【Abstract】 The design and simulation of a PMSM used in the drive system of stratosphere airship propeller was introduced in this paper.In this system,the stator of the motor adopted fractional-slot winding to reduce cogging torque,and the rotor used insert permanent magnet(IPM).The reducer employed the design of helical planetary gear.Meanwhile,electromagnetic and thermal simulation design were also used to ensure the reliable performance of the high power density motor system in near space.更多还原
