摘要
针对高温高压等恶劣环境下角度测量的需求,研究了一种可以适应恶劣环境的定转子隔离型磁阻式多极旋转变压器,该型隔离型磁阻式多极旋转变压器的定转子间安装了导磁不锈钢屏蔽壳。针对该型隔离型磁阻式多极旋转变压器建立了含有屏蔽壳的磁阻式多极旋变磁路模型,给出了隔离型磁阻式多极旋转变压器的设计依据,对屏蔽壳分走主磁通的问题进行了解析及有限元仿真分析。分析了隔离型磁阻式多极旋转变压器输出信号异常现象,设计了偏置及幅值异常补偿方法。通过仿真分析,结果表明研究的隔离型磁阻式多极旋转变压器能够较明显的抑制异常信号带来的位置解算波动。
In order to meet the demand of angle measurement in high temperature and high pressure severe environment,a stator and rotor isolated magnetoresistive multipolar resolver which can be used in harsh environment is studied.A magnetic conducting stainless steel shielding shell is installed between the stator and rotor of such isolated magnetoresistive multipolar resolver.For this type of isolated magnetoresistive multipolar resolver,the magnetic circuit model of the magnetoresistive multipolar resolver with shielding shell is established,the design basis of such multipolar resolver is given,and the problem of the shielding shell taking away the main magnetic flux is analyzed and simulated by finite element method.The abnormal phenomenon of output signal of isolated magnetoresistive multipolar resolver is analyzed,and the compensation methods of bias and amplitude anomaly are designed.The results of simulation analysis show that the isolated magnetoresistive multipolar resolver can obviously suppress the fluctuation of position solution caused by abnormal signals.
