摘要 时栅位移传感器以其显著特色在精密测量领域得到广泛的应用。时栅位移传感器结构与电机有着"孪生"关系,将其植入到异步电机的原有结构中,可获取转子位置和速度信息。利用三相自耦变压器的"电磁感应"耦合和"电"的直接联系的特点,解决时栅激励信号在异步电机中的加载问题。理论分析和仿真试验证实了方案的可行性。 The time grating displacement sensor has been widely applied in precision measurements because of its remarkable features. As the structure of time grating displacement sensor has“twin” relation with motor, it can be transplanted into original structure of induction motor, to get the position and speed of the rotor. The three phase autotransformers not only features “electromagnetic induction” coupling, but also features “electric” direct connection, this can be used to load the excitation signal of time grating into induction motor. Through theoretical analysis, simulation and test, the feasibility of the scheme is verified.
