AN-1153 Stepper Motor Controller

Stepper motors are among the most widely used actuators for high precision motion. They are used in routing systems, 3D printers, robots, etc. For similar applications, servo motors were used in the past; but today, compared to stepper motors, they have higher costs and complexity because of the additional components needed to make them (position sensors and error amplifiers etc.). This is why today, the ideal choice is often a stepper motor because it’s simpler to control it and it has good accuracy, good torque, moderate speed, and a low cost.
