Abstract
A electrical power plant with a gas turbine engine that drives two electric high speed generators connected on the two ends of the engine rotor shaft in a direct drive relation without the need for a gear box. The high speed generators can be of the same or different power rating and connected in series such that the total power output can easily be changed without the need to redesign larger high speed generators. Because the generators use permanent magnets, they can be operated as motors to drive two or more compressors. A turbine can be used to drive two or more high speed generators connected in series. Since the high speed generator/motors have thrust bearings, the thrust bearing in the turbomachine can be eliminated.
