摘　　要：为实现EFP093电动燃油泵各项性能指标,在提高燃油泵泵体组件效率的同时,必须对油泵中电机效率加以提高,由于该电动燃油泵应用的是小功率直流电机,而其涉及到材料、电机工作原理和基本电磁参数等多个方面的内容。笔者探讨的就是从这几个方面入手对电机效率予以改善,进而达到提高电动燃油泵总体效率的目的。To achieve the EFP093 electric fuel pump performance, at the same time improving the performance of fuel pump subassembly, must improve the fuel pump motor efficiency. Because the application of the electric fuel pump is low-power DC motor, which relate to materials, electrical works, basic electromagnetic parameters and so many aspects. Discussion of this article is to improve the motor efficiency via these aspects, and improve overall efficiency of electric fuel pump.
