Usus LM331 et PMM8713 et si -73004 planning quattuor tempus stepper motor coegi circuitu, coegi circuitu habet secure officium, et torque-celeritate proprium in altum efficientiam et bonos, et applicantur ad numerum actively imperium et arcus pressura superioris. Motor est quaedam electrica pulsus in angulari obsessio actuorum potest per manipulation pulsus numerum control angulari displacement quantitas et ad intentionem accurate positus; Togruction ad volumen per manipulation pulsus frequency ad imperium motor celeritate et accelerationem et ad celeritatem intentionem. At present, the control of step motor are mainly composed of dispersion equipment annular pulse distributor, software annular pulse distributor, special integrated chip annular pulse distributor, etc. This plan, choose the third PMM8713 three-phase or four phase pulse distributor of stepper motor, SI -7300 a two phase or four phase power drive, a four phase stepper motor drive circuit, power integration and strong sex to progressus. Hardware Profile PMM8713 est Japan scriptor Sanyo Electric Company facit Pulse Distributor de stepper motor, idoneam ad manipulation trium-phase quattuor tempus stepper motricium. Manipulation trium, tempus vel quattuor tempus stepper motor potest eligere III species excitation modum, per tempus minimum suctu ad trahendum ad XX MA current, non solum satisfactum initus inputs of SCHMITT trigger, et embedded inputs of SCHMITT Tigger Circuit, Fortis Anti-Jamming Capitability. In internum Circuitum PMM8713, quidam est ad Clock Gating de Stepper motricium est Gyratorius Pulsus input. Sunt duo genera PMM8713 pulsum input modum: duplex pulsum initus modum et unum pulsus input modum. Cum eligens duplex pulsus input modum, CP, CU Duo initus separationem gradus motricium sunt convertens potestate pulsus. Electus per unum pulsum input, stepper motor est rotundo directionem per u / D excelsum resolutio, humilis potentiale. Ratio modum eligere eligere quod genus excitation imperium circuitu. Exhortare modum iudicandi circuitu output deprehensio; Et reversible anulum contra est ad producendum gradum motricium in lectus excitationem modum sub eadem leo signals. Si-(VII) CCC a layout et potentia coegi principle de Si -7300 est Iaponia scriptor tres viridi comitatu planto summus munus in stepper motricium integrated Power Amplifier, in apparatu ad unum polarity quattuor Phase coegi, eligere Sipi8 Encapsulation. Power Coegi Circuit in duplicis dividitur in duas voltage et vena repulsi accessus. Current repulsi accessus est maxime solebat PWM constant current chopper coegi circuitu, quod est maxime communiter usus modi ex princeps munus exactoris. LM331 chip lm331 est nationalis semiconductor turba facit dual-in-linea VIII pedites chip, tantum opus ad accedere paucis externa components potest facile constituunt a voltage / frequency (v / f) switch circuitu. LM331 output frequency et input intentione contactus quod erant ut sequitur: F = VI / (irtirl) T sub>,;;; I punctualis per externum components rt et ct resolutio, T1 = I. I RTCT, ir a internum praecisione current fons copia, ir = I. RS ad adjust lm331, et ad adjust lm331. Partes est ad adjust lm331. Partes = Rs. Rs est ad adjust LM331. CT pro filter capacitance, solet 0. I ~ 0. UF, I casu est in melius filtering effectus, potest uti I u f capacitance. Ut progredi gradum accurate et stabilitatem, coetus elementum eligere apparatu humilis temperatus coefficientem. Usus pro usu PMM8713 Motor Ring Distributor et S17300a Stepper motor Power AMPLIFICIBUS planning quattuor phase stepper motor potentia coegi Circuit, PMM8713 adopt unum pulsum initus, I -two Modus ager. PD potestate finis ad S17300a initus current IO control finem, potest suspenderunt aut altus campester, post excelsum gradus potest esse convenienter S17300a output current IO, dangling in usum ratio application. Per LM33L PMM8713 Clock Pulse input Signum (V / F) output, in directionem et step motor satus-subsisto imperium signum comparationis circa datur per fenestram. Fenestra Circuit enim gradus Motor Supple directionem imperium signum et gradum motricium satus-subsisto imperium signum. Interim U1 U2 ad CNC Plasma Cutting Machina, Arcus pressura, inferioribus voltage ui ad deprehendere arcus pressura. Cum Ui> U1, V3 output ad excelsum gradu, in V4 output ad humilis campester, V5 output ad altum gradum; V3 et V4 cum U2 <ui directionem imperium signo output terminum PMM8713 C / D, Manipulation Motor motricium est rotating; R U5 Output Termination PMM8713 reset finem, satus-subsisto imperium procedens motricium. LMM331 (V / F) output FO PMM8713 CK, ad suppleret step motor cum pulsum imperium signum. Ut, cum U2 <ui <U1, V5 output ad humilis campester, gradus motor motus; When the Ui > U1 perhaps Ui < U2, V5 output for the high level, step motor sports (Stepper motor is rotating direction control signal manipulations)To U2 < Ui < U1 range, then make sure that the Ui is always located U2 < Ui < Ul range. In driving circuitu est in numerali control plasma arcus secans apparatus pressura inceptum suscitare system, quod ratio motricium est XLII BYG009 Type est in parvis electromechanical integration est in integralis in integral, potest in parvis electromechanical integration apparatu.
