  • Publication number: 20200295626
    Abstract: A motor and stator include first and second laminations arranged adjacently in the axial direction. The laminations include sub-yoke parts and first tooth parts. The sub-yoke parts are spliced through a yoke engaging part to form a substantially annular yoke part. The tooth parts are assembled on an inner edge of the yoke part through a tooth engaging part. A first tooth engaging part and a second tooth engaging part are superposed in the axial direction, the first tooth engaging part being different from the second tooth engaging part. A method of manufacturing a stator for a motor is also disclosed.

  • Publication number: 20200244113
    Abstract: A stator for a motor includes laminations arranged axially adjacently. A first lamination includes sub-yoke parts and tooth parts. The sub-yoke parts are spliced through a first yoke engaging part to form an annular first yoke part. The first tooth parts are assembled on an inner edge of the first yoke part through a first tooth engaging part. The second lamination includes sub-yoke parts and tooth parts. The sub-yoke parts are spliced through a second yoke engaging part to form an annular second yoke part. The second tooth parts are assembled on an inner edge of the second yoke part through a second tooth engaging part. The first and second tooth engaging parts are superposed in the axial direction. A method of manufacturing a stator for a motor is also described.

  • Publication number: 20200235642
    Abstract: A motor rotor may include a body having axially extending first and second magnets embedded into the body, the first magnet and the second magnet being arranged at an angle and spaced apart by an axially extending magnetic shielding component. The first magnet includes a first surface away from a central axis of the rotor body and a second surface facing the central axis. The second magnet includes a third surface away from the central axis and a fourth surface facing the central axis, wherein the first surface and the third surface and extension surfaces thereof define a first area of the body part away from the central axis and a second area of the body part close to the central axis.

  • Publication number: 20200212734
    Abstract: An electric machine operable as a motor or generator includes a stator having a body portion substantially in the shape of a hollow column with an outer wall and an inner wall. The body portion has a plurality of first slots and a plurality of second slots each running through the body portion in a longitudinal direction. The plurality of first slots are distributed in a circumferential direction between the outer wall and the inner wall, and the first slots are circumferentially closed slots. The plurality of second slots are distributed in the circumferential direction between the first slots and the inner wall, and the second slots are circumferentially closed slots and are spaced apart from the first slots.

  • Publication number: 20200169128
    Abstract: A stator core for an electric motor may include a main body part formed by a plurality of stacked electromagnetic steel sheets, the main body part being provided with at least a first through hole extending axially with a first pin located in the first through hole. A first end cover is located at a first end of the main body part and connected to a first pin end of the first pin. A second end cover is located at a second end of the main body part and connected to a second pin end of the first pin. The connections of the first end cover and the second end cover to the first pin generate tensile stresses in the main body part to reduce core losses.
