DESIGN OF HIGH-SPEED, DIRECT-CONNECTED, PERMANENT-MAGNET MOTORS AND GENERATORS FOR THE PETROCHEMICAL INDUSTRY

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