What does a stepper motor do?

A stepper motor is a brushless, synchronous electric motor that converts digital pulses into mechanical shaft rotation. Its normal shaft motion consists of discrete angular movements of essentially uniform magnitude when driven from sequentially switched DC power supply.

A stepper motor is an electromechanical device that converts electrical impulses into precise mechanical motion. The motor is called a "stepper motor" because it moves in small, precise steps, rather than rotating continuously. This makes stepper motors ideal for a variety of low-speed and high-precision applications.

Application of stepper motor

Stepper motors are used in a wide range of applications and are an excellent choice for low-speed movement and high-precision applications and are commonly used in the following areas:

  • Robotics: Stepper motors are commonly used in robots for precise positioning and control of motors.
  • Printing: Stepper motors are used in the printer to control the movement of the print head and the paper feed.
  • CNC machines: Stepper motors are used in computer numerical control (CNC) machines for the precise positioning of cutting tools.
  • Medical devices: Stepper motors are used in medical devices, such as CT scanners and MRI machines, for precise control of the motion of imaging equipment.
  • Position control: Stepper motors are used in position control applications, such as elevators and actuators, to control the precise positioning of moving parts.


Stepper motors are electromechanical devices that convert electrical pulses into precise mechanical motion. They are used in a wide range of applications, including robotics, printing, CNC machines, medical devices and position control. Stepper motors are characterized by their ability to move in small, precise steps, making them ideal for precise position control applications. Whether you are building a robot or designing a precision position control system, stepper motors are a versatile and reliable solution for your needs.
