级联式无刷双馈电机在二次方侓负载驱动中的应用

摘要

Based on summarizing the application of quadratic law load such as fan and pump systems,and comparing the current driving schemes,a new driving system for cascade brushless doubly-fed machine was presented,including the machine' s working principle and the speed control scheme.The simulation result proves feasibility of this speed control shchem for the cascade brushless doobly-fed motors.%在总结驱动风机及泵类等二次方负载实际应用的基础上,通过对比目前驱动方案的实际应用效果,提出一种新型级联式无刷双馈电机的新驱动系统.介绍级联式无刷双馈电机原理及其调速原理,设计初步的调速控制方案.仿真结果证实了级联式无刷双馈电机调速方案的可行性.
