Problems solved by technology

[0003] In practice, the slot fullness of the winding of the stator block is limited by the winding machine, the winding sequence and the wire diameter. Usually, in order to facilitate the winding of the winding machine, the winding parts on both sides of the winding slot are generally along the slot The center line is arranged symmetrically, and the winding machine winds the wires layer by layer to avoid jumping wires, which leaves a lot of space in the winding groove. In this way, when a plurality of such stator blocks are connected to form a stator, such a Du

Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] refer to figure 1 and figure 2 In the structure shown, the stator can be formed by a plurality of stator block units provided by the present invention. As shown in the figure, the stator block unit 9 includes a first stator block 1 and a second stator block 2 connected along the circumferential direction, and the first stator block 1 and the second stator block 2 can be After the respective coil windings are wound, they are connected to each other to form the stator block unit 9, wherein, in the radial direction of the stator block unit, the outer surface of the first coil winding 3 of the first stator block 1 includes The first straight side 4 at the...

Abstract

The invention relates to the technical field of motors, and discloses a stator block unit, a stator and a motor. The stator block unit comprises a first stator block and a second stator block, whereina first coil winding comprises a first straight edge and a first inclined edge; a second coil winding comprises a second inclined edge and a second straight edge; the first straight edge and the second inclined edge are spaced apart in parallel and the first inclined edge and the second straight edge are space apart in parallel. Between the first stator block and the second stator block, the shapes of the first coil winding and the second coil winding shape are complementary so that the spacing between the two is small, the spacing between the first inclined edge and the adjacent second inclined edge and the spacing between the first inclined edge and the adjacent second straight edge can be small, meaning that the coil winding can be fully wound in the respective winding slot, the surplus space of the winding groove between the first stator block and the second stator block is avoided, so that the groove full rate of the stator is obviously improved, the power density of the motor isimproved, and the volume and the cost of the motor are reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator block unit, a stator and a motor. Background technique [0002] At present, the stator includes a stator core and a stator winding wound on the stator core, and the stator winding is basically formed by winding a winding wire on the stator core by a winding machine. In order to facilitate the winding of the winding machine, the stator is divided into multiple stator blocks, so that the winding machine can wind the wires in the winding slots on each stator block, and then connect the stator blocks circumferentially to Form a monolithic stator. [0003] In practice, the slot fullness of the winding of the stator block is limited by the winding machine, the winding sequence and the wire diameter. Usually, in order to facilitate the winding of the winding machine, the winding parts on both sides of the winding slot are generally along the slot The center line is arranged sy...
