What’s the difference between servo motor and stepper motor?

Servo motors and stepper motors are both widely used in various applications, but they have distinct characteristics that set them apart. Servo motors are closed-loop systems that utilize feedback mechanisms to achieve high precision and accuracy in position, speed, and acceleration control. They are capable of operating at high speeds while maintaining consistent torque, making them ideal for applications that require precise and dynamic movement, such as robotics and CNC machines. On the other hand, stepper motors are open-loop systems that move in discrete steps based on electrical pulses. They are simpler in design and more cost-effective, offering precise positioning at low speeds, which is beneficial for applications like 3D printing and medical devices. While servo motors provide higher accuracy and performance, they come with higher costs and complexity due to their feedback systems and advanced controllers. Stepper motors, in contrast, are easier to implement and control, making them a popular choice for applications where high precision at low speeds is sufficient.
