Detailed description of the invention
Being described in further detail the purpose of the present invention below by specific embodiment, embodiment can not at this one by one
Repeat, but the most therefore embodiments of the present invention are defined in following example.
Embodiment
As shown in Figures 1 to 5, a kind of Electromagnetic Control screw rod accelerator, including:
Field generator for magnetic 1, is used for producing alternating magnetic field, and inside includes silicon sheet core 5 and is wound in described silicon sheet core 5
The winding 6 of inner side；
Screw rod 4, is arranged in described field generator for magnetic 1 along axis, for the rotary speed of accelerated body 3 being converted into axially
Point-to-point speed；
Accelerated body 3, is matched with described screw rod 4 by female thread, and its periphery wall is symmetrically arranged with two pieces of contrary neodymiums of magnetic level
Ferrum boron permanent magnet 2；
Input power device, including the big merit being sequentially connected between one-way communication power supply and field generator for magnetic 1 by circuit
Rate inverter 10, power consumption instrument 12, regulate for realizing the rotary speed in magnetic field by adjusting input AC electricity frequency.
Specifically, as in figure 2 it is shown, the silicon sheet core 5 of described field generator for magnetic 1 is cylindrically, loads magnetic field and send out
In generating apparatus 1, it is a part for motor main flux magnetic circuit.Being lost to reduce silicon sheet core 5, it is to be by thickness
Compress with the stalloy closed assembly of insullac insulation between 0.5mm, sheet and form.Silicon sheet core 5 circumferential inner surface has uniformly vertically
The straight trough of distribution.
Specifically, as it is shown on figure 3, described winding 6 is divided into main winding 7 and starts winding 8, due to the single phase ac of input
Electricity can not produce rotating excitation field, in parallel plus a starting winding 8 in a device, starts winding 8 and to concatenate one suitable point
Phase electric capacity 9 so that approximate in phase place with the electric current of main winding 7 and differ 90 degree.Two such differs the electricity of 90 degree in time
Circulate into two spatially difference windings 6 of 90 degree, it will spatially generation (biphase) rotating excitation field, at this rotary magnetic
Under field action, drive the rotation of accelerated body 3.Wherein it is noted that several square coils of same coil groups, by same center
Position be embedded in one by one and be arranged in three-back-shaped pattern.In order to increase area of dissipation, described silicon sheet core 5 is at adjacent winding
It is provided with space between 6 and forms the air duct 51 for heat radiation.
As shown in Figure 4, the Nd-Fe-B permanent magnets 2 that two pieces of magnetic levels of described accelerated body 3 lateral symmetry placement are contrary can be complete
Become the effect of its stress.Neodymium iron boron as rare earth permanent-magnetic material, have high magnetic energy product and coercivity, high-energy-density excellent
Point.Induced field stress in field generator for magnetic 1, and by being embedded in accelerated body 3 the two poles of the earth, drive accelerated body 3 to occur
Rotate.Wherein it is noted that two Nd-Fe-B permanent magnets 2 are disposing when, two magnets must assure that opposing polarities ensures magnetic
On the contrary, thus ensure that overall magnetic flux line completely passes through.Female thread 11 coordinates screw rod 4, to axial-rotation is converted into axial straight line
Motion plays an important role.Female thread 11 needs to keep equal with external screw rod thread pitch, and lead angle Ψ is equal, rotation direction phase
With.Accelerated body more than 3 uses material to elect PTFE wear-resistant plastic as, and the impact strength of Wear-resistant plastic flitch is high, and coefficient of friction is at 0.07-
Between 0.11, close to zero friction.There is resistance to chemical corrosion, can the dielectric corrosion such as acid and alkali resistance, salt.
Described screw rod 4 is mainly responsible for axial-rotation is converted into axial linear movement.Described screw rod 4 uses 7075 aluminium alloys
Material makes, and aluminium alloy density is low, but strength ratio is higher, it is adaptable under this operating environment, runs up, intensity is high, diamagnetism
Working environment.Its wearability and corrosion resistant is strengthened by certain hard anodising or incorporating of surface spraying titanium alloy material
Erosion property.
Described high-power inverter 10 uses WL3688B high-power inverter, described power consumption instrument 12 to use WL258 power consumption
Instrument.
As it is shown in figure 5, for the rotary speed regulating magnetic field, the most direct way is exactly directly to change its input AC electricity
Frequency carries out speed governing.Converter plant for alternating current can utilize high power AC inverter to complete, high-power inverter 10
First alternating current is become unidirectional current, then with electronic component, unidirectional current is switched, utilize controllable silicon, if a Frequency Adjustable
The device of rate, makes frequency the most adjustable, becomes alternating current.By the generation magnetic field of field generator for magnetic 1 periodically
Change directly affects magnetic field rotating speed, so that the revolution of accelerated body 3 is adjustable in certain scope.Principal set up parameter
Relevant with screw rod 4 angle of climb and effective acceleration distance.By the directly monitoring of power consumption instrument 12, single unit system can be obtained intuitively
Power consumption parameter, can carry out in respective range effective and safe ground regulation.
The present embodiment provides the nonmagnetic accelerated body 3 of a two-pole device Nd-Fe-B permanent magnet 2 and with certain helical angle
Rotate accessory based on the screw rod 4 risen, be applied through the alternating current input that high-power inverter 10 processes simultaneously in the external world
Alternate rotary magnetic field generating means 1 produce rotate magnetic field.After outer driving magnetic field rotates and starts to produce phase contrast,
Accelerated body 3 changes with the magnetic pole relative rotation a of outer driving magnetic field.Magnetic field rotating speed produced by field generator for magnetic 1
Degree is gradually increased, and produces Magnetic driving power, when driving moment is more than under the effect that Nd-Fe-B permanent magnet 2 like pole is attracted each other
Accelerated body 3 is under working environment during the most produced static friction force square, and accelerated body 3 starts rotation.In accelerated body 3
Portion is with female thread 11, and accelerated body 3 female thread 11 coordinates with screw rod 4, makes accelerated body 3 along orbital mirrors as rotating
It is space rate axially by translating rotation axial for a part simultaneously, reaches the purpose accelerating to launch.By adjusting magnetic
Field rotary speed and direction, adjust speed controlling and the location of accelerated body 3.
The above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not to the present invention
The restriction of embodiment.For those of ordinary skill in the field, can also make on the basis of the above description
The change of other multi-form or variation.Here without also cannot all of embodiment be given exhaustive.All the present invention's
Any amendment, equivalent and the improvement etc. made within spirit and principle, should be included in the protection of the claims in the present invention
Within the scope of.
