【摘要】：脉动的径向电磁力导致的定子振动问题阻碍了磁阻电机的推广应用。该文研究了一种利于减小无轴承开关磁阻电机(bearingless switched reluctance motor,BSRM)定子电磁振动的悬浮运行控制策略。该控制策略在保证电机转子悬浮所需悬浮力一定的前提下,以减小定子极受到的径向电磁力为控制依据。基于悬浮运行原理和数学模型,叙述了减振控制策略的基本原理;推导了主绕组电流、悬浮绕组电流、开通关断角等电机相关控制参数的计算方法;并给出了系统控制框图。仿真和实验结果均证实了新的控制策略不仅能实现电机的稳定悬浮旋转运行,同时有利于减小BSRM定子电磁振动,验证了理论分析的正确性和可行性。
[Abstract]:The vibration of stator caused by pulsating radial electromagnetic force hinders the popularization and application of reluctance motor. Bearingless switched reluctance motor. The control strategy of the electromagnetic vibration of BSRM stator is proposed, which can guarantee the suspension force of the motor rotor. On the basis of reducing the radial electromagnetic force on the stator pole, the basic principle of vibration reduction control strategy is described based on the suspension operation principle and mathematical model. The calculation methods of motor control parameters such as main winding current, suspension winding current, turn-off angle and so on are deduced. The simulation and experimental results show that the new control strategy can not only realize the stable suspension and rotation of the motor, but also reduce the electromagnetic vibration of the BSRM stator. The correctness and feasibility of the theoretical analysis are verified.
