技术领域technical field
本发明涉及单元化径向磁场非晶合金定子的定型模具与成型方法，具体的，是根据非晶带材的特性，制作定型模具，并制造非晶合金定子铁芯，属于电机学领域。The invention relates to a shaping mold and a forming method of a unitized radial magnetic field amorphous alloy stator. Specifically, the shaping mold is made according to the characteristics of the amorphous strip, and the amorphous alloy stator core is manufactured, which belongs to the field of electrical engineering.
背景技术Background technique
非晶合金与硅钢片材料相比，其铁芯损耗极低，高频时更加明显，因此在制造高效、高速、高频、结构紧凑的电机方面，非晶合金有很大优势。但与此同时，非晶合金硬度极高，高温下易“重结晶”，使其软磁特性受到破坏，所以传统的定子铁芯加工工艺并不适合于非晶合金材料。因此，非晶合金电机设计需解决的问题主要为非晶合金定子的结构设计、尺寸设计、定子的加工工艺。近年来，国内外专业技术人员及学者提出了多种非晶合金电机定子的加工方法。中国专利CN101286676B提出了一种高速径向电机非晶合金定子制备方法。其主要缺点是：采用传统的轴向叠片方式制备，铁芯外观尺寸受非晶带材宽度限制，切割加工困难，成本高，材料浪费多。中国专利CN101800456A提出了径向磁场电机非晶合金定子的模块化制作方法，解决了非晶定子铁芯受非晶带材宽度限制的问题，使非晶合金定子适用于直径较大的电机，缺点是：加工方式没有根本上的改进，工艺过程复杂且用时较长，成本高，材料浪费严重。中国专利CN101908796A提出了以常规非晶合金粉末为原料的非晶合金定子制备方法。该方法制造简单，产品稳定性好，缺点是：非晶粉末与粘合剂混合，混合后物质降低了非晶材料本身的软磁特性，磁导率下降，浪费了非晶材料良好的导磁性能。中国专利CN102545415A提出一种非晶合金径向电机，其定子铁芯包含n×Q个U型非晶态合金铁芯。其所提出的卷绕加工方法很难加工出过于锐利的外形，且没有考虑到定子铁芯设计时极靴、极数、齿数、槽型对电机性能和损耗的影响，适用范围和实用性有限。Compared with silicon steel sheet materials, amorphous alloys have extremely low core loss, which is more obvious at high frequencies. Therefore, amorphous alloys have great advantages in manufacturing high-efficiency, high-speed, high-frequency, and compact motors. But at the same time, the hardness of amorphous alloy is extremely high, and it is easy to "recrystallize" at high temperature, which destroys its soft magnetic properties. Therefore, the traditional stator core processing technology is not suitable for amorphous alloy materials. Therefore, the problems to be solved in the design of amorphous alloy motors are mainly the structural design, size design and processing technology of the amorphous alloy stator. In recent years, professional technicians and scholars at home and abroad have proposed a variety of processing methods for amorphous alloy motor stators. Chinese patent CN101286676B proposes a preparation method for an amorphous alloy stator of a high-speed radial motor. Its main disadvantages are: it is prepared by the traditional axial lamination method, the appearance size of the iron core is limited by the width of the amorphous strip, the cutting process is difficult, the cost is high, and there is a lot of material waste. Chinese patent CN101800456A proposes a modular manufacturing method for radial field motor amorphous alloy stator, which solves the problem that the amorphous stator core is limited by the width of the amorphous strip, making the amorphous alloy stator suitable for motors with larger diameters. Yes: There is no fundamental improvement in the processing method, the process is complicated and takes a long time, the cost is high, and the waste of materials is serious. Chinese patent CN101908796A proposes a preparation method of an amorphous alloy stator using conventional amorphous alloy powder as a raw material. This method is simple to manufacture and has good product stability. The disadvantages are: the amorphous powder is mixed with the binder, and the mixed substance reduces the soft magnetic properties of the amorphous material itself, and the magnetic permeability decreases, wasting the good magnetic permeability of the amorphous material. can. Chinese patent CN102545415A proposes an amorphous alloy radial motor, the stator core of which includes n×Q U-shaped amorphous alloy cores. The winding processing method proposed by it is difficult to process an overly sharp shape, and does not take into account the influence of pole shoes, number of poles, number of teeth, and groove shape on the performance and loss of the motor when designing the stator core, so the scope of application and practicability are limited. .
