-phase with current at any moment, the torque of the motor is a loss. The rotation of the stepper motor is also the result of the electromagnetic pole and the permanent magnet pole force, but the polarity of the electromagnetic pole is realized by the driving circuit control.We can make an experiment like this to get in the m
effective volume of the motor * number of turns * magnetic density (only linear state is considered). Therefore, the larger the effective volume of the motor, the larger the number of turns of the excitation, the smaller the air gap between the stator and rotor, the larger the motor torque, and vice versa.

!! Come from Elecfans : http://www.elecfans.com/article/88/131/194/2015/20151010385722.html[Guide] Stepper motor in the control system has a wide range of applications. It can convert the pulse signal into angular displacement and be used as electromagnetic brake wheel, electromagnetic differential, or angular displacement generator.First, preface:Stepper Motor h
From: http://www.eepw.com.cn/article/73889.htm Stepper motor is an electromechanical component that converts an electrical pulse signal into an angle displacement or linear displacement. The input value of the stepper motor is a pulse sequence, and the output value is the corresponding incremental displacement or step
Stepper motor principle and drive 1, stepper motor is a special motor used as a control, the electrical pulse signal converted into angular displacement or linear displacement of electromechanical components. The input amount of stepping

Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the load changes, when the stepper
Many users mistakenly think that the higher the stepper motor driver subdivision, stepper motor precision is higher, in fact, this is a wrong idea, such as stepper motor driver subdivision can reach 60,000 pulses a turn, and
First, the general introduction:Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the load changes, when the
BEIJING Stepper Motor Drive where is it sold? How about the price? Stepper Motor Driver now more and more manufacturers, many manufacturers through the network to attract customers, especially the current era of Internet e-commerce prevalence, but these need us to choose which step
Stepper motor is a kind of electromagnetic mechanical device which transforms electric pulse into corresponding linear displacement and angular displacement. With a fast start-up stop capability, when the motor load does not exceed the torque he provides, the input pulses can be used to control his stop and start in a flash. The step angle and speed of the
