Fractional-slot windings is widely used in synchronous machine due to give us more flexibility on selection of the number of slot at design stage. It is also known that fractional-slot windings produces additional harmonics compare to integral-slot windings. These harmonics may cause increasing of stray losses and stator core vibration This paper describes the result of space flux harmonics caused by fractional-slot windings and propose novel interspersed windings that reduces the even order and/or fractional number space flux harmonic components. The advantage of proposed winding was confirmed by using numerical analysis and experiment using model winding machine.

The authors have studied the saturation characteristic of equivalent circuit of cylindrical synchronous machine. Using the measured data, the authors have studied the effect on the saturation characteristic of equivalent circuits by the finite element method (FEM) and the electromagnetic transients program (ATP-EMTP).
