On the Possibility of Fractional-Slot Concentrated-Winding Permanent Magnet Machine for Wind Power Generation

Abstract

In order to obtain the low synchronous speed, fractional slot concentrated winding is adopted in generation system. This paper analyzed the pole/slot combination rule, and studied the electromagnetic design method. By the finite element software, the characteristics is analyzed for this fractional-slot concentrated-winding permanent magnet generator, the result shows that this generator has a good performance, thus yet proves that fractional slot concentrated winding scheme is feasible.
