Abstract
- This paper first studies the electromagnetic force and vibration characteristics of the permanent-magnet-assisted synchronous reluctance machines (PM-SynRMs). First, an analytical method to calculate the radial force is proposed based on the Maxwell stress tensor method. The temporal and spatial orders of radial force are obtained by two-dimensional fast Fourier transform, then the combination of stator slots and rotor virtual slots of PM-SynRMs is proposed to give a guideline for the initial design of PM-SynRM to achieve low noise and vibration. A PM-SynRM is designed and a multiphysics model for electromagnetic vibration is established. The radial and tangential force under no-load and load conditions are calculated by finite element method, and then compared with the analysis results. Modal analysis is implemented to capture the structural parameters of the stator. Based on the proposed multiphysics model, the vibration responses under both no-load and load conditions are calculated through modal superposition method. Finally, a PM-SynRM is built and vibration test is performed to investigate its vibration characteristics. [ABSTRACT FROM AUTHOR]
