Stepper Motor Application Circuit Diagram A stepper motor is a type of brushless DC motor designed to divide a full rotation into a big number of precise steps. Unlike typical motors, which rotate repeatedly, stepper motors move in discrete steps, allowing for highly accurate positioning and control. Stepper motors use specialized control methods to achieve better precision than standard variable speed motors, while avoiding the expense and complexity of servo systems. For industrial automation, the term motion control usually means using an electric motor to positively drive the position, velocity, and acceleration of a physical system. Stepper Motor Control Controlling a stepper motor requires a command signal usually generated by a microcontroller or stepper controller, a power signal which is created by the drive, and a motor.
Learn about how to control stepper motors, matching your stepper motor to a stepper drive and other key considerations for stepper motor design.
How to Use Stepper Motors with Arduino Circuit Diagram
A stepper motor requires a number of step pulses to get to your desired position. Also, stepper motor coils are always energized, greatly increasing the holding torque, but turning it forcibly is difficult. In contrast, stepper motors with position closed-loop control detect the rotor position signal and feed it back to the control unit. The system considers a step completed only after receiving the corresponding actual position response and then issues the command for the next winding phase of the stepper motor to step.
