  • The application and development of stepper motor control system are summarized

    introduction:Stepper motor​It is an open-loop control motor that converts the electrical pulse signal into angular displacement or linear displacement,It is the main executive element in modern digital program control system,Extremely widely used。。In the case of non-overload,Speed of motor、The position of the stop depends only on the frequency and number of pulses of the pulse signal,It is not affected by changes in load,When the stepper driver receives a pulse signal,It drives the stepper motor to rotate a fixed Angle in the set direction,call“Step Angle”,Its rotation is carried out step by step at a fixed Angle。The amount of angular displacement can be controlled by controlling the number of pulses,So as to achieve the purpose of accurate positioning;At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency,Thus to achieve the purpose of speed regulation。 Stepper motor is a kind of induction motor,It works by using electronic circuits,It turns direct current into
