Description

The full-balance power motor

Technical field

The present invention relates to a kind of structure of power motor, particularly a kind of structure kenel of being derived with balance linkage disequilibrium theory of adopting is used the high efficiency full-balance power motor that obtains that rotating speed is fast, torsion big and can save the energy.

Background technology

The traditional power motor is to be its structural design basis with single-phase or 3: 2 patterns of three-phase mostly, with intentional formation non-equilibrium state, uses through uneven magnetic field and makes the rotor rotation, reaches power output; Yet, general motor is to be provided with the cylindrical rotor of permanent magnet, and ladle cover is in the outer rim of the stator yoke iron that is provided with magnetizing coil, and establishes rotating shaft in rotor center, this rotating shaft is arranged in the centre bore of stator again, uses to make rotor be able to rotate with respect to the stator concentric circles.

And by above-mentioned component composition, traditional as can be known power motor structure is in making that combination is gone up even during actual the use, will following shortcoming being arranged still:

Because stator is in turn-on power, be to adopt 3: 2 forms to arrange between electromagnetic field that it produced and the existing permanent-magnetic field of the permanent magnet of rotor, inhale mutually and the uneven reciprocation of repelling each other to produce, this is because of due to the deliberately uneven design of structure, it is the main factor that this uneven motor can be turned round smoothly, yet the uneven generation that consume is just arranged, loss as torsion, the energy etc., its characteristic of general motor is that greatly then rotating speed is low for torsion at present, rotating speed height then torsion is low, form the inverse ratio state, improve simultaneously, be difficult to reach for asking torsion and rotating speed.And most important general motor is not always broken away from the power loss that " stinging the tail phenomenon " caused.

Summary of the invention

The purpose of this invention is to provide a kind of full-balance power motor, the present invention make every effort to that torsion is big, rotating speed is high and consume few.Yet, consume at least and must ask balance, but as obtaining balance, just can't rotate, because of the existing phenomenon of physics ' flat then quiet, injustice is then moving ' as if should its power its balance again, then must in imbalance, ask for balance, again because of the external rotor arm of force greater than internal rotor, so can obtain bigger torsion.So the present invention adopts the external rotor mode to design.

The present invention adopts N, the S utmost point magnet that external rotor becomes even numbers, and the consecutive intervals of adopting at a distance of 120 degree potential differences is provided with pattern, what the collocation internal stator was provided with even numbers equally can be separately that magnetic poles such as N, S or O are corresponding, and to impose one be that main circuit structure is controlled by CPU, by this to form the unbalanced construction design in the balance, and the purpose of acquisition running, and further reach the high efficiency running of the absolute saving energy and the output of big torsion, and with volume production effect and advantage easily etc.

The present invention is described in detail with instantiation below in conjunction with accompanying drawing.

Embodiment

Referring to Fig. 1, the full-balance power motor that the present invention is designed, mainly be to be used in the external-rotor motor pattern, possess on the whole it construct the elementary cell that constitutes external-rotor motor is arranged, the design of structure such as internal stator 1 as shown in FIG. and external rotor 2 and circuit structure 3, because all non-pass of spare part this case creation emphasis of other collocation, so allow no longer being described herein, only just the feature of case of the present invention is introduced in detail more; Wherein:

This internal stator 1 is to possess to have a plurality of N group, S that are the even numbers kenel to organize magnetic pole 10 (in the present embodiment for being provided with six groups, every group of four magnetic poles are total to a 24 magnetic pole), this N group is to adopt synchronous replacement pattern with the magnetic pole 10 of S group, and each magnetic pole 10 all can be independently or is formed different magnetic poles such as the main pole kenel of N or S and O (sky) utmost point separately, with a plurality of magnet 20 of corresponding external rotor 2 respectively.

2 of this external rotors possess in magnet 20 present embodiments that have plural number to be the even numbers kenel equally adopts three N utmost point magnet (N1, N2, N3), three S utmost point magnet (S1, S2, S3), totally six magnet, then comprise in configuration as for it and respectively to adopt each at a distance of 120 consecutive intervals pattern settings of spending for the magnet 20 of the N utmost point and the S utmost point with a plurality of, and each magnet 20 (N1～N3, it is each one group of four magnetic pole 10 of containing above-mentioned 6 groups of magnetic poles 10 that S1～S3) forgives scope, these four magnetic poles 10 include two magnetic poles 10 that are different from these magnet 20 magnetic respectively, the magnetic pole 10 of a neutrality (sky) magnetic, and a magnetic pole 10 that is same as these magnet 20 magnetic is (as N, O, S, S or S, O, N, two kinds of patterns of N), and be mutual constantly alternate to each other, in order to do cooperating external rotor 2 magnet 20 to make pole change forever, to reach continuous running effectiveness.

