Embodiment Construction

[0039] Please also refer to Figure 1 to Figure 4 , as shown in the figure, the winding mold of the amorphous alloy stator core includes a base mold for winding and a clamping mold matched with the base mold. The base mold 1 further includes a base 10, and the center of the base is opened There are concentric holes 11, and 1 to N central winding shafts 12 are installed on the base, where N>1, and the central winding shafts are fixed on the base by bolts; the central winding shafts surround the concentric holes and are evenly arranged as a The center of the ring is arranged concentrically with the concentric hole, and there is a gap between two adjacent center winding shafts, so there are also 1 to N gaps; the gap between the outer walls of two adjacent center winding shafts is the outer opening of the gap; The gap between the inner sidewalls of two adjacent central winding shafts is the gap inner opening; the clamping mold further includes an outer clamping mold 2 and an inner...

Abstract

The invention discloses a winding die and a preparation method for an amorphous alloy stator core. The winding die comprises a fundamental die for winding and a clamping die matched with the fundamental die. The fundamental die comprises a base of which the center is provided with a concentric hole. One to N central bobbins are arranged on the base, wherein N is more than 1. The clamping die comprises an outer clamping die and an inner clamping die which are arranged concentrically with the concentric hole. An amorphous alloy belt is subjected to head fixation, two-way winding, closure, molding, impregnation curing and de-molding in the winding die to prepare the amorphous alloy stator core. The amorphous alloy stator core is prepared by adopting a unique winding method rather than a conventional stamping or linear cutting method, so that the preparation method is simple, and raw materials are fully utilized in a preparation process to avoid the waste of the raw materials, decrease the production cost of the amorphous alloy stator core, greatly facilitate the application of the amorphous alloy stator core in the field of motor stator cores and improve the competitiveness of production enterprises.

Description

technical field [0001] The invention relates to a stator core preparation process, in particular to a winding mold for an amorphous alloy stator core. [0002] The invention also relates to a preparation method of the amorphous alloy stator core. Background technique [0003] The stator core is an important part that constitutes the motor magnetic flux circuit and fixes the stator coil. It is composed of stator pieces and various fasteners to form a whole. [0004] The basic requirements of the stator core: [0005] 1) Good magnetic conductivity and low loss. [0006] 2) Good rigidity and strong vibration resistance. [0007] 3) There is a good ventilation effect in the structural layout. [0008] 4) After lamination, the inner diameter and groove size of the iron core should meet the design accuracy requirements. [0009] The Chinese patent has disclosed a utility model patent with the patent number "201120211306.3" and the invention name "a stator iron chip", which in...
