Structural and thermal design of a dual-rotor constant-frequency, variable-speed generator

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering; and, (S.B.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2003.Includes bibliographical references (p. 31).The mechanical design of a novel generator type is considered. This generator is intended to efficiently, reliably and cheaply convert a variable shaft-speed input into a constant electrical frequency output for application in the field of wind power. A optimization of the electrical characteristics has been performed and used as constraints on the mechanical design. Structural and thermal analyses of the design have been performed, and the design thereby specified to the point that a prototype can be constructed for testing.by Andrew J. Thomas.S.B
