三相无刷直流电机调速系统的驱动设计

摘要

By using IR2136 (International Rectifier) to design a three-phase brushless DC motor driver circuit based on TMS320F28335 floating-point processor and implementing positive-negative rotating and speed con⁃trolling, this paper designs a driving circuit of the three-phase brushless DC motor, including power module, sig⁃nal isolation module, IR2136 logic circuit, driving circuit of the three-phase full bridge and over current protec⁃tion circuit, etc.%　　以TMS320F28335浮点型处理器为控制器，采用International Rectifier公司的IR2136作为驱动芯片，设计了三相无刷直流电机的驱动电路，实现三相无刷直流电机调速及正反转控制，其中包括电源模块、信号隔离模块、IR2136逻辑电路、三相全桥驱动电路及过流保护电路等。
