本文在过去几年的研究基础上,从球形气体轴承的特殊情况出发,分析了动压气浮自由转子陀螺仪和框架陀螺之间驱动马达的设计思想和参数选择的不同点,叙述了驱动马达给动压气浮自由转子陀螺仪产生的误差,论述了减小和消除这些误差的方法。同时,文章还引出了驱动马达的设计参数和试验结果。 Based on the research of the past few years and based on the research of the spherical gas bearings, this paper analyzes the difference between the design idea and parameter selection of the driving motor between the air-floating free-rotor gyroscope and the frame gyroscope. The errors of the air-floating free rotor gyroscope are discussed, and the methods to reduce and eliminate these errors are discussed. At the same time, the article also leads to the design parameters and test results of the drive motor.
