Types of Stepper Motor Drivers

An Overview of Stepper Motor Drivers and Their Types

A stepper motor is a brushless DC electric motor that turns in steps, with input in the form of programmed energization of the stator windings and output in the form of discrete angular rotation. The defining characteristic of a stepper is its shaft, which rotates by performing steps; that is, by moving a fixed number of degrees. Stepper motors can also divide a full rotation into an equal number of steps. If the motor is appropriately sized for the application, its position can be commanded accurately without any feedback mechanism. This is attributed to the stepper’s internal structure, where the exact angular position of the shaft is known by simply counting how many steps have been performed, with no need for a sensor. This feature also makes it fit for a wide range of applications, including medical devices, robotic arms, and aerospace and defense applications.
