基于切换的步进电机驱动力矩的研究

摘要

Bank caisse intelligent handover system is set up based on RFID radio frequency technology, wire Internet and wireless Internet technology. It can not only promptly collect, upload and at any time read the information of the caisse handover chain, but also provide safe and reliable certification of escort officer' s identity, dynamic surveillance of escort process, audit and supervision management to realize the automation and electronic intelligence of bank caisse management.%在采用切换控制的基础上,分析目前步进电机驱动存在的问题,并提出采用高低压驱动和改进型续流回路来提升步进电机输出转矩的方案,现场实验结果表明此方案输出电流小、力矩大,很好地改善了步进电机的驱动性能.
