What is STK672-440B-E?


This is 2-phase Stepper Motor Driver.

A stepper motor is a type of motor that moves in precise, incremental steps. It is designed to rotate a specific number of degrees or steps for every input pulse it receives. Stepper motors are used in a wide range of applications that require precise motion control, such as in robotics, 3D printing, CNC machines, and automation systems.

[ Detailed Data ]

There are two main types of stepper motors: bipolar and unipolar. Bipolar stepper motors have two coils that must be energized in a specific sequence to create movement. Unipolar stepper motors have four or five coils that can be energized in a specific sequence to create movement. Both types of stepper motors can be controlled using pulse signals that determine the direction and speed of rotation.
