摘要
针对某旋翼无人机用高功率密度伺服驱动电机的技术要求,通过分析与有限元仿真优化,得出了内转子表贴式永磁转子结构相对更适合于平衡功率密度、效率和转矩波动等指标之间关系的结论。据此设计了一款具有高功率密度、高效率以及较低转矩波动的伺服驱动电机,通过样机进行了试验验证,其性能指标满足设计要求。
Aiming at the technical requirements of a high power density servo drive motor for a rotor UAV,through analysis and finite element simulation optimization,it is concluded that the surface-mounted permanent magnet rotor structure of the inner rotor is relatively more suitable for balancing power density,efficiency,torque ripple and other indicators.Based on this,a servo drive motor with high power density,high efficiency and low torque ripple was designed,and the prototype was tested and verified,and its performance index was satisfied with technical requirements.
