I. Core Principia variabilis invitus soles

Primo, intelligere consilio, oportet intelligere suam fundamentalem differentias ex traditional vulnus-rotor solito:

· Traditional resolver, tum stator et rotor habetis. Excitatio signum et output signa electromagnetically adductus per aerem gap.

· Variabilis invita (VR) resolver, nisi in stator habet anxia . Et rotor est a non-vulnus feromagnetic pars facta de salientibus vectes vel dentatae structuram. Et opus principium fundatur in variation.

O stator et, typically includit unum excitationem curvis (primaria) et duos output Wallings (sine et cosinus, secundarium), quae sunt spatia orthogonal (XC electrica gradus seorsum).

O Rotor Rotatione, cum rotor cum salientibus vectes gyrari, mutat caeli gap longitudinem et invitus magneticam circuitu.

O signum modulation: et variatio in aere gap invitus modulat (amplitudine modulation) in voltage amplitudo adductus in output imbecilli per excitation magnetica agro. In amplitudine involucris duorum output imbecilli sunt sinusoidal et Cosinus munera rotor angulus, respective.

Et commoda sunt: ​​simplex structuram, aspera et durabile (Brushless), humilis sumptus, princeps reliability, facultatem ad altum-celeritate et summus temperatus environments . Incommodum est accuracy et linearity solent leviter inferior quam summus praecisione vulnus-rotor soles.

II. Design processus et clavis considerations

Design processum est iterative et typice sequitur hos gradus:

I. Define Design Specifications

Hoc est principium punctum pro omnibus consiliis et debet esse declarari prius:

· Numerus poli pairs (P): determinat necessitudinem inter electrica et mechanica angulos (θ_electric = p * θ_Manical). Commune configurationes sunt I polus par (unipolar) et II poli pairs (bipolar). Numerus poli pairs afficit accurate et maximam celeritate.

plerumque Recumpaciter Requisita ·: expressit in Arcminutes (') vel Milliradians (Mrad). Precisione excelsum requirit maxime princeps postulat in vestibulum materiae et magnetica agri harmonicos suppressionem.

· Input excitation signum: excitatio voltage amplitudine, frequency (communia sunt 4khz, 10khz, etc), waveform (plerumque sinuosoidal).

· Mutare Ratio (TR): Ratio de output intentione initus intentione (ad locum maximum coitus).

· Electrical errorem: Includes munus errorem, nullum voltage errore, tempus errorem, etc.

· Operating environment: Temperature range, vibrationis, inpulsa, humiditas, Ingress praesidium (IP) Rating.

· Size coactus; exterius diameter, interiore peperit, crassitudine (longitudinem).

· · : Imminedance PARAMETERS Input / Output Impedance, Affecting matching cum subsequent Circuitry.

II. Electromagnetic Design - Core Part

· Stator / Rotor Lamina Design:

O Material Electio: typically utitur Silicon ferro laminas cum princeps permeability et humilis ferrum damnum (eg, dwev440, 5JN400).

O polus-socors combination: Hoc est anima consilio. Numerus Stator Slots (ZS) et Rotor Saliens Polones (ZR) debet determinari. Communissima iunctura = 2p (numerum rotor vectes pares bis numerus poli) et ZS multiplex ZR. Exempli gratia, a Unipolar resolver (P = I), saepe utitur zs = IV, ZR = II ; A bipolar resolver (P = II) Saepe uses zs = VIII, zr = IV aut zs = XII, zr = VI.

Domine socors / poli figura, in figura dentium (parallela, attenuatis) afficit magnetica agro distribution et harmonicas contentus. Qualis dens latitudine, socors foramen latitudine, et iugum crassitudo opus optimization ad maximize fundamental magneto, motrici vis (MMF) et obscuratis socors.

O Aeris Gap: De Aeris Gap magnitudo est a critica commercia-off. A aeris gap auget transformationem ratio et signa vires sed auget vestibulum difficultatem, sensibilitatem ad eccentricitatem et torque lacum. A magna aeris gap habet oppositum effectum. Typically disposito inter 0.05mm - 0.25mm.

· : Cupidus Design

O Type: typically distribuit et intenta (dens) Wallings sunt usus. Distribuit (una coilning plures foramina) producendum magis sinusoidal agro sed magis universa ad fabricare; Concentrated imbecilles simpliciores sed altius harmonica.

