主动磁力轴承功耗研究

Study on the power consumption of the main active magnetic bearings

介绍了一种磁力轴承的功耗分析模型。功耗导致磁力轴承和转子发热,从而对磁力轴承转子的转速和精度提高产生很大的影响。分析结果对磁力轴承结构的改进,减小温度升高具有重要的参考价值。

This paper presents a analytical method to predict rotational losses for laminated rotors of magnetic bearings, These losses can result in the over - heating of magnetic beatings and rotor which can bring a significant influence to improving the speed and precision of the rotor. The analysis results are useful for the improvement of the structure of the magnetic beating and the reduction of temperature rising.
