Stepper motor est quaedam pulsus electrica in motum actus angularis. Cum stepper motor agitator pulsus signum accipit, movens gradatim agit secundum directionem puncti fixi (vocatur 'gradus Anglus'), eius rotatio ab Angulo gradatim fixi fundatur. Potest moderari pulsuum numerum obsessio angulari, ut finem obtineat accuratae positionis; Itemque frequentiam moderandi pulsum ad celeritatem et accelerationem motricium refrenandam, ita ut finem moderandi assequatur. Gradivus motor potest esse quasi imperium cum motore speciali, utens nullo errore coacervato (Accuracy of 100%) Characteristics, late in omnibus generibus ansa apertae ditionis. Now more commonly used stepping motor including reactive stepper motor (VR）, permanent magnet stepper motor (PM), hybrid stepping motor (HB）And single-phase stepper motor, etc. General for two phase permanent magnet stepper motor, torque and volume is small, step Angle is commonly 7. 5 or 15 degrees; General for three-phase reactive stepper motor, which can realize large torque output, stepper Angle generally to 1. 5 degrees, but the noise and vibration are very big. Reactive stepping motor rotor magneticus ambitus factus ex materiis magneticis mollibus, campus multiphase flexae statoris, torques ex mutatione permeabilitatis
