Evaluation of the Effects of Propeller Imbalance on PM Motors for Aircraft Electric Propulsion

The large use of electrified aircraft vehicles requires the development of high performance and reliable electric drives. Furthermore, fault tolerant performance plays an important role and control strategies for common faults inherent in the application should be developed. The paper refers to the use Surface Permanent Magnet Synchronous Motors (SPMSM) for the electric propulsion of unmanned aerial vehicles. A numerical approach is proposed for the analysis of the effects of an imbalance of the propellers on the operations and features of the used motors. The results obtained are compared with those deriving from conventional types of eccentricity.
