Embodiment

Further the utility model is described in detail below in conjunction with drawings and Examples.

A kind of motor body foundation structure of electric device described in the utility model as shown in Figure 1a, arrange in the same way, different from the scheme that routine techniques N/S magnetic pole is alternately arranged by the N/S magnetic pole of 6 upper rotor part unit of turning; Described turning can be the wheel rim of wheel 5, as shown in Figure 1 b; Or described wheel hub, as illustrated in figure 1 c; Also can be the annular machinery circle be coaxially arranged in wheel, as shown in Figure 1 d.Stator unit 3a is formed by good wire wounded core, described good wire uses copper material or copper-plated metal usually, magnetic core uses conventional magnetic media material, can produce the material of stronger complementary field under a kind of outside magnetic field effect that such magnetizing mediums is known to the skilled person.

See Fig. 2 a, turn on 6 and a permanent magnet rotor unit 3b1 is set, its S pole-face is to the axle 7 of turning interior, a stator unit 3a is arranged on the fixed position of close rotating inner edge, the N pole-face of its winding energising is to turning, relative air gap 3d is enough little in both motions, then, during the stator unit of rotor unit convergence energising, can be subject to stator unit magnetic action and attract and make to turn accelerated motion; In another embodiment, the S polar motion stator unit in opposite directions of permanent magnet rotor unit 3b1, body direction of rotation is reversed corresponding thereto in the N pole of stator unit winding energising, and both magnetic action are similarly attracting, as shown in Figure 2 b; If turned, that upper setting is magnetic conductor rotor unit 3b2, and because its year magnetic is for by stator unit electromagnetic field inducing institute extremely, no matter how the energising direction of stator unit winding is arranged, and both magnetic action are attracting, as shown in Figure 2 c; It is the basic model of electric device described in the utility model that this stator unit electromagnetic pole and the attracting relation of rotor unit are arranged, preferably two kinds of different substrate materials combinations are arranged, initiatively carry magnetic because permanent magnet and magnetic conductor have and by two kinds of different qualities of dynamic load magnetic, can combine according to its different qualities variation.

As shown in fig. 4 a, during the stator unit that rotor unit is energized around axle convergence, suffered electromagnetic force F can be analyzed to normal 10 direction F ₁₀with tangent line 11 direction F ₁₁, wherein contributive around axle to rotor unit is F ₁₁, F and F ₁₀direction define dynamic angle theta.Rotor unit is stressed relevant in the interval of turning to stator unit electromagnetic field effect, opposing connection core is column or I-shaped stator unit, its electromagnetism line of force passes through the maximum interval of air gap, corresponding to the state of electromagnetic pole the two poles of the earth line 12 vertical to the corresponding normal 10 of turning (parallel with corresponding tangent line 11), as shown in Figure 3 a; Column or I-shaped the two poles of the earth line that also can be set to electromagnetic pole around core overlap to corresponding normal of turning, and as shown in Figure 3 b, select when this set-up mode is generally multiple stator unit combination arrangement.For matrix around core, its electromagnetic force, between the active region of rotor unit, is positioned at matrix around core top just to the two ends scope of turning, as shown in Figure 3 c.

Enter the interval of stator unit electromagnetic field effect at rotor unit around axle, there are two electromagnetic force state particular points, one is F and F ₁₁overlap, show as F to overlap around axle tangential direction with rotor unit, with between effective force area of electromagnetic force state description rotor unit, be positioned at rotor unit and stator unit and be between coaxial normal 10 (θ is 0 state) is benchmark, θ is ± 90 degree lane place (described ± to define according to the direction of rotation of turning); When θ is 90, F ₁₁for maximum.Another electromagnetic force state particular point is F and F ₁₀overlap, θ is 0, F ₁₁be 0, F ₁₀for maximum, now electromagnetic force to rotor unit around axle without contribution, as shown in Figure 4 b; F ₁₁and F ₁₀be a pair shifting kinematic variables, its theoretical strong and weak conversion with ∠ θ be 45 degree for separation, be with around axle actuating force F at the status and appearance of θ > 45 degree ₁₁being main, is with normal direction braking force F at the status and appearance of θ < 45 degree ₁₀be main.

