Fractional Slot

Star-connected and delta-connected circuits of fractional slot concentrated winding in permanent magnets synchronous machines (SMPM) are described in the paper. Advantages and drawbacks of these winding circuit types are shown. Investigation results on the characteristics degradation in the machines with fractional slot concentrated windings owing to delta-connected circuit are presented.

Abstract The electromagnetic noise generated by the Maxwell radial pressure is a well-known consequence. In this paper, we present an analytical tool that allows air gap spatio-temporal pressures to be obtained from the radial flux density created by surface permanent magnet synchronous machines with concentrated winding (SPMSM). This tool based on winding function, a global air-gap permeance analytical model and total magnetomotive force product, determines the analytical air-gap spatio temporal and spectral radial pressure.We will see step-by-step their impacts in generating noise process. Also two predictive methods will be presented to determine the origin of the lows radial pressure orders noise sources. The interest lies in keeping results very quickly and appropriate in order to identify the low order electromagnetic noise origin. Then through an inverse approach using an iterative loop a new winding function is proposed in order to minimize radial force low order previously identified and chosen.
