摘要
在分析压电马达运行原理和等效电路的基础上,设计了一种基于LC谐振原理的压电马达驱动电路。采用TMS320F28035 DSP为电路的控制核心,利用全桥逆变和LC谐振产生驱动信号,并通过Multisim软件对驱动电路进行仿真分析。实验结果证明,该驱动电路能够满足驱动压电马达的要求,提高光纤对轴系统的定位精度,同时实现系统的小型化设计。
Following the analysis of the operating principle and equivalent circuit of the piezoelectric motor, a driving circuit based on LC resonance principle is designed. The DSP TMS320 F28035 is designed as the control core in the circuit,the driving signal is generated by using full bridge inverter and LC resonance, the driving circuit is simulated by Multisim. It is shown that the drive circuit can meet the drive requirement of the piezoelectric motor, it improves the positioning accu-racy of fiber axis system and realizes the miniaturization design of the system.
