  • Publication number: 20220209595
    Abstract: A synchronous reluctance motor includes a rotor and a stator surrounding the rotor. The rotator includes a rotatable shaft and magnetic flux barrier layers arranged radially. One of the magnetic flux barrier layers closest to the stator is filled with a conductor, and one of the magnetic flux barrier layers closest to the rotating shaft is a void.

  • Publication number: 20210296948
    Abstract: A rotor includes a rotor core that is made of electromagnetic steel sheets rotating around a central axis and laminated in an axial direction, and that has multiple flux barriers penetrating the electromagnetic steel sheets along the axial direction. At least some of the multiple flux barriers are provided with a first penetrating portion and a second penetrating portion arranged in the radial direction, the first penetrating portion housing a magnet and the second penetrating portion housing a conductive non-magnetic conductor.

  • Publication number: 20210211001
    Abstract: An embodiment of the present invention provides a rotor and a motor having the rotor. By providing a plurality of flux barrier groups and slot groups at intervals in a circumferential direction of the rotor iron core, it is possible to flexibly arrange the numbers of the flux barrier groups and the slot groups so as to meet the requirements for the number of poles of different products. In addition, by flexibly adjusting the quantity ratio between the flux barrier groups and the slot groups and/or the quantity relationship between the flux barriers in the flux barrier group and the slots in the slot group, it is possible to meet the requirements for motor efficiency and starting capacity of different products. Further, since the processing jig of the rotor only requires processing of the structures of the flux barriers and the slots, the manufacturing cost can be reduced.

  • Publication number: 20200412217
    Abstract: Embodiments of the disclosure provide a rotor, a motor, and a driving apparatus. The rotor is defined by laminated electromagnetic steel plates. The electromagnetic steel plate includes a plurality of through hole groups running through the electromagnetic steel plate, and each through hole group includes a plurality of through holes. A central axis of a magnetic pole of the rotor is used as a d axis, and an axis that is 45 degrees from the d axis is used as a q axis, where an outer peripheral surface of the rotor that is between the d axis and the q axis is recessed radially inward relative to an outer peripheral surface of another portion of the rotor, so that the rotor is noncircular when observed in an axial direction.
