Dc servo motor servo motor in nc feed servo system was widely used, it has good speed and torque characteristics, but its complex structure, high manufacturing costs, big volume, and motor brush is easy to wear and tear, commutator produce sparks, the capacity of the dc servo motor and using occasions restricted. AC servo motricium sine penicillo et commutator et alia structural defectus; Et novum genus potentiae switch fabrica, applicationem-specifica integrated circuitu, progressionem computatrum technology et imperium algorithm et sic in, ut promoveantur ratio AC AC coegi potest aptet ad Ratio NC Machina. Modern NC Machina Tools tendunt ad agi a ac servo, ac servo coegi reponere DC servo coegi. I. De structura AC AC Motor ac motricium cum actum motricium motricium et AC Synchronum motricium. AC Induction motricium habet simplex structuram, magna capacitatem, humilis prices, plerumque uti background motus in coegi motricium. Permanens Magnet Synchronous ac Servo motricium adhibetur ut coegi motor feed motus et structuram schematic ostenditur in Figura I. motricium est de stator et rotor et detectum elementum. Et stator per involutum laminam, ejus specie est polygoni, nullum basis, ita ut ad calorem deflectitur. Embedded in stator dens logarithmi trium, tempus curvis. Rotor per involutum laminam, et in quibus instructum est permanens magnes, logarithmica et stans polus logarithmica idem. Permanens magnes sunt: Alnico, Ferrite et Rare Terra permanens Magnet NDFEB Alloy, Alloy cum Rare terra permanens Magnet Alloy perficientur est optimus. Detecting elementum cum pulsus encoder, etiam potest uti transformer Tachogenerator, solebat deprehendere anguli positus, displacement et rotating celeritate motricium, ut providere absoluta situ permanens notitia, feedback et in loco, ut feedback feedback, feedback moles. 2. Ac servo motor frequency control of ac motor speed n, very logarithmic p with ac power frequency f, the motor and the relationship between the transfer speed skating rate s (1)For asynchronous motor s≠ S = 0, 0, for synchronous motor. Per genus (I), mutare potentia frequency F, motor celeritas mutat ut recta proportio n et f. Motor Stator curva de electrica potentiale E = IV. XLIV FWKWDIF vos omittunt stator impedirentur voltage gutta, in stator tempus voltage u≈ E = IV. XLIV FWKWWGON VOLTAGE UP E = IV Frequency F, in Aeris Gap Flux & Frequency F, in Aeris Gap Flux & Frequency F, in Aeris Flux & P. Et decrescit. Et potest ex Torque aequatione, & PHI; Valorem decrescat et motor rotor adductus current I2 etiam decrescit secundum quod necesse ducere ad patitur output torque motricium m Descendit. In addition, si tempus voltage u idem, cum decrementum in F, aer gap magnetica flux & PHI; Et proventus, quod faciam magneticam circuitu satietatem, excitationem surge current ortu causa ferrum damnum, in potentia factor. Ita mutare Frequency F scriptor celeritate, opus ad mutare in stator tempus voltage u simul, ut ponere & PHI; Valorem proxima idem, ut m est fere idem. AC Motor Frequency Imperium Motricium Motor Motricium celeritate est clavis problema ad obtinendum frequency modulationem ac potentia voltage regulator. Sunt multa genera FM fontem. Plerumque communicationis -dc -communication transform circuitu, in circuitu trium tempus current est pelagus pars inverter. Ut ostensum est in Figura II est maxime late usus genus voltage potentia Transistor (GTR) tres-phase inverter principalis principium principium diagram. By the ac -Diode rectifier circuit dc transform to obtain a constant dc voltage Ud, power transistor switching element T1, T4, T3, T6, T5, T2 of three-phase PWM inverter, capacitance C is trying to maintain the input dc voltage inverter Ud as a constant value, therefore, this line is called the voltage type inverter. Inverter switching element T1, T2, T3 is controlled by the triangular wave 1 and generated according to the requirements of speed regulation control has a certain frequency and voltage amplitude of the sine wave 2, through the comparison of the wave 1 and 2 to generate continuous, 3, isometric and wide range of rectangular pulse as control the on-off control signals. Sic vicit tria coetibus in output de inverter cum III similes rectangulum pulsum waveforms, waveform in coegi motricium, eius actio est equivalent ad IV tres-phase sine intentione. Ex supra disputationem, in inverter est key ut animadverto frequency conversionem regulando inverter control finem consequi requiritur imperium waveform III. In realization of waveform), nunc late adoptavit per vector mutatio potestate. Figura III est instantia de AC servo imperium system diagram, ratio ex duabus partibus, potestate converter et imperium platform. Power converter et constans rectifier et inverter, in partes rectifier est initus trium-phase alterna current in directum current (DC), ut ostensum est in Figura III superius sinistram; Inverter est directum current (DC) in requiratur secundum postulationem de potestate signum trium-phase alterna current (n), nunc saepe utitur novum genus altus potestate IPM, ut ostensum est in III superioris. Et controller suggestus in hardware de ratione DSP + FPGA ut ostensum est in Figura III, ut ostensum est in inferiore parte. The FPGA (Field programmable gate array)Devices and DSP (Digital signal processor)'s main function is, together with the software implementation of all control the task scheduling, the processing of input and output signal, the inverter control signal generation, and other control functions, etc. Single-chip microcomputer AT89C52 to realize the digital tube display, keyboard,Used for debugging and parameter Occasus) tum quod administratione de Vide Portus. Limited spatium, detailed munus singulis moduli, hic non est in detail.
