摘　　要：基于高速磁浮直线电机的基本结构以及悬浮电磁铁的悬浮、推进和发电基本原理,该文建立了非晶合金常导型高速磁浮直线电机的电磁场有限元仿真计算模型,在相同的激磁电源下,分别计算了无取向硅钢和非晶合金的悬浮电磁铁所受的电磁力。为进一步探究非晶合金在降低高速磁浮直线电机铁芯损耗方面的优势,该文在悬浮电磁铁悬浮电磁力保持恒定的基础上,针对电机低速和额定速度两种不同运行工况,分别计算了无取向硅钢和非晶合金长定子的铁芯损耗。结果表明,无论是在低速还是额定速度下,相比于无取向硅钢,基于非晶合金的直线电机长定子铁芯损耗要小得多。该文为非晶合金材料代替硅钢作为高速磁浮直线电机的导磁材料提供了一定理论支撑。Based on the basic structure of high-speed maglev linear motor and the basic principles of suspension, propulsion and power generation of suspension electromagnet, this paper establishes the finite element simulation model of electromagnetic field of constant conductivity high-speed maglev linear motor, and calculates the electromagnetic force of non-oriented silicon steel and amorphous alloy suspension electromagnet under the same excitation power supply. In order to further explore the advantages of amorphous alloy in reducing the core loss of high-speed maglev linear motor, based on the constant suspension electromagnetic force of suspension electromagnet, the core losses of non-oriented silicon steel and amorphous alloy long stator are calculated respectively under two different operating conditions of low speed and rated speed. The results show that the loss of long stator core of linear motor based on amorphous alloy is much smaller than that of non-oriented silicon steel at both low speed and rated speed. It provides theoretical support for amorphous alloy material to replace silicon steel as the magnetic conducting material of high-speed maglev linear motor.
