Celeritas DC motricium moderatoris potest control et adjust, scitis? Dicitur per inferius parva faciunt ad vos de mea mutatio modum DC motricium celeritate controller. I. Et armatura intentione: hoc est a torque imperium modum, mutatione armature intentione, ut celeritas mutatio, habet commoda a veloce dynamic responsio, ita idoneus est a lateque de steplless lenis celeritas regulant. 2. Change the dc motor controller: the main magnetic flux by weakening magnetic flux of dc motor controller, let its speed rising from the rated speed, this way belongs to the constant power speed regulation method, on the dynamic response is slower, although can be stepless smooth speed regulation, but the speed range is small. Super omnia, quisque scit quomodo mutare DC motricium celeritate est.
