Embodiment

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

As shown in Figure 2 a, the N/S pole ring of at least 4 rotor units rotates body homopolarity to setting to the motor body foundation structure of electric device described in the utility model, different from the scheme that routine techniques N/S magnetic pole is alternately arranged.Stator unit 3a is by good wire wounded core, described good wire uses copper material or copper-plated metal usually, described magnetic core uses conventional magnetic media material, such magnetizing mediums be known to the skilled person a kind of under magnetic fields internal state change and the material of stronger complementary field can be produced.

See Fig. 2 b, 6 outer rims of turning arrange a rotor unit 3b, S pole-face is in turning, determine body 5 and a stator unit 3a is set near the position of turning, relative air gap 3d is enough little in both motions, if stator unit energising N pole-face to turning, then rotor unit convergence energising stator unit time, its electromagnetic attracting force can be subject to and make to turn accelerated motion; In another embodiment, the S polar motion stator unit in opposite directions of rotor unit, 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 c; It is the basic model of the utility model electric device that this stator unit electromagnetic pole and the attracting relation of rotor unit are arranged.

Rotor unit around axle stressed relevant in the interval of turning to stator unit electromagnetic field effect, be column or I-shaped stator unit to one around core, 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 the 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.

Rotor unit is on turning when axle moves, and electromagnetic force F suffered by it can be analyzed to coaxial normal 10 direction F ₁₀with around axle tangent line 11 direction F ₁₁, wherein opposing connection axle is contributive is F ₁₁; Meanwhile, rotor unit and the determined normal of axle and stator unit and the determined normal of axle define a dynamic angle it is a special state, now angle that its tangential direction around axle convergence stator unit overlaps with suffered electromagnetic force F action direction for definite value as shown in fig. 4 a; The useful effect of electromagnetic force suffered by rotor unit is interval, be positioned at to be 0 state be benchmark in lane place (described ± relatively to define according to the direction of rotation of turning).When when being 0, F ₁₀for maximum, F ₁₁be 0, now 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 for separation, status and appearance be with tangential actuating force F ₁₁be main, status and appearance be with normal direction braking force F ₁₀be main.

The Driving technique scheme of the utility model electric device is: power supply modulator is corresponding state time domain energising, all the other time domain power-off; When design object is for economize on electricity, preferably even corresponding time domain energising; When needing to make full use of the moment of inertia of turning, preferably even corresponding time domain energising; Cause state with braking force F ₁₀be main, state energising has lost optimization meaning to driving; The break-make time domain of this drive current described 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 energising, described T ₂for rotor unit is corresponding around axle time domain, described T ₀for rotor unit is away from the time domain of stator unit, in like manner, because of ? there is considerable tangential force F in state ₁₁, unhelpful to braking.

Above-mentioned basis the switching electric control of state, can approximate transform be that relative time controls, know because power supply modulator is easily sentenced by timing alignment from arrive be 0, i.e. (T ₁+ T ₂) time period, as long as setting T ₁with T ₂relative time, it is right to be namely equivalent to the switching electricity temporal scalable of corresponding state; Such as control corresponding extremely time domain energising, can briefly be set as at (T ₁+ T ₂) time period initial 1/2 time domain energising, 1/2 time domain power-off afterwards; In like manner, control is worked as corresponding to the time domain energising of 0, can briefly be set as at (T ₁+ T ₂) time period initial 2/3 time domain power-off, afterwards 1/3 time domain energising; (T ₁+ T ₂) be an amount relevant to rotating speed of turning, determine with the relative time of timing cycles state there will be deviation when speed change state, this relative time-offsets is corresponding by power supply modulator be 0 state calibrate, correct in next cycle.

be the magnetic action hidden variable of an association stator unit and the rotor unit plan of establishment, normally use be 0 and for aobvious state position judge the one foundation of the inner relative position of electric device as sensing device; 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, should through test inhabitant area during specific design.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.

Moment and the set electric current sequential of power supply modulator startup power supply directly define direction of rotation of turning, when the corresponding described rotor unit of sequential electric current is positioned at for extremely for state area between arrange (herein-value interval with be 0, relatively aforementioned power supply time domain respective rotor unit is positioned at setting area between and relatively define), then corresponding clockwise direction of turning rotates, Fig. 7 d denote a kind of structure and Fig. 7 b roughly the same, and the corresponding T of dextrorotation veer of turning ₁, T ₂and T ₀the signal region of sequential.

As shown in Figure 8 a, determine body and arrange two stator unit 3a, arrange 8 rotor unit 3b on turning, turning in swing circle, power supply modulator will provide 8 cycles for (T for two stator units respectively ₁+ T ₂+ T ₀) sequential electric current; Further 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 the combination of H stator unit and n rotor unit, if power supply modulator is to H the discrete power supply of stator unit winding, need corresponding design 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 3a, 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 the signal source that a kind of rotor unit and stator unit relative position differentiate, 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 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 is around axle 7 cycle movement, the rate of change that sensing unit can obtain electric current (voltage) feeds back to power supply modulator, and power supply modulator is sentenced according to this induced signal the relative position of knowing rotor unit 3b and correspondingly sent electric current sequential.According to the operating accuracy of sensing unit 3c 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 induced signal input 1c of power supply modulator is corresponding built-in.

In sum, described power supply modulator is a logic power switching system, sequential power cycles/frequency reflects unit interval internal stator unit 3a to the effect 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.

The traditional product of driving actuation means 9a is rheostat or the potentiometer of a deformation design, generally be designed to conventional rotating handles formula, in recent years be much based upon special actuation means that is photosensitive, Hall control technology basis to reach its maturity, also can be designed to the control mode of plug-type joystick or some constant speed gears, comprise remote control.

When electric device needs to set 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.

The utility model electric device has a kind of special state when starting, when rotor unit be just in be in stator unit trapping gap same normal 10, when being 0, easily there is stall.As non-cooperation electric motor car is designed to power-assist starting, can to the static start-up routine of power supply modulator respective design electric device; A simple example of the static start-up routine of described electric device, that power supply modulator is when setting-up time maximum can not get sensing device feedback signal, send the starting current contrary with normal drive current direction in real time, above at least one rotor unit that makes to turn is subject to same polarity and repels each other and depart from be the state of 0, avoid electric device to start not smoothly.

Stator unit interior arranges main points turning, the relative air gap 3d that will make rotor unit that magnetic action effectively occurs with its formation in Periodic Rotating, this air gap is that stator unit transmits the energy channel of electromagnetic force to rotor unit, air gap is more little is more conducive to magnetic energy effect transmission, but the too small easy generation Mechanical Contact of air gap, needs comprehensive rigidity and the machining accuracy of holding material during design.

When the optimum speed/torque of electric device needs add-on device to adjust, can install additional by the deceleration/torque changing apparatus 2 of some gear combination in 6 outsides of turning, deceleration/torque changing apparatus can reach the rotating speed changing machine driving input or the technical goal changing torque by the combination of some gears, the design of deceleration/torque changing apparatus is more, is preferably coaxially arranged at outside of turning with turning; Deceleration/torque changing apparatus both can independently be arranged, also can in outside implementation integral design of turning; Even be deformed into and design with outer buttons rotary device disjunctor; But when outside non-coaxial of turning arranges deceleration/torque changing apparatus, the adjustment such as suspension, damping spring center of gravity usually need be configured, not preferred scheme.
