چکیده :

Switched reluctance motors (SRMs) are good candidates for high-speed applications because of robust and simple structure both for rotor and stator cores. Optimal design of a high-speed SRM requires a precise multi-physics electromagnetic and mechanical analysis. This paper aims to present the design workflow and performance analysis of a three-phase high-speed SRM with a 6/4 pole combination for vacuum cleaner application considering a coupled electromagnetic-mechanical analysis. The rated continues output power of the proposed SRM at the base speed is 800W. The base speed is 14000rpm, and the maximum achievable speed in the constant power region is 18000rpm. In this work, mechanical analysis including deformations (stress/strain analysis), vibrations and acoustic noise, considering radial forces as the main source of mechanical excitation is presented. Two-dimensional electromagnetic analysis is performed in the ANSYS Maxwell finite element software, and the calculated surface force densities are mapped onto the ANSYS Workbench for three-dimensional mechanical analysis. Results corresponding to each simulation type is presented and discussed.
