Design of a High-speed Solid-rotor Asynchronous Generator for an Expansion Turbine
Original language description
In this paper, an electromagnetic design of a slitted solid-rotor high-speed generator is presented. Recommendations for an analytical preliminary design were summarized. The design was further optimized using 2-D finite element method. The power of the machine is 6.15 kW at 150 000 rpm and 2% slip. An efficiency of 90% was reached, despite of high eddy losses in the machine rotor. Our design may prove to be a cost-effective alternative to the permanent magnet synchronous machine in the cryogenics application after the thermal and mechanical analysis.
