Acoustic Noise Analysis and Reduction of Electric Motors: Using Numerical Electromagnetic, Mechanic and Acoustic Finite Element Method Noise Modelling

In this thesis, the acoustic noise emitted by a small electric outrunner motor, such as the ones commonly used in unmanned areal vehicles, is analyzed using a multiphysics simulation based on the finite element method. The simulation covers the electromagnetic, mechanical and acoustic domain. The electromagnetic simulation is performed in the 2D...
