Analytical modeling of a permanent-magnet synchronous machine in a flywheel

Modelling and optimization of a permanent-magnet machine in a flywheel

This thesis describes the derivation of an analytical model for the design and optimization of a permanent-magnet machine for use in an energy storage flywheel. A prototype of this flywheel is to be used as the peak-power unit in a hybrid electric city bus. The thesis starts by showing the feasibility of using a flywheel energy storage system...
