stepper motor driver circuit is a circuit that makes the stepper motor run smoothly by providing the necessary voltage/current.
One point to note in stepper motor positioning is that the positioning of the stepper motor is precisely achieved with the help of digital control. The stepper motor rotates by the pulse signal of the drive circuit synchronization controller. The stepper motor driver receives pulses from the controller and converts them into stepper motor rotation.
A stepper motor driver is a brushless motor that operates on a pulsed current. In a pulsed current, each pulse causes a rotor to rotate to a fully rotated portion. Servo motors are generally suitable for a wider range of applications, especially when precise motion is required, but stepper motors may be a useful alternative, depending on the application.
Stepper motor drivers are robust, economical and very suitable for digital drives and applications without closed-loop feedback. They are usually used for rotating hard drives, printers, robots, CNC machines, and so on.
The basic elements of the stepper motor drive circuit are:
1. Controller (microcontroller or microprocessor)
2. Driving chip for controlling and processing motor current
3. power supply device
4. All kinds of equipment, such as radiator, switch and so on.
Note: the establishment of stepper motor driver is more to choose the right power supply and driver, and the choice of microcontroller is secondary.
