Suitable applications for such machines are low-power vacuum pumps, compressors and chillers. This paper describes a systematic design methodology for a HS PMSM using two case studies. The design process for such highspeed machines is multidisciplinary and highly iterative due to the complex interaction of the many design variables involved. Consequently, no single optimum solution exists and multiple possible solutions can meet the customer requirements. Practical solutions should be within acceptable thermal limits, energyefficient and rigid enough to withstand the forces exerted during operation. The proposed design flow is divided into steps that are presented in the paper in the form of a flow chart with emphasis on mechanical aspects. Each step represents a task for a thermal, mechanical or electric engineer. The features of each step and the prerequisites for moving to the next step are discussed. The described methodology was implemented in the design of two HS PMSMs. The output performance results of the design flow are compared with measured results of the prototypes. The design process described in this paper provides a straightforward procedure for the multidisciplinary design of high-speed permanent magnet electrical machines.

The influence of the main geometric parameters on the loss distribution is studied. Stator core and winding losses as well as rotor sleeve and permanent magnet (PM) losses are evaluated. The effect of the magnetic wedges on the loss distribution is examined. The machine working temperature and related PM demagnetization risks at the rated working point are presented for two-and threephase short-circuits. The total losses of the designed PMSM are evaluated and a minimum total loss value is obtained.

Designing electrical machines necessarily involves several fields of physics, such as electromagnetics, thermics, mechanics, and acoustics. Magnetic, electrical, electronic, and thermal parts are represented by LMs, whereas vibro-acoustic and mechanical parts are represented by analytical models. The aim of this study is to build a design model of a PMSM for traction applications. Each model is parameterized to optimize the machine. The method of taking into account saturation and movement is described. These fast, LMs make it possible to couple the software used with optimization tools. Simulation results are presented and compared with the finite-element method and the experiments performed.
