Preferably two kinds different substrate materials combinations are arranged；Preferably two kinds substrate combination arrange and are because permanent magnet and magnetic conductor has master
Dynamic load magnetic and by two kinds of different qualities of dynamic load magnetic, can combine according to its different qualities variation, drives adapting to washing machine
Move, brake the technology of multiple real-time status and control requirement.
Electromagnetic force F suffered by above-mentioned rotor unit can be analyzed to coaxial normal 7 direction F10With tangent line 8 direction F11, wherein
Contributive around axle 6 to rotor unit is tangential forces F11, F and F10Direction define dynamic angle theta.Turn
Electromagnetic force suffered by subelement is relevant to the electromagnetic action interval of stator unit, single column or the I-shaped stator around core
The unit electromagnetism line of force passes through the maximum of air gap, corresponding to electromagnetic pole the two poles of the earth line 9 with it at the normal residing for turning barrel
7 is vertical, as shown in Figure 3 a；Column or the I-shaped stator unit around core also may be configured as electromagnetic pole the two poles of the earth line 9
Overlapping at the normal 7 residing for turning barrel with it, as shown in Figure 3 b, this set-up mode is usually the combination of multiple stator unit
Select during arrangement；For matrix around the stator unit of core, its electromagnetic force is interval to the useful effect of rotor unit, is positioned at
Matrix is in the range of core both upper ends thereof is just to the two ends of turning barrel 5 inner edge, as shown in Figure 3 c.
When axle convergence stator unit, there is F and F in rotor unit11The state overlapped, this special state shows
Overlap around axle tangent line 8 direction with rotor unit for F, with effective stress of electromagnetic force state description rotor unit
Interval, corresponding to rotor unit be in stator unit coaxial normal 7 trapping gap relative on the basis of (θ is 0 state),
θ is (described ± to define according to the direction of rotation of turning barrel) in the interval, position of ± 90 degree；When θ is 0, F10
For maximum, F11Be 0, this state to rotor unit around axle without contribution, as shown in Figure 4 b；F11And F10Be a pair this
Disappear those long kinematic variableses, its theoretical strong and weak conversion with θ be 45 degree as separation, at the state table of θ ＞ 45 degree
It is now with around axle driving force F11Being main, the status and appearance θ ＜ 45 degree is with brake force F10It is main.
The actuation techniques scheme of the electric device of washing machine of the present invention is: corresponding 30 degree≤θ≤90 degree of power supply modulator
Time domain energising, remaining time domain power-off；In this energising time domain, should select at 60 degree≤θ based on the design of economize on electricity
The time domain energising of≤90 degree of even 75 degree≤θ≤90 degree；Need to make full use of the design of turning barrel rotary inertia, can
Select the time domain energising of even 30 degree≤θ≤90 degree 45 degree≤θ≤90 degree；Owing to θ is in 45 degree of states of ＜
With considerable F10, lost economize on electricity in 30 degree of state energisings of θ ＜ and optimized design sense；This electricity preferably driven
The disconnected time domain of circulation as shown in Figure 6 a, wherein T1For conduction time, T2And T0It is power-off time, (T1+T2+T0) structure
Become Timing driver current cycle T.The braking technology scheme of the electric device of washing machine of the present invention is: power supply modulator
Corresponding T2And T0Part time domain or all time domain be set to energising, described T2For rotor unit around axle convergence stator list
The time domain of corresponding 0 degree≤θ≤30 degree of unit, described T0For rotor unit around axle away from the corresponding time domain of stator unit；
In like manner, there is considerable tangential electromagnetic force F due to 30 degree of states of θ ＞11, unhelpful to Brake Design.
The corresponding control according to ∠ θ state to switching electricity of above-mentioned power supply modulator, can approximate transform be relative time
Control, because power supply modulator can be sentenced known that θ is from 90 degree to 0 degree, i.e. (T by timing alignment1+T2) time period,
As long as setting T1With T2Relative time, be i.e. similar to the switching electric control to θ corresponding state；Such as control θ
The time domain energising of corresponding 90 degree to 45 degree, can briefly be set in (T1+T2) time period initiate 1/2 time domain energising,
1/2 time domain power-off afterwards；In like manner, when the time domain controlling corresponding 30 degree to 0 degree of θ is energized, can briefly be set in
(T1+T2) time period initiate 2/3 time domain power-off, 1/3 time domain energising afterwards；(T1+T2) time period be one with
The amount that turning barrel rotating speed is relevant, to determine that the state that θ is 90 degree judges to there will be partially cycle time when turning barrel speed change
Difference, owing to power supply modulator correspondence θ is that 0 degree of state is provided with time calibration, need to correct in next cycle in time.
∠ θ is an association stator unit and the magnetic interaction hidden variable of the turning barrel rotor unit plan of establishment, works as machine
After stator unit setting on frame (including that combination is arranged) scheme determines, the while that corresponding θ being the aobvious state position of 90 degree
It is determined；Be typically use θ be 90 degree and θ be 0 aobvious state position judge electric device as sensing device
The one foundation of internal position relatively, and power supply modulator is sent accordingly work order；θ is the accurate position of 90 degree
Put be one to turning barrel radian, air-gap separation, stator unit around the relevant value of the parameters such as core shape and arrangement thereof, have many
Plant theoretical model, should be through test inhabitant area during specific design.Power supply modulator exports driving or the work of stalling current accordingly
Logic, both can be controlled circuit by ordinary tap and realize, it is possible to use CPU programming to combine power model group circuit realiration,
Or the special chip using large scale integrated circuit technology to manufacture realizes.
The work-based logic transformation directive signal of power supply modulator is typically to obtain from the sensing unit 3c being connected in frame,
As Fig. 5 a shows, common sensing unit is magnetoelectric induction winding, Hall element or photoelectric encoder etc., works as rotor
Unit is when axial period moves, and sensing unit can obtain the rate of change of electric current (voltage) and feed back to power supply modulator,
Power supply modulator is sentenced according to this induced signal and is known that the relative position of rotor unit sends sequential electric current accordingly.According to biography
The operating accuracy of sense unit and reliability requirement, can arrange one or several sensing units in frame, even deform
For the mode fed back from said stator unit Multiple coil and the winding feedback using stator unit two-wire wounded core
Mode obtains work-based logic transformation directive signal (as Fig. 5 c shows), now the induced signal input of power supply modulator
Holding the most built-in, its response processes the working procedure logic to power supply modulator and proposes high requirement.
T1Time domain is attended by the F showing as brake force10, have one and drive and braking, useful work and power consumption/heat radiation
Optimal selection problem, due to F10Driving electric device is potential accumulated heat source, and cannot in Timing driver electric current
By F10It is completely separated, a kind of weakening F10The preferred version affecting potential accumulated heat is: at T1By strong for energising in time domain
