    摘要： Provided is a rotor of a motor, capable of suppressing a decrease in the amount of magnetic flux generated from a magnet while reducing the influence of demagnetization. A rotor (10) is provided so as to be rotatable about an axis (C), and includes a permanent magnet (40) and a rotor core (20). The permanent magnet (40) has a demagnetization portion (40a) disposed near the outer peripheral surface of the rotor (10) when viewed along the axis (C). The rotor core (20) forms a magnetic flux barrier (24) which is a hole or cutaway disposed near the demagnetization portion (40a) when viewed along the axis (C). The magnetization direction of the demagnetization portion (40a) is oriented in the circumferential direction of the rotor (10). The rotor (10) has a cylindrical shape with a radius R.

    摘要： The present invention relates to a permanent magnet rotor for an electric machine, comprising: a shaft rotatable about a rotating axis; a plurality of permanent magnets; a rotor core comprising a lamination stack having a plurality of rotor laminations comprising two extremal rotor laminations and a plurality of intermediate rotor laminations arranged in between the two extremal rotor laminations. Further, each rotor lamination of the plurality of rotor laminations comprises a plurality of magnet apertures therein arranged so that to form together a plurality of magnet housings. The plurality of rotor laminations comprises one retaining rotor lamination, which is one of the two extremal rotor laminations, and the plurality of magnet apertures of the one retaining rotor lamination has a dimension different from a dimension of corresponding magnet apertures of remaining rotor laminations of the lamination stack.

    摘要： A rotor structure includes a laminated silicon steel sheet structure, end plates, a shaft and a thermoset plastic key. Each silicon steel sheet includes a shaft hole and at least one sheet matching portion, and the sheet matching portion is connected to the shaft hole. The shaft passes through the shaft holes of the silicon steel sheets and the at least one shaft matching portions aligned with the at least one sheet matching portion to form an axial-direction injection passageway. The end plate includes an injection port connected to the axial-direction injection passageway. The thermoset plastic key is formed in the axial-direction injection passageway formed of the aligned shaft matching portions and sheet matching portion by transfer injection molding. The injection material is filled in magnet slots for securing magnets. A rotor manufacturing process is also provided.

    摘要： A rotor comprises laminations with a plurality of rotor bar slots with an asymmetric arrangement about the rotor. The laminations also have magnet slots equiangularly spaced about the rotor. The magnet slots extend near to the rotor outer diameter and have permanent magnets disposed in the magnet slots creating magnetic poles. The magnet slots may be formed longer than the permanent magnets disposed in the magnets slots and define one or more magnet slot apertures. The permanent magnets define a number of poles and a pole pitch. The rotor bar slots are spaced from adjacent magnet slots by a distance that is at least 4% of the pole pitch. Conductive material is disposed in the rotor bar slots, and in some embodiments, may be disposed in the magnet slot apertures.
