三相无刷直流电机调速系统的驱动设计

Design of Three-phase Brushless DC Motor Driver Circuit Based on DSP

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.

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 controlling, this paper designs a driving circuit of the three-phase brushless DC motor, including power module, signal isolation module, IR2136 logic circuit, driving circuit of the three-phase full bridge and over current protection circuit, etc.
