  1. Precise control: Stepper motors move in small steps, which allows for precise control of the motor’s position and speed. This makes them ideal for applications where accurate positioning or motion control is required.
  2. Open-loop operation: Stepper motors can be operated in an open-loop system, which means that no feedback is required to determine the motor’s position or speed. This simplifies the control system and reduces costs.
  3. High torque at low speeds: Stepper motors can generate high torque even at low speeds, which makes them suitable for applications that require high torque at low speeds, such as in robotics or automation.
  4. Easy to use: Stepper motors are easy to use and require minimal maintenance. They do not require complex feedback systems or special control circuits, which makes them a cost-effective solution for many applications.
  5. Repeatability: Stepper motors can repeat the same motion accurately, making them ideal for applications where precise, repeatable movements are necessary.
