US Patent 10326326 IPM machine with specialized winding for automotive electric vehicles

Certain aspects relate to designs for an interior permanent magnet (IPM) electrical machine stator having a plurality of continuous windings wound through the stator. Compared to existing designs, the disclosed stator design has an increased number of parallel conductors, an increased number of conductors per slot, increased tooth and slot width and number, and more compacted conductors, resulting in reduction in core losses, reduction in conductor losses, reduced harmonics in flux density, and improved winding reliability.