O rursus calculation: fundatur in scopum transformationem Ratio, excitatio voltage, et frequency, determinare numerum vices ad excitationem curvis et sine / Cosinus per electro calculation. Numerus vicissim duas output imbecilliter esse stricte idem.

O Connection modum: ensure sinus et cosinus anterius in proprie XC electrica gradus seorsum divisionem.

III. Magna simulatio et optimization (Fea simulation) - Essential Mors Mors

Sere analytica calculations valde universa et satis accurate. Finite elementum Analysis (Fea) Software (eg, JMag, Ansys Maxwell, simcenter magnetem) est essential.

· Static Field simulation: calculate magnetica agro distribution, inductance matrix, et output potentia ad diversis rotor angulos.

· Transiens agri simulation: applicare in ipsa excitatio intentione ad simulare in output intentione waveform, magis verius reflectendo perficientur.

· Parametric Optimization: Exhibere Parametric Rudens et Optimization of Key Dimensiones sicut dens figura, aer gap, et socors ostium ad minimize errore (ut Ratio.

· Error Analysis: calculate electrica errore per simulation et analyze errorem fontes (eg, harmonica, cogging effectus, satietatem effectum).

IV. Mechanica structuram consilium

· Housing et Gestus: Design Support structuram et eligere oportet gestus ut concentus inter rotor et stator et minimam aeris gap variation, dum obstitit speciem et inpulsa.

· Shaft Connection: Design Keyways, lenis peperit, aut servo interface ad curare reliable nexu et backlash libero traductionem cum motor hastile.

· De scelerisque administratione, considerans calorem ex anfractus et ferrum damna ne overheating in altum temperatus environments. Scelerisque iter consilio interdum necessarium.

· Electromagnetic protegens: Add a clypeus, si necessarium ne intercessiones externa magnetica agris.

V. Signum processui Circuit Consid

Licet non parte resolver corpus consilio, considerandum synergistically:

· RDC (Resolver-ut-Digital Converter): Select an RDC Chip (eg, ad2s1205, au6802), quae aequet resolver scriptor impeditance et excitatio frequency. Input impedientia matching est requiritur in consilio.

· Excitital Coegi Circuit: requirit a potentia op-amp circuitu capax providente mundus firmum sine fluctus.

· Filter Circuit: filter in output annuit ad supprimere summus frequency sonitus et harmonica.

III. Design challenges et key technologies

1. Harmonic Suppressio: Ob ad non-linearity eius invitus variation, in output intentione a VR resolver continet dives harmica, quae sunt principalis causa erroris. Modi sicut polus-socors combination optimization, skewing (foramina vel vectes), et addendo auxilia foramina in stator dentes potest efficaciter supprimere harmica.

2. Balancing accurate et sumptus: High accurate importat magis precise machining (minor aer gap, altius concentus), altius qualis materiae (altius gradus Silicon ferro), magis complexu (eg, magis pender, ducens ad acriter augendae costs.

3. Temperature PERFLUO: et resistentia de Wallings et proprietatibus Silicon ferro mutatio cum temperatus, causando amplitudine et tempus egisse. Compensatio in circuitu vel software est opus, aut materiae cum bono temperatus stabilitas debet delectis in electro consilio.

Summary

Design suasiones:

1. Satus cum cubits: primo, penitus intellegere specifica requisita vestri application sem de accurate, magnitudine et environment.

2. Leverage Probatur Solutions: Satus cum Ordo polus-socors junctiones (eg, 4-2, 8-4), ut sint verificatur et fideles incipiens punctum.

3. Simulatio-repulsa consilium nolite ad speculatos calculations; Mox utor FEM Software creare paremetricus exemplar ad simulation et ipsum. Hoc est clavis ad improving consilium victoria rates et brevior progressionem cycles.

4. Iterate et test: post aedificationem prototypum, mores comprehensive perficientur probat (errore, temperatus ortum, vibrationis, etc.), comparare cum simulatio results, analhe causas differentiae et procedat ad proximum consilio.

5. Cogita ratio gradu considerate et Debug resolver sensorem et downstream RDC circuitu quod integrated ratio.

Consilio variabilis invitus soles est altus practica technology quod requirit saepe cyclis doctrina, simulatio et experimentationes.
