摘要
在分析电机运行原理和应用要求的基础上,引用基于新型逆变器的无刷直流电动机双模式控制方法,设计出无刷直流电动机双模式控制器,基速以下采用双闭环控制方法,基速以上采用弱磁扩速控制方法。仿真和实验验证该方案可行,实现无刷直流电动机在宽速度范围内稳定工作。
Dual mode control method based on a new inverter for brushless DC motor was cited by analyzing the operation principle of brushless DC motor and application requirements. Dual mode controller for brushless DC motor was de- signed, which used dual closed loop control when motor was running below base speed and field-weakening control when motor was running above base speed. The simulation and experiment results show that brushless DC motor can operate in a wide speed range.
