What is a stepper motor?

Stepper motors are motors that rotate in precise increments, usually at a fixed angle at a time, and can convert electrical energy into precise rotary motion. They are typically used in control applications that require precise position control and repeatability. Examples include printers, scanners, camera lenses, etc.

The advantages of stepper motors

Stepper motors allow the motor shaft to rotate to the desired position by energizing the phases in a specific sequence. Stepper motors offer several key advantages over other types of motors:

• Precise position control: stepper motors can move in precise steps, resulting in precise control of position, speed, and acceleration.
• Repeatable positioning: when powered on, the stepper motor will always move the same number of steps, allowing repeatable positioning.
• High torque at low speed: Stepper motors can provide high torque in low-speed applications.
• No power-holding torque: When the stepper motor is powered off, it locks into place, holding the load firmly in place.

Conclusion

In general, stepper motors are multifunctional motors, ideal for applications with low speed but with speed and position control needs, high precision, good reliability, and easy control. These advantages also make them widely used in a variety of applications that require high-precision motion control.
