Abstract :
This paper proposes and implements a new 36/24-pole outer-rotor permanent magnet (PM) hybrid machine for directly coupled wind power generation. The key is to design the machine with hybridization of two excitations (PMs and dc field windings) in the double-layer stator so that it can provide effective flux control, hence realizing constant voltage output over wide ranges of speeds and loads. The machine design is illustrated by finite-element analysis and then verified by experimentation.
