摘　　要：本文提出一种新方法制作非晶电机定子铁芯。将非晶Fe80Si9B11(Metglas2605SA1)合金带材380℃热处理100min,放入环氧树脂中浸泡1.2h,,在干燥箱中80℃保温2h固化,并切割成定子铁芯;非晶铁芯饱和磁感可达1.36T,在400Hz和1T下的损耗为2.36W/kg,相对磁导率最大值约10000(50Hz),远优于硅钢35DW310最大磁导率值4600(50Hz),且磁导率随着频率变化基本恒定;将非晶和硅钢铁芯装配成5kW电机,非晶铁芯定子相对硅钢装配的电机效率提升了4.6%,输出转矩增加0.18 N.m,测试非晶合金定子电机的反电动势为142V。采用Infolytica软件仿真计算了两种材料作为定子的电机机械特性,电机效率和反电动势计算值与测试值基本一致,非晶合金比硅钢材料定子齿部的磁滞损耗低10倍左右,非晶材料铁损低是电机效率提高的主要原因。A novel method was introduced to make motor stator core using amorphous alloy ribbon. The a- morphous Fes0Si9B11 （Metglas2605SA1）alloy was prepared as motor stator core, which was soaked into resin for 1.2 h and hardened in drying oven at 80~C for 2h after heat treatment at 380C for 100rain. The saturation magnetic influx density was 1.36T. Iron loss was examined 2.36W/kg when magnetic influx density was 1T and frequency 400Hz. The magnetic permeability keep constant with variety of frequencies and the maximum of magnetic permeability reach 10000 （50Hz）, which was far better than 4600 （50Hz） of silicon steel 35DW310. Amorphous stator was equipped into 5 kW motor which the efficiency of amor- phous alloy stator was improved about 4.6% than silicon steel stator and output torque was improved 0. 18N m. Experimental result of amorphous motor back EMF is 142V. The performance of two alloy sta- tors equipped into 5kW was simulated by Infolytica software. The calculated results of efficiency and back EMF were consistent with experimentation. Low iron loss leadingly caused the efficiency of motor increas- ing that hysteresis loss of amorphous stator was lower 10 times than silicon steel.
