摘要： Embodiments of this application provide an annular silicon steel sheet, a circular wire motor assembly, a circular wire motor, and a powertrain. The annular silicon steel sheet includes a plurality of open slots, each open slot penetrates the silicon steel sheet in an axial direction of the silicon steel sheet, and a projection of each open slot in the axial direction of the silicon steel sheet includes a first curve segment, a second curve segment, and a third curve segment. The first curve segment and the third curve segment are oppositely arranged in a circumferential direction of the silicon steel sheet, a bending direction of the first curve segment is away from a bending direction of the third curve segment, and a bending direction of the second curve segment is away from an opening of the open slot. The open slot in the annular silicon steel sheet is funnel-shaped, so that a winding slot in the circular wire motor assembly that is formed after a plurality of annular silicon steel sheets are adjacently arranged is funnel-shaped, thereby improving a slot fill factor of the circular wire motor, and further improving performance of the circular wire motor and the powertrain.

摘要： A stator mechanism for a magnetic levitation motor and a stator coil. The stator mechanism includes a stator coil and a stator core. The stator core includes a stator yoke and at least one pair of stator teeth (31). Each of the stator teeth (31) includes a vertical section (311) contacted with the stator yoke and a transverse section (312) at a predetermined angle with the vertical section (311). The stator coil includes an insulating framework (1) and a coil (4). The insulating framework (1) includes an insulating body (11) disposed on an outer surface of the vertical section (311). The insulating body (11) has a first end and a second end opposite to each other in a first extending direction. The first end is provided with a first baffle (12), and the second end is provided with a second baffle (17). The insulating body (11) has a first main surface (111) and a second main surface (112) opposite to each other. The second main surface (112) is a cambered surface protruding outwards away from the first main surface (111). The coil (4) is transversely wound on the first main surface (111) and the second main surface (112) and tightly attached thereto. When a cross-section of the wound coils is of specific shape, coils can be stacked to a maximum density in a limited space.
