Description

Amorphous motor, method for making the same, and device for implementing the method

technical field

The present invention relates to the technical field of motor preparation, in particular to an amorphous motor, a manufacturing method thereof, and a device for implementing the manufacturing method.

Background technique

Amorphous soft magnetic alloy materials have excellent properties such as high magnetic permeability, low coercivity and low loss, and are known as one of the preferred materials for green energy saving in the future. However, amorphous soft magnetic materials have high hardness, thin thickness, and are prone to brittle cracking. They are not as easy to form as traditional magnetic materials such as silicon steel, permalloy, and ferrite to prepare magnetic cores. Therefore, traditional soft magnetic materials are used to prepare magnetic cores. The traditional process of motor magnetic core is obviously not suitable for the preparation of amorphous motor magnetic core.专利CN202010486517.1，CN201911229905.5，CN201910684542.8，CN201910431204.3，CN201811568519.4，CN201521024265.1，CN201510555750.X，CN201520536486.0，CN201520081441.9，CN201410165524.6，CN201310676351.X根据非晶软磁薄With the characteristics of the strip, the stator or rotor of the amorphous motor is made by the process of coiling and cutting, or wire cutting after punching. Since the thickness of the amorphous thin strip is only one tenth of that of the silicon steel sheet, this kind of coiling or lamination makes amorphous Compared with the traditional silicon steel sheet, the motor process has low efficiency, and the amorphous material is brittle, and the processing difficulty is much greater than that of silicon steel. Therefore, the existing technology is difficult to overcome the production and production of amorphous motor magnetic cores. Low efficiency and high manufacturing cost. The patent CN201220153404.0 uses the die extrusion method to make the magnetic core of the amorphous motor. Although the problems caused by the cutting process are avoided, the problems of brittleness and low filling coefficient are encountered.

The current processing technology of the magnetic core of the amorphous motor has low production efficiency and high cost, and it is difficult to achieve large-scale mass production, and it is impossible to realize the popularization and application of the amorphous motor. The fundamental reason is that the current amorphous motor is limited to the structure of the traditional motor, and the materials for processing the magnetic core are wide amorphous thin strips. Using wide amorphous thin strips to make traditional motor magnetic cores, when encountering thin amorphous thin strips (only one tenth of the thickness of silicon steel sheets), high hardness and easy brittle cracking, it is difficult to process traditional motor magnetic cores like silicon steel sheets. The complex structure of the core. It can be seen that the current amorphous motor preparation technology is limited by two factors, the traditional motor structure and the difficulty of processing wide amorphous strips, and it is difficult to achieve large-scale popularization and application. In order to solve the difficulties encountered in the production of amorphous motors, it is necessary to make breakthroughs from the two aspects of motor structure and amorphous magnetic core processing, and design a new structure of the motor, so that the new structure motor is suitable for the excellent performance of amorphous soft magnetic materials, and at the same time. Avoid the disadvantages of high hardness, brittleness and difficult processing of amorphous materials.

In view of the above reasons, in view of the current difficulties encountered in the manufacture of amorphous motors, the present invention adopts the method of manufacturing the axial driving magnetic core with amorphous thin strips, that is, the magnetic core of the motor is manufactured by using amorphous thin strips instead of amorphous broadband, and the shaft The amorphous motor structure is designed to drive rather than radial drive, which well solves the current difficulties encountered in the production of amorphous motors. The technology of the present invention does not need coiling, nor complicated processes such as punching, laminating, wire cutting, etc., which greatly simplifies the manufacturing process and reduces the difficulty of the process, and not only overcomes the problems of the prior art due to the small thickness, high hardness, and high brittleness of the thin amorphous ribbon. factors, resulting in difficult processing of amorphous magnetic cores, low efficiency and high cost, which significantly improves production efficiency. Moreover, it also realizes full utilization of amorphous materials, and there is no material waste caused by punching, cutting and other processes in the current technology. , there is almost no material waste in the whole production process; more importantly, compared with the traditional structure of the amorphous motor prepared by the current technology, the weight of the same power motor can be reduced by more than 30%, which greatly saves money. The cost can greatly reduce the price. Meanwhile, the magnetic circuit length of the amorphous motor prepared by the invention is only half of that of the traditional motor, so that the hysteresis loss and eddy current loss of the magnetic core of the motor are significantly reduced, and the efficiency of the amorphous motor is obviously improved.
