摘    要:三浮陀螺仪输出轴采用有源磁悬浮,系统工作在分时控制模式下,控制变量为总周期和周期内加力占空比.加力电源类型的选取以及加力电压幅值的确定对电磁力的大小、磁悬浮的功耗有很大影响,进而影响陀螺温度场分布和陀螺精度.在研究了磁悬浮元件电磁特性之后,给出了确定加力电源的基于磁路分析的Flux电磁仿真法.分析给出直流、正弦和方波这三种电源的加力幅值范围为1.7V~ 2V,并结合试验确定1.8V的方波电压加力为最佳方案.实验表明采用该方法分析加力电压是有效的,同时节省了大量实验探索的时间.

关 键 词:三浮陀螺仪  有源磁悬浮  电磁仿真  最佳加力电压

Abstract:Three-floated gyroscope output shaft with active magnetic bearing system works under the sub-time control mode which parameter is the strength time. The selection of strength power will affect the amplitude and power consumption, and then affect the temperature distribution and precision of gyroscope. Flux electromagnetic simulation, a useful method based on magnetic circuit, is given after studied the electromagnetic properties of magnetic levitation element. Analysis gives that DC, SW and AC three kinds energizing power amplitude range, and 1.8V square wave force is the best option. Experimental results show that this method analysis energizing power is effective, while saving a lot of experiments to explore time
Keywords:three-floated gyroscope  active magnetic bearing  ( AMB )  electromagnetic simulation  best afterburner power
