The development of low-cost, brushless rotating machine systems with high broad band efficiency is critical for the production of effective flywheel modules for electric vehicles. The Charles Stark Draper Laboratory has been developing a variety of brushless machine systems which appear to have the potential for both low cost and high broad band efficiency. The rotating machines utilized in these systems include wound rotor, induction, inductor, permanent magnet, and special purpose machines. The converters considered for use with these machines include D.C. link inverters, phase controlled rectifiers, cycloconverters, and special purpose switching system. This paper will review work recently and/or currently funded at the Draper Laboratory in the flywheel conversion area by NSF, DOT, and NASA. Emphasis will be placed on several unique machine concepts developed at the Draper Laboratory for flywheel application. These include a field modulator inductor motor alternator, an optimum slip induction motor, and a permanent magnet brushless D.C. motor controlle for optimum torque angle. The results of experiments and analytical studies indicated that these approaches result in both overall system simplification and cost reduction as well as increasing broad band efficiency. (DePo)
