磁阻式多极旋变的等值电路和参数

Equivalent Circuit and Parameters of VR Multipolar Resolver

磁阻式旋变的工作是基于气隙磁导变化与输出绕组电压成一定关系的原理.为了获得精确定位精度,准确地进行参数计算是非常重要的,文中介绍其等值电路和参数计算.

The operational principle of VR resolver is based on permeance variation in airgap so that the voltage in output winding vary with the position of rotor is induced. To get high position accuracy it is importance the parameter is well calculated. The. paper describes the equivalent circuit and parameters calculations for the VR resolver.
