Abstract: A rotor of a synchronous reluctance motor may include: a plurality of laminations forming a stack, each lamination including: two parallel surfaces and a perimeter that define the lamination and a direction of stacking the laminations that is perpendicular to the parallel surfaces, the lamination at least partially filled with a magnetically soft electrical conductor and at least one cavity encircled by the conductor and extending from a first to a second surface of the two parallel surfaces, the conductor forming at least one bridge at the perimeter of the lamination from one side of the at least one cavity to another side of the at least one cavity. A value of a magnetic property and a value of a mechanical property of the at least one bridge differs from a value of the magnetic property and a value of the mechanical property of the conductor material.

Abstract: A method for additive manufacturing of an article having a controlled magnetic anisotropy includes: forming a metallic layer of the article using additive manufacturing, the metallic layer having a magnetic anisotropy aligned in a first direction; forming a subsequent metallic layer of the article using additive manufacturing, the subsequent metallic layer having the magnetic anisotropy aligned in a second direction different from the first direction; and repeating the forming of subsequent metallic layers of the article to form at least a portion of the article, each subsequent metallic layer having the magnetic anisotropy aligned in a different direction than a previous metallic layer.

Abstract: A rotating electrical machine of the double stator configuration includes a rotor shaped as a hollow cylinder disposed concentrically between an outer stator and an inner stator. The rotor can include plurality of radially spaced magnet cavities configured to receive permanent magnetic bars. To provide sufficient stiffness and rigidity, the rotor may be made from fiber composite material. To simplify construction, the rotor can be assembled from a plurality of rotor segments radially arranged about an axis line in which the magnet cavities are disposed.

Abstract: A method for molding a magnetic material into a rotor stack, including providing a polymer melt including magnetic compound particles and a polymer binder, providing a rotor including a plurality of cavities, the rotor being arranged in a mold having a mold cavity surface, and providing a gap between the outer periphery of the rotor and the mold cavity surface. The method also includes filling a first volume of the polymer melt into the cavities of the rotor at a first pressure and filling a second volume of the polymer melt into the rotor at one or more second pressures, the one or more second pressures being less than the first pressure and above an ambient pressure.

Abstract: A modular pulley assembly for a continuous belt conveyor can be assembly from a plurality of modular pulley disks that can be axially aligned and abut against each other to provide pulleys of differing lengths per demand. The modular pulley disks can be made from a non-metallic material such as a polymer and can manufactured by a suitable molding process. Making the modular pulley disks from non-metallic materials enables the disks to be formed with structural geometries such that the assembled pulley is structurally more rigid and can better distribute torsional loads and momentum from the belt to the support shaft.

Abstract: A rotor for an electric machine is disclosed, the rotor including a plurality of cavities filled with a magnetic material. In the disclosed rotor, the magnetic material includes Samarium-Iron-Nitrogen (Sm—Fe—N) particles, Manganese-Bismuth (Mn—Bi) particles, and a polymer binder. Performance characteristics of the magnetic material, such as following the rule of mixtures and exhibiting a linear relationship based on volume fraction of the Mn—Bi particles, is also disclosed.
