What is stepper motor drivers?

Drivers of a stepper motor may vary in characteristics and complexity. Most
of the motor types can be connected to modern drivers, and a user can
easily configure it at the time of installation. Large motor drivers are usually
simple drivers as compared to others. Stepper drivers are drivers circuit,
and it controls the stepper motors operations. Drivers send current through
different paths to the motor, and all drivers are used to improve the motion
of the motor.

Typically all 3D printers use a stepper motor to maintain the
axis position. They build a surface and bring accuracy in positioning the
print head.

Stepper motors driver contains many components, and their duty is to
control step command pulses, that comes from the controller of a machine,
and it converts them into required on/off pattern. The motor needs a
command to turn back and run from one direction to another direction,
and this pattern energizes the phase in a defined manner and helps the
motor to work more efficiently.

The important note is that the stepper motor driver has little intelligence in
it because the driver has no concern with the axis position and the distance.
This ability is in the machine controller. Typically the driver performs in only
two ways; that's called primary functions of the driver. One is to control the
phase current, and the other is to sequence the phase. Big motors may
need an extra controller to perform such duties.

It is essential to buy the ompatible driver according to your motor size and requirements.
