Problems solved by technology

[0005] (1) In the manufacturing process, after punching and punching, it is easy to cause deformation and scrapping of the punching sheet during the process of deburring, transportation, heat treatment of magnetic properties, lamination (glue spraying or welding), etc.
[0006] (2) Dimensional accuracy is not easy to control due to the stacking of punching sheets
[0007] (3) Embedding can only be done manually, with low efficiency and unstable process quality

Embodiment Construction

[0031] In order to make the content of the present invention clearer and easier to understand, the content of the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0032] The invention aims to realize the direct winding of the winding coils on the magnetic poles by designing a brand-new assembled structure of the stator iron core of the motor, which can realize mechanized production and improve production efficiency.

[0033] Figure 4 A schematic diagram of the overall structure of the stator core according to the preferred embodiment of the present invention is shown schematically.

[0034] like Figure 4 As shown, the stator core according to the preferred embodiment of the present invention includes: a slot wedge inner cylinder 3 (such as Figure 5 shown), pole 4 (as Image 6 shown) and barrel yoke 5 (such as Figure 7 shown).

[0035] Wherein, the inner cylinder 3 of the slot wedge is made of ins...

Abstract

The present invention provides a stator core and a manufacturing method thereof. The stator core of the invention comprises a slot wedge inner cylinder, a magnetic pole and a tubular magnetic yoke. The slot wedge inner cylinder is made of an insulating material, and a clamping slot for fixing and supporting the magnetic pole is formed at the periphery of the slot wedge inner cylinder. The magneticpole is embedded into the clamping slot at the periphery of the slot wedge inner cylinder to form an insert, and the insert formed by the magnetic pole and the slot wedge inner cylinder is inserted into the tubular magnetic yoke.

Description

technical field [0001] The invention relates to a stator core and a manufacturing method thereof. Background technique [0002] At present, all stator cores of motors are formed by lamination of punched sheets. The motor winding adopts the method of first winding and then manually inserting into the groove. Use slot wedges to seal the slots. The advantage of this structure is that the iron core is integrated, which is conducive to exerting the maximum performance of the material. The disadvantage is that the manufacturing process of winding and embedding is complicated, which is not conducive to the realization of industrialized automatic production line operations. [0003] For example, for the stator core of a four-pole four-slot motor, the existing four-pole four-slot motor stator core has a stamped laminated core and slot wedge insulation structure such as figure 1 As shown, it consists of the following two parts: four slot wedge insulation 1 made of insulating mater...
