What are the control methods of stepper motors?

The main control methods of stepper motors include: full step control: each pulse corresponds to a step angle, and the rotation is smooth but slow. Half-step control: Each pulse corresponds to half the step angle, and the rotation speed is fast but the accuracy is low. Micro-stepping control: subdivide the step angle to achieve higher accuracy and speed. Current control: Control current to adjust torque and speed to achieve smooth rotation and quick response. PID Control: Feedback control to improve stability and accuracy for complex and highly dynamic applications. Vector Control: Optimizes motor performance for higher torque, speed and efficiency for high performance and reliability applications.

The difference between stepper motor and servo motor

The main difference between stepper motors and servo motors is: Working principle: Stepper motors rotate through pulses, while servo motors rotate precisely through feedback control. Control mode: stepper motors rely on pulse signals, and servo motors rely on closed-loop control. Features: Servo motors have high precision, large torque, and smooth speed. Stepper motors have limited step accuracy, low torque, slow speed, and obvious vibration noise.
