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.

Stepper motor control method

Stepper motor is a type of motor that can convert electrical pulse signals into angular displacement of motor. The main control methods are as follows:

1. Full step control

• The most basic control method.
• Each pulse corresponds to the motor rotating a complete step angle.
• The motor rotates smoothly but at a slow speed.

2. Half-step control

• is improved on the basis of full-step control.
• Each pulse corresponds to the motor rotating half a step angle.
• The rotation speed is faster than full step control, but the rotation accuracy is lower.

3. Micro-stepping control

• A control method that further subdivides the step angle.
• By changing the pulse width or pulse phase, the motor can be rotated at a smaller step angle.
• Have the highest rotation accuracy and speed.

4. Current control

• Control the current flowing through the motor to adjust its torque and speed.
• Can achieve smoother rotation and faster response.
• Suitable for high-precision and high-dynamic applications.

5. PID control

• A feedback control method that adjusts the motor by measuring the error between the actual position of the motor and the target position of torque.
• can improve the stability and accuracy of the motor.
• Commonly used in complex and highly dynamic applications.

6. Vector control

• An advanced control method that uses the mathematical model of the motor to optimize its performance.
• Can achieve higher torque, speed and efficiency.
• Suitable for applications requiring high performance and reliability.
