摘　　要：介绍了双回转机构在LAMOST光纤定位单元中的应用。双回转机构由中心回转轴和偏心回转轴组成 ,由步进电机通过蜗轮蜗杆机构驱动 ,由消隙机构消除间隙。双回转机构的步进电机控制电路由TDA15 2 1音频集成功率放大器组成平衡桥式功率驱动电路 。The application of the double gyration device on LAMOST fiber positioning unit is introduced. The double gyration device is built up by a center gyration axle and an eccentric gyration axle which are driven by stepping motors with worm gearing. To control stepping motors, the balance bridge power drive circuit is made up by TDA1521 integrated audio power amplifier, the pulse allotter is made up by the parallel ports of computer and latches.
