【摘要】 提出一种新型逆变器结构的无刷直流电机有限元分析方法。分析表明,在保持逆变器容量不变的情况下,基于新型逆变器拓扑的无刷直流电机比普通逆变器结构的无刷直流电机具有更好的弱磁能力,能产生更好的扩速效果,并且还具有结构简单的特点,因而有较好的应用前景。更多还原

【Abstract】 BLDCM with novel inverter topology is analyzed in this paper with the finite element method.The results show that the field weakening ability of such topology is better than conventional inverter topology with a fixed rating of the inverter,thus,a better CPSR is achieved without any changing of the motor rotor.更多还原
