  • Rotor for an electric motor or generator
    Patent number: 10491067
    Abstract: A radial portion of a rotor is rotatably mounted to a stator and a cylindrical portion axially extends over radial teeth formed on the stator. A first surface of the first soft ferromagnetic material element is mounted to an inner surface of the cylindrical portion and a second surface of the first soft ferromagnetic material element has mounted on it a first magnet such that a surface of a pole of the first magnet is oriented substantially non perpendicular to a line from the centre of the rotor to the first magnet. A first surface of a second soft ferromagnetic material element is mounted to the first magnet such that the first magnet is sandwiched between the first and second soft ferromagnetic material elements. A second surface of the second soft ferromagnetic material element is substantially perpendicular to the line from the centre of the rotor to the first magnet.

  • A ROTOR FOR AN ELECTRIC MOTOR OR GENERATOR
    Publication number: 20160344246
    Abstract: A rotor for an electric motor or generator, the rotor comprising a radial portion, a cylindrical portion, a first soft ferromagnetic material element, and a second soft ferromagnetic material element, wherein the radial portion is arranged to be rotatably mounted to a stator and the cylindrical portion is arranged to axially extend over radial teeth formed on the stator when the rotor is rotatably mounted to the stator, wherein a first surface of the first soft ferromagnetic material element is mounted to an inner surface of the cylindrical portion and a second surface of the first soft ferromagnetic material element is arranged to have mounted on it a first magnet such that a surface of a pole of the first magnet is oriented substantially non perpendicular to a line from the centre of the rotor to the first magnet, wherein a first surface of the second soft ferromagnetic material element is arranged to be mounted to the first magnet such that the first magnet is sandwiched between the first soft ferromagneti
