Stepper motor drive experiment

Stepper motor drive experiment

Purpose

Stepper motor rotation

Theoretical study

The red wire of the stepper motor is VCC, and the remaining 4 are 4 phases. For stepping motor phase control, if phase A is selected, the microcontroller will give high level to the BJ1 pin of the drive board, and low level to the other BJ2/BJ3/BJ4 pins.
