【摘要】 叙述了从传统的有刷直流电机到当前被广泛应用的无刷直流电机(BLDCM)发展的巨大进步,同时也分析了BLDCM传统控制系统存在的问题与不足,并基于TI C2000系列数字信号处理器(DSP)芯片及DRV8301前置驱动器芯片设计了一套解决这些问题与不足的BLDCM无位置传感器驱动控制系统。给出了该控制系统主要电路设计及主程序流程。该方案相较于传统控制系统方案具有运行稳定性好、控制性能优越、成本低、体积小、易于使用等诸多优点。更多还原

【Abstract】 The great progress in the development of brushless DC motor(BLDCM) from the traditional brush DC motor to the widely used BLDCM was described. Based on the TI C2000 series digital signal processing(DSP) chip and DRV8301 front-drive chip, a set of BLDCM sensorless drive control system to solve these problems and deficiencies was designed, and the main circuit design and main program flow were given. This control system scheme had many advantages such as good operation stability, superior control performance, low cost, small volume, and easy to use compared with the traditional control system scheme.更多还原
