Design and Application of Brushless DC Motor in Integrated Motor Propuisors

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.
