摘要
介绍了以TMS320LF2407A DSP为核心的四相无刷直流电动机开环控制系统的硬件设计,阐述了四相无刷直流电动机开环控制软件实现方法。并给出了MOSFET管的驱动电路图,分析了两个霍尔位置传感器检测到的转子位置信号和DSP输出的4相PWM触发信号。经12V/120W的四相无刷直流电动机实验证明,该系统控制电路简单、系统能够稳定运行,成本低。
The hardware design of four-phase brushless DC motor open-loop control system based on TMS320LF2407A DSP was introduced in this paper,the realizable methods of software were explained in detail.And the MOSFET drive circuit was presented.Analyze two hall sensors signals and PWM output signal.The test result of the prototype of 12V/120W indicates that the performance of this control system is simple,stable.Besides,it is a low cost system.
