摘要
针对长期以来人们在分析无刷直流电动机的换向规律时只能沿用一套固定的真值表而无法进行更深入的研究这一问题，提出了无刷直流电动机电流逻辑解析结构的数学模型，在此基础上，推出了电机不同接法下的最佳换向逻辑解析结构，分析了由此产生的对电机的扭矩、速度及功率密度等性能指标的影响，并对 １
Due to the problem that only an invariable truth table can be used in analyzing the swifting law of brushless DC motor,it is difficult to adopt different swifting structures and research their effects to motor performance.In view of this situation,a mathematics model of brushless DC motor is firstly presented in this paper,then tffects caused by changing swifting logic structures are analyzed in depth.The experiment result and analysis based on a 30kW permanent magnet brushless DC motor for a electric vehcle are given in the end.
