  • FRACTIONAL SLOT WINDING CONFIGURATION FOR ELECTRIC MOTORS
    Publication number: 20110012466
    Abstract: Methods and apparatus are provided for stator assembly for use with an electric motor assembly. The stator assembly includes, but is not limited to a stator core that has an inner surface and a plurality of stator slots defined in the inner surface. A fractional slot winding having a plurality of conductors is coupled to the stator core. Each stator slot contains a group of the conductors arranged in a radially adjacent configuration. The groups of conductors in each of the stator slots together form a plurality of concentric rings of conductors. The conductors in each mixed group are arranged such that conductors carrying differing phases of electric current are arranged in a radially alternating configuration.
