This paper presents design of an ultra-high-speed generator, propelled by a helium ex- pansion turbine. The power output of the presented generator is 5 kW at 160 000 rpm. Very high efficiency, over 95%, was achieved thanks to the use of permanent magnet synchronous machine type and proper material selection. Special care was taken during design of the machine rotor to meet both mechanical and electromagnetic requirements. Only high-strength materials can withstand the load. Stator sheets have to be very thin, to suppress the skin effect and eddy current losses, especially with the 4 pole configuration. It was shown that the design process for standard, low-speed machines can be used with the awareness of it’s limitations. Weak points of the design, which should be further investigated, were pointed out.
