The design of high-speed machines requires extensive multidisciplinary approach to achieve a high-performance machine. The design process is highly iterative, and analytical methods can accelerate it with faster design iterations at low computational efficiency to find the optimum parameters at conceptual stage. In this study, an analytical design method for obtaining rotor mechanical limits is developed for squirrel-cage slitted high-speed induction machine rotors. In high-speed electric machines, the design is made specifically to meet the application requirements and the objective is to reach a high efficiency. This means that the design needs to be made often from the scratch and existing designs can rarely be used as a starting point. The method developed in this study enables rapid design iterations, especially considering the mechanical limits in the conceptual and layout design phase. The proposed analytical design method is validated with three different case studies.
