【摘要】 步进电机作为执行元件，是机电一体化的关键产品。随着微电子和计算机技术的发展，步进电机的需求与日俱增，在各个国民经济领域有重要应用价值。步进电机在生产生活和工程实践中已被广泛地应用，但步进电机并不能像普通的直流电机与交流电机一样可在常规下使用。它必须由双环形脉冲信号、功率驱动电路等组成控制系统方可使用。通过对步进电机的原理、控制电路的设计和制作进行详细阐述，以期培养学生整体电路设计、调试和分析能力，以及工程案例实践、总结和归纳等能力。更多还原

【Abstract】 As an actuator, stepping motor is the key product of mechatronics. With the development of microelectronics and computer technology, the demand for stepping motor is increasing day by day, which has important application values in various fields of national economy. Stepper motor has been widely used in production, life and engineering practice, but it is not like ordinary DC motor and AC motor that can be used under normal conditions. It must be composed of double ring pulse signal and power driving circuit before it can be used in the control system. In this paper, the principle of stepping motor and how to design and manufacture the control circuit are described in detail, so as to cultivate the students’ ability of overall circuit design, overall circuit debugging and analysis, engineering case practice, summary and induction.更多还原
