High-Speed Electric Machine Frame Design Process Using Topology Optimization

Abstract

High-speed electric machines have been developed for decades thanks to their high efficiency and power density. The problem with the development of high speed electrical machines is the long and iterative design process which is usually tailored to each machine. One part of the design process is the design of the frame, for which there has been no systematic process in the past. In this work, a design process was developed in which initial values and a target are used to create frame structures optimized for specific or maximized frequency. The developed design process utilizes topological optimization to generate optimal frame structures for high-speed electrical machines.
