摘　　要：针对电机与控制系统中,对电机转子位置和电机转速进行检测,从而实现电机高精确度控制的问题,结合电磁场理论设计了一种新型的磁阻式旋转变压器.利用转子磁极的凸极效应,使励磁绕组和输出绕组之间的互感随转子的位置而变化,从而在输出绕组中感应出具有转子位置信息的电动势.对旋转变压器定转子结构、励磁绕组与输出绕组的绕线方式、定转子参数进行优化设计.分析结果表明,这种旋转变压器极对数可任意选取,其精确度可以满足永磁同步电机矢量变换的要求.适用于电机一体化系统.For the problem to test the rotor position and speed in order to realize the high precision control in the motor and drive system, a new kind of variable reluctance resolver has been brought forward according to the electromagnetic field theory. The electromotive force with rotor position information could be induced from the output winding by using the salient pole effect of rotor magnetic pole which could make the mutual inductance between the exciting winding and output winding vary with the rotor position change. The structure of stator and rotor, the wind- ing way of excitation winding and output winding, the parameter optimization of stator and rotor were also dis- cussed. Analysis results show that the number of pole-pairs can change freely and its precision can satisfy the vector transformation requirement of permanent magnet synchronous motor. It is applicable to motor integration system.
