Design of High-Speed, Direct-Connected, Permanent-Magnet Motors and Generators for the Petrochemical Industry

This paper re-examines some of the usual assumptions in deploying synchronous machines in multi-megawatt, high-speed applications. A viable design is presented with a focus on rotor capability and cooling system performance that can operate at common gas turbine speeds and power ratings. The models used in the analysis are validated with a similar topology machine, albeit a higher speed and lower power than the proposed design.
