该步进电机驱动器又称为EasyDriver，EasyDriver能够为两级步进电机提供大约每相750mA（两极一共1.5A）的驱动。它默认设置为8步细分模式（所以如果你的电机是每圈200步，你使用EasyDriver时默认为每圈1600步），更多细分模式可以通过将MS1或MS2两个接脚接地进行设置。这是一种基于Allegro A3967驱动芯片的细分断路器。对于此设计的完整规格，请查阅A3967的参数表。它的最大每相电流从150mA到750mA。可以采用的最大驱动电压大概是30V，其中包括板载5V的调压器，所以只需要一个电源。质优价廉，这玩意儿只要十几美元，比你自己制作电路板更便宜。步进电机驱动器设计特色：· A3967 Microstepping Driver· MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)· Compatible with 4, 6, and 8 wire stepper motors of any voltage· Adjustable current control from 150mA/phase to 700mA/phase· Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

基于TMS320F28035芯片为控制核心的空间矢量异步电机变频器 我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心，通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法，并对其进行了优化。采用检测反电势的方法省去了昂贵的光电编码器，大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法，使我们的变频调速器可以在电网条件恶劣的乡村山区工作，由此该变频器已被一家民用水泵生产企业预订。关键字 变频器 TMS320f28035 IPM SVPWM In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVPWM (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.
