DC motricium potest magnetica flux, et mutare in armatura voltage regulator circuitu resistentia modum celeritatis temperatio, sed mutare armature resistentia celeritate potestate, ut in Metor Methoti, et utitur in motricium, non solum potest esse in motricium, non solum potest esse in motricium, ut non solum potest esse in motricium, ut non solum ad facultatem ad motricium. In NC machina tool fusum coegi, DC Fusum motor celeritate imperium plerumque utitur thyristor celeritate imperium ratio et transistor pulsum latitudinis modulatum (脉宽调制) imperium ratio. A magnetica fusum motor celeritate regularicius Circuit potestas maius et requirere constans potentia celeritate range quanta possibile, ita communiter se excitatur motricium, excitationem curuantur et ruminatam in potentia. Control circuit of excitation current is given, the armature voltage feedback, excitation current feedback PI regulator after comparing three groups of signal input, the output of the regulator through the voltage/phase converter, control of thyristor trigger pulse phase, adjust the current size of exciting winding, realize the constant power weak magnetic speed of the motor. Secundo, quod pressura regulanting celeritas regulanting celeritate imperium circuitu est similis DC feed servo ratio, etiam factum est de celeritate ansam et current imperium ratio, habet bonum static et dynamic index, potest utor overload facultatem et dynamic in magna gradus, quod est bonum, quod est in motricium in magnis, quod est in primis, quod est in Motricium in magna gradus, quod transitus processus est motricium in magna, potest utor quod est bonum, quod est in motricium in magna, quod est in Motor in magna, quod est in processus. Per Imperium DC variabilis celeritas fusum motor armature voltage implementation. Tres, pelagus circuitu et operantes principium NC apparatus instrumentum partes, requirere fusum positivum & negans secare potest esse quod magna fieri potest, ut prohibere et mutare celeriter. Fredle DC motricium driving machinam adoptat tres-tempus pontem typus anti parallel logica et circulatio reversible celeritate imperium ratio. Pelagus circuitus est ostensum est in Figura I. Quisque paro ex tribus, tempus pontem generis inverter pontem formationem duo coetibus ad vicissim polarity parallel Converter pontem per AC potentia. Vicissim verticitatem parallel circuitus potest animadverto motricium positivum et negans feedback ad electrica et dynamic braking. Ut aliquando patitur coetus pontem via opus alius pontem itinere obstructionum logicam imperium circuitu. Cum motricium deinceps motus, VT1 pipe opus in rectifier statu, praebet positivum recta current; Motor Reverse motus, VT2 pipe opus in rectifier statu, et providere versa recta current, motor in a incipiens, celeritas imperium, tres quadrantes. From forward motion to turn to reverse when motor electric state, speed instruction from is becoming negative, inverter VT1 tube into the state, the motor armature inductance energy storage to maintain current in the circuit direction remains unchanged, still in a state of electric motor, the armature current has been gradually decreasing. Cum armature current redigendum ad nulla, oportet facere VT1 pipe et VT2 est clausus, tunc liberum ad gyrari motor in inertia effectus. After security delay VT2 tube into the active state of inverter, motor working in state feedback power brake, the mechanical energy back to the grid, speed decreases rapidly, after the speed drop to zero, VT2 rectifier tube into the state, reverse starting motor, so as to complete the work from a quadrant to the third quadrant of the conversion. Just faciunt VT1 pipe et VT2 loco potestate, quod est intellexit motricium ex inversione ad deinceps transformatio processus. Quattuor principalis circuit control requisitis ut quando tantum patitur coetus pontem via opus, alius coetus pontem via obstructionum, logicae imperium circuitu. Using the logic control circuit detects whether the armature current of the circuit to zero value, and judge the direction of rotation, provide VT1 pipe and VT2 is allowed to open the signal, make a set of thyristor at work, another group of thyristor trigger pulse were blocked, so as to cut off the positive and negative between two groups of thyristor current path that may occur. Quapropter logicae circuitus satisfacere sequentia (a) omni momento liceat paro thyristor trigger signum. (II) nisi cum opus, quod coetus ex Thyristor post current nulla, ut inrita trigger signum, ut ne cum thyristor inverter, current non nulla, evacuantur felis per signum per inverteris subversio malfunction. (III) nisi cum opus, quod coetus ex Thyristor est omnino clausit, potest aliam paro of Thyristor trigger signum, ut ne magnus circulationem. (IV) quis paro of thyristor conduction, ut ne output voltage et motor curvis electro electromotive vis produci in eodem directionem, ad nimium electricity. Haec charta ex charta rete