The Driving technique scheme of the utility model electric device is: the time domain of corresponding 30 degree of power supply modulator≤θ≤90 degree is powered, all the other time domain power-off; In this time domain, power based on the time domain that the design of economizing on electricity should to be selected in 60 degree≤θ≤90 degree or 75 degree≤θ≤90 degree, the time domain that moment of inertia of turning can to select in 45 degree≤θ≤90 degree or 30 degree≤θ≤90 degree need be made full use of and power; Because θ < 30 degree of states are with F ₁₀be main, its power supply is without driving meaning; The break-make time domain of this drive current as shown in Figure 6, wherein T ₁for conduction time, T ₂and T ₀be power-off time, (T ₁+ T ₂+ T ₀) constitute Timing driver current cycle T.The braking technology scheme of the utility model electric device is: the corresponding T of power supply modulator ₂and T ₀part time domain or all time domain be set to power supply, described T ₂for the time domain of rotor unit around corresponding 0 degree of axle convergence stator unit≤θ≤30 degree, described T ₀for rotor unit is around the corresponding time domain of axle away from stator unit; In like manner, θ > 30 degree of states are with considerable tangential electromagnetic force F ₁₁, unhelpful to electric device braking.

Above-mentioned power supply modulator, according to the control of the dynamic corresponding switching electricity of ∠ θ, can approximate transform be that relative time controls, because power supply modulator is easily sentenced by timing alignment know that θ is from 90 degree to 0 degree, i.e. (T ₁+ T ₂) time period, as long as setting T ₁with T ₂relative time, be namely equivalent to the switching electric control to θ corresponding state; The time domain energising of such as corresponding 90 degree to 45 degree of control θ, can briefly be set in (T ₁+ T ₂) time period initial 1/2 time domain energising, 1/2 time domain power-off afterwards; In like manner, when the time domain energising of corresponding 30 degree to 0 degree of control θ, (T can be briefly set in ₁+ T ₂) time period initial 2/3 time domain power-off, afterwards 1/3 time domain energising; (T ₁+ T ₂) time period is an amount relevant to rotating speed of turning, to judge that the real-time status of θ has deviation in speed change state cycle time, this deviation depends on power supply modulator to be that 0 degree of state carries out correcting in time in next cycle time calibration at θ.

θ is the magnetic interaction hidden variable of a rotor unit and stator unit relative motion, after internal stator unit setting (comprising combination) scheme of turning is determined, corresponding θ is that the aobvious state position of 90 degree is determined simultaneously, its exact position be one with radian of turning, air-gap separation, stator unit around the value of the parameter correlations such as core shape and arrangement thereof, have multiple theoretical model, specific design should through test inhabitant area.The corresponding work-based logic exporting driving or stalling current of power supply modulator can be realized by ordinary tap control circuit, and CPU also can be adopted to programme in conjunction with power model group circuit realiration, or the special chip adopting large scale integrated circuit technology to manufacture realizes.

Fig. 7 a is the partial structurtes schematic diagram that a stator unit combines 8 rotor units, stator unit turn a swing circle π respectively with 8 rotor unit generation magnetic action, the theoretical sequential electric current that power supply modulator is corresponding is divided into 8 (T ₁+ T ₂+ T ₀) cycle, it is π/8, the T corresponding with rotor counterclockwise direction of rotation that Fig. 7 b denotes a kind of T of setting ₁, T ₂and T ₀schematic frequency domain, Fig. 7 c is the energising logical schematic of one of them cycle T.Rotor unit not arranges The more the better, and its number n on turning is limited to the interval corresponding space occupy-place of suffered stator unit electromagnetic force useful effect, otherwise the sequential current cycle that power supply modulator correspondence exports can be overlapping.

