Abstract

The invention relates to a permeability alloy for an energy-saving motor and a preparing method thereof. The alloy is prepared from the following alloys in atom ratio: (Fe1-x-yCrxMoy)1-a-b-c-d(Co1-zZrz)aBbSicFd, wherein x=0.03-0.04, y=0.15-0.20, z=0.05-0.1, a=0.25-0.3, b=0.03-0.04, c=0.03-0.05 and d=0.01-0.015. The preparation method includes the following steps: (1), preparation of alloy; (2), preparation of an iron core. The permeability alloy prepared through adopting the method provided by the invention improves the hardness and high temperature resistance of the alloy as a ferro-cobalt material is adopted as a base material and the base material is doped with chromium and molybdenum, improves the soft magnetic properties and value of saturated magnetization due to the doped Zr and Si, and improves the internal resistance of the alloy due to the doped non-metal elements such as F and B, and therefore, the iron core used in an energy-saving motor has excellent magnetic property, lower energy loss and longer service life.

Description

Technical field [0001] The invention relates to a magnetic conductive alloy material for energy-saving motors and a preparation method thereof. Background technique [0002] With the acceleration of industrialization, energy issues have become the focus of contemporary society, and the study of energy-saving materials has become an important aspect of materials research. As one of the important basic components of various types of machinery, the efficiency of the motor has a significant impact on energy conservation and even the sustainable development of the economy. [0003] Traditional AC / DC generators and motors usually use silicon steel sheets as stator cores. The silicon steel sheets have low resistivity and permeability, and form a large magnetic field eddy current, resulting in large iron losses, especially in high-frequency motors. The medium iron loss is larger, which leads to the reduction of the motor performance and the shortened life of the motor due to the hi...
