Abstract :
Direct-drive wind energy conversion systems (WECS) are required to operate at low speeds determined by that of the turbine. This paper addresses the problem of adapting a small, standard, readily available PM synchronous machine for direct coupling to a small wind turbine. In particular, it investigates several minor changes to the machine design, which will ensure that rated power can be delivered to its load, whilst operating at the reduced speeds required by a direct-drive WECS.
