摘　　要：针对稀土永磁(REPM)无刷直流电机(BLDCM)组成原理及其驱动的特殊性,进行了无刷直流电机缺相故障分析及仿真;设计了大功率航空无刷直流电机电子保护装置。该装置能对电机缺相、过流、过压、欠压故障相做出判断并进行保护,通过LCD显示过流大小和缺相相,并上传故障代码。Aimed at the particular constitute and driving principle of Aero REPM- BLDCM, the criterion to the fault of phase-open is deduced from theoretical analysis and simulation result,so that the electronic protector for aero REPM- BLDCM is designed. The protector has a reliable performance to filter out the faulted phase, and provides the excessive value of phase current,overloaded voltage on I.CD screen,and then error codes are uploaded.
