无刷直流电动机在集成电机推进器中的应用及设计

Design and Application of Brushless DC Motor in Integrated Motor Propulsors

集成电机推进器中的推进电机种类较多,无刷直流电动机由于其功率密度高、起动转矩大等优点而受到重视。5.5 kW级表面突出式和内置切向式转子结构无刷直流电动机的设计、分析以及性能比较,对于无刷直流电动机在集成电机推进器中的进一步应用具有一定的实际指导意义。

Integrated motor propulsor （IMP）, a kind of small and modular propeller,is used in the fields of underwater robot and weapons,brushless DC motor （BLDCM） has been widely adopted in IMP for recent years because of its special performances such as high power density, large starting torque, etc. The design and analysis on surface-mounted permanent magnet （ SPM ） and interior permanent magnet （ IPM ） BLDCM can well guide the further actual applications of BLDCM in IMP.
