本文叙述国营航空空间公司按照欧洲空间局合同为卫星稳定而研制的磁悬浮动量轮和反作用轮的构造特点及其性能参数。文中详细地论述了这些飞轮的各种功能元件及其设计和选择所依据的理论基础。对磁轴承飞轮与一般轴承飞轮做了全面的比较,并认为,不仅从可靠性的观点看,而且从质量和功耗方面考虑,磁轴承也是优良的。 This article describes the structural characteristics and performance parameters of the maglev momentum wheel and the reaction wheel developed by the state-owned aeronautical space corporation for satellite stabilization in accordance with the contract of the European Space Agency. The paper discusses in detail the various functional components of these flywheels and the theoretical basis on which they are designed and selected. The magnetic bearing flywheel and the general bearing flywheel made a comprehensive comparison and believes that not only from the reliability point of view, but also from the quality and power considerations, magnetic bearings are also excellent.
