How Stepper Motors Achieve Linear Motion?

  1. Use Screw

A common method of converting the rotary motion of a stepper motor into linear motion is to use a screw. Attaching a stepper motor to a threaded shaft that interacts with a nut-like positioner converts rotational motion into linear motion.

  1. Use Guide Rails

Another common method is to use guide rails. The guide rail can convert the rotational motion transmitted by the stepper motor into linear motion. Guide rails are usually made of metal rods or similar materials that ensure continuity and stability of linear motion. Guide rails can be used in many industries, including robotics, CNC machine tools and medical equipment.

  1. Use Belt

The third method is to use straps. By attaching a stepper motor to a pulley and wrapping a strap around the pulley, rotational motion can be converted into linear motion. This method requires ensuring tight contact between the strap and the wheel at all times, and using appropriate tensioners to maintain strap tightness and normal movement.

In summary, the above are three common methods for converting stepper motor rotary motion into linear motion. Depending on the specific application scenario and actual requirements, different methods can be selected to achieve the best results.
