Abstract
The utility model discloses a permanent magnet and electromagnet mixed magnetic suspension device, which comprises a permanent magnet, a displacement sensor, a suspensoid, an electromagnet, a controller, a base seat, and a support. The displacement sensor and the permanent magnet are arranged on the support, the electromagnet is arranged on the base seat. The utility model has the advantages that the structure is simple, the energy source is saved, and the technology is advanced. The mixed magnetic suspension device is a pioneering high-tech product, and can be widely applied to teaching appliances for demonstrating, toys, advertising devices, and high-tech exhibiting products, etc.
Description
The utility model relates to a kind of magnetic levitation system, belongs to the magnetic levitation technology field.
As everyone knows, magnet is attractive for ferromagnetic object.Utilizing this attraction, make object contactless and stably be suspended in the air by automatic control again, is the suction type magnetic levitation technology.This technology is be most widely used in the magnetic levitation technology a kind of, is mainly used at present on the magnetic suspension bearing, has and do not have friction, rotating speed height, operates steadily, hangs down characteristics such as maintenance, and is very popular.What present suction type magnetic suspension was mainly adopted is that the controlled electromagnet of simple dependence is realized the freedom of object, the active suction type magnetic levitation technology that stably suspends for the suction of object.Adopt the shortcoming of this mode to be, because the magnetic flux density of electromagnet is directly proportional with electric current, during little electric current, its load capacity is subjected to the restriction of electric current, and electric current not only can cause the increase of coil heating amount greatly, also can cause the increase of energy consumption.And the mixing suction type magnetic suspension of adopting permanent magnet to combine with electromagnet just can make most of load be born by the permanent magnet that does not need external energy, thereby reduce the burden of electromagnet, like this, not only reduce the caloric value of electromagnet, and saved the energy, increased load capacity again.
The purpose of this utility model is to provide a kind of simple in structure, advanced technology, energy savings and the strong magnetic levitation system of load capacity.This magnetic levitation system both can be used as demonstration teaching aid, also can be used as toy for children or high-tech displaying etc.
For achieving the above object, the utility model is to adopt following proposal to realize:
The utility model comprises position transducer, permanent magnet, suspended substance, electromagnet, control circuit, base, support.Transducer and permanent magnet are rack-mount, and electromagnet is installed on the base.The input of the output connection control circuit of position transducer, the output of control circuit connects the input of power amplifier, the variation of control power amplifier output, the size of the output control electromagnet coil current of power amplifier, suspended substance is ferromagnetic material or the object that contains ferromagnetic material.
Operation principle of the present utility model is as follows: employing can place the top of suspended substance to the permanent magnet of suspended substance generation greater than the permanent magnetism power of suspension gravity, and like this, permanent magnet just has an attraction that makes progress to suspended substance; And electromagnet is placed the below of suspended substance, after the energising, electromagnet just has a downward attraction to suspended substance.When permanent-magnet attractive power and electromagnetic attraction make a concerted effort to equate with the gravity of suspended substance the time, suspended substance just can be suspended in the air.Sensor monitors suspended substance on the support and the air gap between the permanent magnet change, and output signal forms control signal after treatment to control circuit, regulate the coil current of electromagnet automatically, thereby change electromagnetic attraction, make suspended substance realize that free and stable ground suspends.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a control section circuit diagram of the present utility model.
See accompanying drawing 1, the utility model comprises position transducer 1, permanent magnet 2, suspended substance 3, electromagnet 4, controller 5, base 6, support 7.Described base 6 is provided with support 7 and electromagnet 4, the top of support 7 is provided with permanent magnet 2 and position transducer 1, electromagnet 4 be positioned at permanent magnet 2 under, the equilbrium position of suspended substance 3 is located between electromagnet 4 and the permanent magnet 2, the output of position transducer 1 connects controller 5 inputs, and the output of controller 5 connects electromagnet, and the control signal of controller 5 outputs is amplified by power amplifier, control electromagnet 4 produces electromagnetic force, and controller 5 is installed in the base.
Operation principle of the present utility model is as follows: referring to Fig. 1,2, detect variable in distance between suspended substance 3 and the permanent magnet 4 by position transducer 1, its output signal is delivered to the long-pending differential circuit of being made up of W1, W2 and W3 and peripheral circuit thereof, exports the ID signal.The proportional component that is made of operational amplifier W4 and peripheral circuit thereof obtains scaling signal, behind the feedback circuit that this scaling signal is formed through the comparison circuit be made up of operational amplifier UIA and peripheral circuit thereof with by operational amplifier UIB and peripheral circuit thereof, input to the PWM pulse-width modulation circuit that constitutes by 3525 chips and peripheral circuit thereof, after analog signal changed into digital signal, behind isolating transformer and filter circuit, export the close power amplifier circuit to, as the driving of high-power MOS tube IRFP450.What close power amplifier adopted is the half-bridge switch power amplifier that is made of IRFP450 and peripheral circuit thereof, and the output of close power amplifier is through filtering, and the size of electric current produces corresponding electromagnetic attraction in control electromagnet 4 coils, makes the suspended substance stable suspersion.
In sum, the utlity model has simple in structure, advanced technology, energy savings, strong, the widely used characteristics of load capacity, not only can be used as demonstration teaching aid, also can be used for advertising device, urban landmark thing, toy and high-tech displaying etc.
