First is speed. Stepper motors operate considerably slower than servo motors.

The second difference lies in motor resolution; servo motors feature higher resolution. A linear stepper motor is a type of motor that generates linear motion directly without transmission components such as lead screws or belts.

With this introduction, it is easy to understand the advantages of linear stepper motors compared with servo motors. Since transmission belts (or lead screws) are eliminated, the working head achieves faster start and stop responses. Without transmission mechanisms, motion distortion during power transmission is completely avoided.
