With application of the special working principle, and has many virtues and advantages of stepper motor in use showed the following characteristics: the characteristics of a: stepper motor torque declines with the increase of rotational speed, this is because at the time of motor rotation, the motor of each phase winding inductance would form a reverse electromotive force, the higher the frequency of the motor rotation, the greater the back emf. Sub actione electromotive vis, torque ex motricium et decrescit cum incremento gyratoris frequency. Mores II: Gradus motor in humilis celeritate conditio potest adhuc munus recte, sed celeritas est excelsum, potest incipere currit recte, simul etiam potest producere abnormes sonitus. Hoc est quia motor non-onus startup frequency de technica parametri, si pulsus frequency est altior quam valore, motor non satus proprie. Tres habet, in perficientur de stepper motricium valde altum, potest providere precise imperium oeconomicae operationem, in usum non opus est suscipio sustentationem, facile ad imperium, ut magis serve necessitatibus utendi munus. Motor est maxime in his quae sunt, per introducendis in motricium, ut possis invenire, hoc est valde distinctiva motricium, habet multa characteres in operationem et functionalis facies. Pelagus Products: Stepper motricium, Brushless motor, Servo Motor, Pentium Motor Coegi, fregit motricium, linearibus motricium et alia exempla monstrabit in stepper motricium et alia exemplar.
