What is the difference between stepper motor driver chip and DC motor driver chip? [Copy link]

What is the difference between a stepper motor driver chip and a DC motor driver chip? In terms of input and output? Can a stepper motor driver directly drive a DC motor? What is a linear drive and what is a nonlinear drive? Does a stepper motor driver output a sine wave?

"What is the difference between a stepper motor driver chip and a DC motor driver chip?" Stepper motors and DC motors are two completely different types of motors, with different structures and working principles. Of course, the two driver chips are also completely different. It is recommended that the original poster first understand the structure and working principle of stepper motors and DC motors (including the sub-categories under the two major categories, such as the series-excited, parallel-excited, and compound-excited permanent magnets of DC motors) before considering how to drive them.

OK, thank you

In fact, you can find the corresponding motor driver chip to make a more intuitive comparison. However, you can find the driving principle of the two on Baidu.

First look at the driving principles of the two and you will understand everything. As for the driver chip, there is no such restriction and it can be used flexibly.
