nema 23 three-phase long stepper motor

- Jan 26, 2018 -

Stepper motor general pursuit of positioning accuracy and torque output, efficiency is relatively low, the current is generally larger, and harmonic components of high, current alternating frequency also changes with the speed, so the stepper motor generally have a fever, and the situation than the general AC motor serious.According to the different modes of excitation (the old standard is called excitation), it can be divided into series excitation DC motor, shunt excitation DC motor, excitation DC motor and compound excitation DC motor. Due to different excitation modes, the regularity of stator magnetic flux (generated by the excitation coil of the stator magnetic pole) is different.
