Application of stepper motors:
Stepper motors are widely used, it is used for precision control, used in medical equipment, 3D printers, industrial precision control, automation equipment and so on.
Alternatively, stepper motors can be used in any mechanism that requires precise control and rotational/linear motion.
Advantage of stepper motors:
Even without a closed loop encoder/feedback system, this motor can achieve precise control and has no brushes. Therefore, there are no electromagnetic interference and spark problems. Also in some cases they can replace DC brushed/brushless motors.
The stepper motor is easy to control by the driver, which has established its important position in the field of precision control.
1. Precise control and programmable
2. No electromagnetic interference and sparks
3. The volume is relatively small
4. Reasonable price
5. Low noise
6. Long service life
