Description

Technical Field

[0001] The utility model relates to the field of motors, and in particular to a novel flat wire motor stator structure. Background Art

[0002] The stator assembly of a traditional flat wire motor consists of a stator core, insulating material and a hairpin winding, and the winding form is a segmented U-shaped hairpin winding or a continuous waveform winding. Compared with the traditional round wire motor manufacturing process, the hairpin flat wire motor has the following disadvantages: 1. Various special equipment are required, and the investment cost is high. 2. Its insulation and welding consistency requirements are high. 3. The number of turns of the wire diameter is difficult to adjust, and the equipment versatility is poor. 4. There are many processes, high process requirements, and poor maintainability. 5. It is difficult to serialize products and requires top-level design. In order to solve the above problems, a new flat wire motor stator structure that is easy to process and assemble is needed. Utility Model Content

[0003] The utility model aims to provide a novel flat wire motor stator structure with convenient winding, adjustable wire diameter and number of turns, and no need for complex shaping and a large amount of welding after assembly. The specific technical scheme is as follows:

[0004] A novel flat wire motor stator structure, characterized by:

[0005] It includes a core support, a spiral winding and a stator block;

[0006] The core support is an annular structure, the inner circumferential surface of the core support is uniformly provided with slots along the annular direction, the spiral winding is sleeved on the stator block, and each of the slots is connected to the stator block;

[0007] The inner end of the stator block is adapted to the slot structure, and the inner end of the stator block is engaged in the slot.

[0008] In order to better implement the present utility model, it can be further provided that: the spiral winding is a rectangular structure.

[0009] Furthermore, the slot is a T-shaped slot, and the inner end of the stator block is provided with a T-shaped platform adapted to the T-shaped slot structure.

[0010] Furthermore: insulating frames are respectively provided on both sides of the outer end of the stator block, and the spiral winding is located between the insulating frame and the T-shaped stage.

[0011] Furthermore: an insulating layer is provided on the outer surface of the stator block.

[0012] The beneficial effects of the utility model are:

[0013] The overall structure is simple. Due to the block-type installation, the motor production is simpler and more efficient. The winding is first installed on the stator block, and then the block is installed on the core bracket, which is convenient for independent production and assembly. Since the spiral winding uses flat wire winding, the motor has a smaller volume, less material, lower cost, and high slot fill rate and power density under the same power. Compared with the hairpin winding, this winding is simpler to wind, and the later installation is convenient and quick. The motor stator can be completed without a lot of welding, which greatly reduces the production cost and cycle. BRIEF DESCRIPTION OF THE DRAWINGS
