A stepper motor is a mechanical device that directly converts electrical pulses into angular positions. The angle depends on the number of pulses, and it, together with other supporting stepper motor drive devices, forms a simple and low-cost open-loop system for control.
The word 'mixed' means to combine or combine. A stepper motor is a mechanical device that directly converts electrical pulses into angular positions, and the angle depends on the number of pulses. The stepper driver is controlled by the latest 32-bit ARM processor. This digital driver has peripheral subdivision, current, and auxiliary function dialing, which users can freely set according to their needs. Together with other supporting stepper motor drive devices, it forms a simple and low-cost open-loop system for control.
