  • Stator for permanent magnet electric motor using soft magnetic composites
    Patent number: 7755244
    Abstract: A stator of an electrical machine operable as a motor or a generator, applicable to a radial-axial type machine. The stator includes a plurality of stator segments disposed circumferentially about an axis. Each segment has a generally wedge shaped core and a winding wound around the core. The winding is bent to have portions that are disposed on multiple planes. The core includes an elongated wedge tip portions aligned parallel to the axis and an outer radial face opposite to the tip portion. The multiple planes include at least one plane substantially normal to the axis and at least one plane tangential to the radial face.
