    摘要： A rotor includes a first rotor core, a second rotor core, a permanent magnet and a resin layer. The first rotor core includes a first core base and first claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the first core base. The second rotor core includes a second core base and second claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the second core base. The first rotor core and the second rotor core are combined with each other so that the first and second core bases are opposed to each other and the first and second claw-shaped magnetic poles are alternately arranged in the circumferential direction of the rotor. The permanent magnet includes at least a main field magnet. The main field magnet is located between the first and second core bases in the axial direction, and is magnetized in the axial direction. The main field magnet causes the first claw-shaped magnetic poles to function as first magnetic poles, and causes the second claw-shaped magnetic poles to function as second magnetic poles. The resin layer covers at least a portion of a surface of the permanent magnet.

    摘要： To provide a rotor member, rotor, and electric motor equipped with the same, which suppress the stress or stretching concentrated on a part of a cylindrical member, thereby enabling to raise the maximum revolution speed, and enabling greater torque to be obtained. In a rotor member fixed by press-fitting to a rotary shaft part of a rotating electrical machine, a thrust member that thrusts a cylindrical member to an outer side in the radial direction against a sleeve part is present between a plurality of magnet segments which are adjacent in the circumferential direction.

    摘要： Some embodiments provided rotor assemblies, comprising: a rotor core barrel comprising a wall extending, and at least two compression bridges each formed in the wall proximate one of the lateral ends and separated by a distance; an array of a plurality of magnets positioned on and spaced along the wall between the compression bridges and about a circumference of the rotor core barrel; and one or more pre-stress wraps wrapped over the plurality of magnets and about the rotor core barrel along at least a portion of a length of the rotor core barrel between the compression bridges, wherein the compression bridges enable radial compression deflection, induced by radial compression of the rotor core barrel by the one or more pre-stress wraps, of the wall of the rotor core barrel at the compression bridges relative to the wall of the rotor core barrel proximate the lateral ends.
