Industrial Automatic Control Systems and Controllers Annotation << Back Microprocessor Control of Stepper Motor Based on STM32 chip Starostina Ya.K., Kukushkin V.A. This article discusses the modeling of microprocessor control of a stepper motor based on the STM32 chip. The results of modeling microprocessor control of a stepper motor based on the STM32 chip and the given program code can be used for thematic, narrowly focused experiments, and also serve as the basis for building control systems for stepper motors, since by making small adjustments to the circuit and code, you can change the rotation speed or regulate the shaft rotation speed of both a bipolar stepper motor and a unipolar motor. Keywords: stepper motor, microprocessor, microcontroller, driver, control system, microcircuit, modeling. DOI: 10.25791/asu.12.2023.1477 Pp. 41-45.
