【 摘 要 】

Results from recent acoustic and vibration experiments with small electric motors are presented. The results are compared with finite element analysis and analytical predictions. The relevance of electric motor noise to the overall noise produced by small quadcopters is highlighted. Progress toward quiet loading approaches is discussed.