As shown in Figure 8 a, turning interiorly arranges two stator units, arranges 8 rotor units, turning in swing circle on turning, and power supply modulator will provide 8 cycles for (T for two stator units respectively ₁+ T ₂+ T ₀) sequential electric current, this kind of combination set-up mode is generally applicable to the wheel rim of wheel; Rotor unit is arranged on to the design of wheel hub inner rotary member, can preferably 8 stator units combine 10 rotor units, 12 stator units combine 12 rotor units (as shown in Figure 8 b), etc.In theory when H stator unit and n rotor unit Combination Design, if power supply modulator is to H the discrete power supply of stator unit winding, need corresponding design n*H electric current sequential, i.e. n*H (T ₁+ T ₂+ T ₀) electric current sequential, programming will be very complicated; Therefore in the utility system design of multiple stator unit, preferred H stator unit winding electric tandem compound, or H stator unit winding is divided into some groups of external power supply modulators; The such as windings in series of 12 stator units, tap totally three external electric connection of power supply modulators of line are drawn in the middle of every 4 windings, the difference of the differetial-potential that technically these three lines also can be utilized to compare between two, as a kind of signal source differentiating rotor unit and stator unit relative position, substitute the independent sensing unit arranged.

Power supply modulator can realize by ordinary tap circuit design or pulse digit technology, the fundamental functional modules of the latter generally comprises power converting circuit, the microprocessor of internal memory contain working procedure and signal input and output circuit, correspondingly controls by sensing unit 3c feedback signal the sequential electric current that driver module exports; Groundwork logic such as Fig. 5 a of power supply modulator shows, and Fig. 5 b is a kind of block combiner schematic diagram realizing digital technology logic.

The work-based logic transformation directive signal of power supply modulator normally obtains from the sensing unit 3c being connected in turn inside or outside, sensing unit is not limited to use magnetoelectric induction winding or Hall element, also photoelectric encoder etc. can be used, when rotor unit moves around axial period, the rate of change that sensing unit can obtain electric current (voltage) feeds back to power supply modulator, and power supply modulator sends electric current sequential according to its transducing signal is corresponding.According to the operating accuracy of sensing unit and reliability requirement, sensing unit can turn inside or outer setting one or several, even be deformed into become the mode of multi-thread circuit feedback from above-mentioned multiple stator unit windings in series and use stator unit 3a Double-wire ring around winding feedback mode obtain work-based logic transformation directive signal, now the transducing signal input 1c of power supply modulator is corresponding built-in, and its response process proposes high requirement to the working procedure logic of power supply modulator.

To sum up, described power supply modulator is a logic power switching system, sequential power cycles/frequency reflects unit interval internal stator unit 3a to the energization action number of times of rotor unit 3b, the rotating speed that this time sequence frequency remote definition is turned and the energising amplitude needed for stator unit or electromagnetic force (coming from power supply modulator to be energized to the winding of stator unit), energising amplitude is larger, unit interval internal stator unit energising is larger to the active force of rotor unit, effect number of times is more, and the rotating speed of consequently turning is faster.The time sequence frequency of power supply modulator institute output current, rotates the implicit (T of one-period with turning ₁+ T ₂+ T ₀) sequential effect number of times, energising mean intensity and the rotating speed of turning be mutually corresponding all physical quantity relations, after power supply modulator many imposes a condition and enter logic working state, the frequency controlling sequential energising namely controls the rotating speed of electric device.The rotating speed of this Artificial Control electric device is by driving the input 1d of actuation means 9a electric connection of power supply modulator to realize.

Described driving actuation means 9a is set to the mode that foot chain wheel controls electric device rotating speed, is to be based upon power supply modulator to be inversely proportional to foot chain wheel swing circle to the output current/time sequence frequency of stator unit winding or to say on the method basis that is directly proportional to foot chain wheel speed.This technical goal can adopt conventional art to realize, and such as in foot chain wheel rotates, region corresponding to cycle arranges a magnetoelectric induction device, by the electric impulse signal periodically obtained, power supply modulator is sentenced to know the speed of a motor vehicle required for bicyclist; The technology such as the electric motor car parts employing that this technical goal also can be correlated with at foot chain wheel and swing circle thereof is photosensitive, Hall control realize.Namely described power supply modulator stepping constant current strength fixes the control mode of electric device rotating speed, can be designed to some gears, and such as 1 grade controls electric device rotating speed for switching to ride, certain setting speed of a motor vehicle of 2 grades, 3 grades, the 4 grades corresponding electric motor cars of difference.

When electric device sets up electromagnetic force braking function, the corresponding brake signal input 1e set up of power supply modulator is electrically connected with electro-magnetic braking device 9b, as shown in Figure 5 c; The braking energising intensity that the function of electro-magnetic braking device exports for controllable power modulator, braking electrical current is larger, and electromagnetic braking effect is better.