About its circuit structure 3 parts, can cooperate referring to Fig. 2, calcspar shown in Figure 3 and circuit diagram, by the bridge circuit 32 that utilizes 31 utilizations of bridge switch 30 each single group coil of collocation (each magnetic pole) seen in the calcspar, be to change principle in order to the magnetic that shows above-mentioned every group of magnetic pole 10, and wherein locate the address detected that Hall IC 33 can provide the magnet 20 of external rotor 2, to make external rotor 2 when running Qi Shihuo stops, corresponding to set magnetic pole 10 positions of internal stator 1 just, above-mentioned again bridge switch 30, location Hall IC 33 grades link in addition a CPU (CPU) 34, and the multiply-connected direct current power supply that has, and can lead to by this and the running of CPU, obtaining polarity distributes, navigation system, control speed system, functions such as synchronization, and practical effects such as synchronous detecting and speed control.

According to above-mentioned power motor structure, in the application that reality is implemented, after importing direct current, motor can produce reaction and entry into service moment, please cooperate referring to Fig. 3 and running action schematic diagram shown in Figure 4; Now with regard to external rotor 2 in start of run, it is that example is done an explanation for the N1 magnet in the magnet 20 of the N utmost point:

This N1 magnet 20 has in four magnetic poles 10 the above two to be similarly under the attraction force acts of the magnetic pole 10 of S magnetic for least significant end in the magnetic pole 10 of S magnetic and last group of four magnetic pole 10 because of being subjected to itself containing, and the clockwise as seen in Figure 4 running situation of generation, arranging in pairs or groups simultaneously is positioned at least significant end in this group magnetic pole 10 and acts on for the repulsive force (being thrust) that the magnetic pole 10 of N magnetic is provided again, to impel its running; And in order to prevent because of adopting the poised state of even numbers magnetic pole 10 constitutes suction and thrust, and avoid producing so-called counter pull phenomenon (i.e. this group magnetic pole 10 latter two be subjected to the sucking action of the S3 magnet 20 at corresponding N1 magnet 20 adjacent rear itself for the magnetic pole 10 of N magnetic), the special group magnetic pole 10 of will putting in order is arranged in the magnetic pole state that the inefficient magnetic pole 10 in back side is designed to O magnetic (sky), and unlikely influence running, also be not enough to consume electric power, the so non-equilibrium state of institute's magnetic poles and the suction that can comprise the place ahead with acting as of producing of N1 magnet 20 and the thrust at rear, and non-equilibrium state reaches and continues running effect smoothly by this.

When N1 magnet 20 among the figure is come the position at original S1 magnet 20 places gradually, originally four magnetic poles 10 that are respectively S, O, N, N magnetic corresponding to S1 magnet 20 distributed control action because of the polarity that is subjected to CPU 34, early a step changes step by step becomes N, O, S, S magnetic pole kenel (and S3 magnet 20 should corresponding magnetic pole 10 when being moved to former N1 position gradually, also be changed to S, O, N, N magnetic pole kenel by original N, O, S, S), therefore can continue to make N1 magnet 20 to remain on suction, thrust and the combination of unresisted perfect running power.In like manner, by that analogy, all can be with the magnet 20 of the whole N utmost points that external rotor 2 is comprised and the S utmost point with the unbalanced power combination of this kind, and obtain the effect of high rotating speed, high efficiency and big torsion.

Be not difficult to find via above-mentioned explanation, the balance appeal point that case of the present invention is pursued is: three of being provided with 120 degree equi-angularly spaces in external rotor 2 inside be the N utmost point magnet 20, with three be the matched combined of the magnet 20 of the S utmost point, and six groups every group four magnetic poles 10 of having of internal stator 1 are total to a 24 magnetic pole 10 and design; Unbalanced demand part then be: in the combination of six groups every group of above-mentioned internal stator 1 each four magnetic poles, 10 common 24 magnetic pole 10, each magnetic pole 10 all can become independent N, S or O magnetic pole, and these change in polarity collocation kenels then are to control by CPU 34; Since each magnet 20 of external rotor 2 each magnetic pole 10 of running displacement apart from the time, four magnetic poles 10 of its pairing this group are made change in polarity already in advance, so can keep the perfect power combination of suction, no active force and thrust forever, therefore can reach stable high efficiency power output benefit, so be the unbalanced construction design in the perfect balance.

What deserves to be mentioned is, initial when external rotor 2 runnings, when magnet 20 is desired to leave several magnetic poles 10 of former correspondence, can produce the so-called tail phenomenon of inhaling, and impairment efficient; Therefore, the present invention utilizes the magnetic pole 10 that an O magnetic (sky) is arranged in the plural magnetic pole 10 of external rotor 2 each magnet 20 corresponding internal stator 1, pass in relative rotation is and is converted into the polarity of N or S magnetic pole (repulsion magnetic pole) by 0 (sky) magnetic pole 10, magnet 20 being pushed away the attraction of magnetic pole, and thoroughly overcome and inhale the tail phenomenon.

In sum, full-balance power motor of the present invention, the old uneven perfect structure that has in the balance of real as institute designs, and under the principle of not consuming power, can improve the essence effects such as rotating speed, torsion of motor.

Only the above only is a preferred embodiment of the present invention, can not be used for limiting practical range of the present invention; All equalizations of being done according to the present patent application scope change and modify, and all should belong in the scope that the present invention contains.
