由于旋转变压器的输出电压与转速无关,且无电刷和滑环,故适用于可控硅调速的同步电动机的励磁系统.利用电路分析和磁路分析的方法,分析了旋转变压器的结构特点,推导出当定子铁心和转子铁心表面对轴心的夹角满足一定的条件,即可保证旋转变压器旋转时的磁阻不变;当气隙比k=2时,三相电压对称.

Since the output voltage of the resolver is independent of the speed and there are no brushes and slip rings, it is suitable for the excitation system of synchronous motors with thyristor speed regulation. Using the methods of circuit analysis and magnetic circuit analysis, the structural characteristics of the resolver are analyzed, and it is derived that when the angle between the stator core and the rotor core surface to the shaft core meets certain conditions, the magnetic resistance of the resolver can be guaranteed to remain unchanged when rotating. When the air gap ratio k=2, the three-phase voltage is symmetrical.
