement and do not limited by direction.
Small-sized active magnetic suspension, i.e. without the magnetic suspension movement under board pattern, or can be used for private car, reduces system and runs
Cost, promotes civilian popularizing, breaks the barrier of the mobility of magnetic levitation technology.
This utility model utilizes Magnetizing mechanism to confront with each other, and makes ferromagnetic bead resist permanent magnetism after magnet exciting coil preferential magnetization
The magnetization of body, thus produce the magnetic pressure driving force as equipment, it is effectively utilized in soft magnetism outside magnetic field and does transient change
Character, it is ensured that the stability of its overall operation.
The above, be only preferred embodiment of the present utility model, and this utility model is not made any pro forma limit
System, any those skilled in the art, in the range of without departing from technical solutions of the utility model, according to of the present utility model
Technical spirit, any simple amendment that above example is made, equivalent and improvement etc., all still fall within this utility model
Within the protection domain of technical scheme.
