  • Electric motor rotor including end ring restrainer
    Patent number: 12567787
    Abstract: An induction motor rotor includes a magnetic metal core; and an electrically conductive metal contiguous with the magnetic metal core. The electrically conductive metal includes rotor bars extending along the magnetic metal core and end segments formed onto opposite ends of the rotor bars. Each of the end segments includes a base section extending a first axial distance from the magnetic metal core and a protrusion extending a second axial distance from the magnetic metal core. The second axial distance is greater than the first axial distance. The induction motor rotor also includes a metal ring positioned on an outer circumferential surface of each of the end segments to prevent the end segments from separating from the rotor bars.

  • PERMANENT MAGNET MACHINE INCLUDING FERROMAGNETIC COMPONENTS FOR EXTERNAL FIELD WEAKENING AND METHOD OF CONSTRUCTING
    Publication number: 20190068037
    Abstract: The permanent magnet machine includes a stator, a rotor inside the stator and a ferromagnetic component fixed axially movably to the rotor. The ferromagnetic component is configured for actuating axially toward the rotor to weaken a magnetic field of the rotor. The method of constructing a permanent magnet machine includes providing a stator and a rotor inside the stator; and axially movably fixing a ferromagnetic component to the rotor such that the ferromagnetic component is configured for actuating axially toward the rotor to weaken a magnetic field of the rotor.
