Abstract
The design and ergonomics appeal of the consumer products is limited by the size, weigh and, power versus ratio of the high speed motor. It is known as the heart of these range of consumer products. Often, many of these products stand out from each other in comparison to either its performance, ergonomics, features, aesthetics and more recently noise that is defined by sound power as the standard of quality living is elevated. This thesis presents the design, advance analysis and modeling of high-speed motor components. Firstly, the motor’s sub-assemblies from Production were studied, and the trailing edge end impeller rim dynamic runout was analysed to be one of the contributing factors to the broadband noise of the motor. Secondly, a new approach of integrated simulation method, utilizing Moldflow and ANSYS software, was developed to estimate the anisotropic deformation of a carbon fibre filled PEEK-made impeller when it is running at high-speed. The aggregated results are a good baseline as it is comparable with lab results. Finally, the analysis and study of alternative bearing preload design demonstrated that the integrated bearing assembly enhanced the reliability for high-speed motor over the spring preload bearing assembly. ii
