  • Patent number: 8729767
    Abstract: An electric machine (1), particularly used as an electric motor, has a rotor (2) comprising a plurality of disks (4). A disk (4) of the rotor (2) is divided in a circumferential direction (5) into a plurality of disk sectors (6, 7, 8) between which magnetic pockets (9, 10) are designed. Furthermore, the disk (4) has an inner fastening collar (15) and connecting members (20, 23, 24) connecting the disk sectors (6, 7, 8) to the fastening collar (15). Such a connecting member (20) comprises a main web (21), a side arm (30) branching off the main rib (21) in the circumferential direction (5), and a side arm (31) branching off the main web (21) opposite to the circumferential direction (5). High mechanical stability of the disk (4) can thus be ensured, wherein magnetic flow losses are reduced.

  • Patent number: 8434584
    Abstract: The invention relates to an electric machine (1) comprising: —a rotor (4) having 14 rotor poles (8) which is arranged rotatably about a central axis and—a stator (2) having 12 stator teeth (3) which project in a radial direction relative to the central axis from the stator (2) in the direction of the rotor (4), characterized in that each of the stator teeth (3) is surrounded by a stator coil (9) which surrounds only one of the stator teeth.
