基于STM32的一种步进电机系统的设计

摘要

A stepper motor control system based on STM32 controller is introduced in this paper.The system uses the S type function model for the acceleration and deceleration motion of the stepper motor,which effectively avoids the loss of step and overshoot of the system during the high speed movement.In the system,the system can ensure the accuracy of the system in high frequency and low frequency motion by adjusting the frequency division coefficient.In the system,the vibration and noise of the system can be reduced effectively by adjusting the subdivision of the motor drive chip.The experimental results show that the system has low cost,stable operation and high reliability.%文中介绍了一种基于STM32控制器的步进电机控制系统,该系统对步进电机的加速和减速运动采用了S型函数模型,有效的避免了系统在高速运动时出现的失步和过冲现象.在系统中通过调节分频系数保证了系统在高频和低频运动时的准确性,在系统中通过调节电机驱动芯片的细分能够有效地降低了系统的振动和噪声.实验结果表明,整个系统成本低、运行平稳、可靠性高.
