一、序言 把磁力轴承用作高速旋转机械轴承的研究,数年来一直在进行,至今尚未达到实用阶段,原因是承载能力低,结构庞大和稳定性差等。由于电磁吸力正比于匝数和激磁电流乘积的平方,靠利用电磁吸力(或永久磁铁斥力)来增加承载能力,它受到铜钱阻抗,绝缘 First, the preamble The use of magnetic bearings as high-speed rotating mechanical bearings has been in progress for several years and has not yet reached the practical stage because of its low carrying capacity, large structure and poor stability. Since the electromagnetic force is proportional to the square of the product of the number of turns and the magnetizing current, it is increased by the use of electromagnetic force (or permanent magnet repulsion)
