  • Publication number: 20230051972
    Abstract: A motor rotor includes an iron core. A mounting groove is recessed from an end surface of the iron core and extends in a direction from a middle of the iron core to an outer peripheral surface of the iron core. The motor rotor further includes a first magnet and a second magnet embedded in the mounting groove and arranged at an interval along an extension direction of the mounting groove. The first magnet is fixed at a radial outer side of the second magnet. A magnetization direction of each of the first magnet and the second magnet is perpendicular to the extension direction of the mounting groove. A coercive force of the first magnet being greater than a coercive force of the second magnet.

  • Publication number: 20180008937
    Abstract: A composite molecular sieve membrane, preparation method and use thereof are provided in the embodiments. The composite molecular sieve membrane includes a support layer and a molecular sieve membrane layer, wherein the support layer is a high-porosity and porous ceramic which is made of nano- or submicron ceramic powder materials or ceramic material precursors prepared through an electrospinning process. The high-porosity and porous ceramic, is adjustable from 40% to 83%. The composite molecular sieve membrane of the embodiments uses the porous ceramic prepared through an electrospinning process as the support layer, and the support layer has a flat and continuous surface, high porosity, uniform and adjustable pore sizes, low-tortuosity pore channels, and high mechanical strength; the flux of the composite molecular sieve membrane is increased, besides, the seed crystals can attach effectively due to the fibrous pore channels of the support layer, ensuring the adhesion amount of seed crystals.
