    • The present invention relates to a method for the sensorless electric measurement of the position of a rotor of a permanently excited synchronous machine that is fed by a converter, by means of measuring signals which are sent to an evaluation device that calculates the electric position of the rotor from the angular dependence of the current space vector at an impressed stator flux pattern, wherein the distribution of absolute values of the differential current space vector varies in approximation in sinusoidal manner with twice the value of the electric rotor position angle sought. The method of the invention which can be used in particular in stationary or blocked machines is characterized in that the distribution of absolute values is produced from respectively two successive measurements for an almost inversed magnetization, in such a way that the superposition of the impressed stator flux and permanently excited rotor flux enables, due to saturation, a distribution of absolute values of the current space vector with two different maximum values, from which the electric rotor position angle sought is determined directly and unambiguously over 360°.
    • 本发明涉及一种通过测量信号进行无转换电测量永久激励的同步电机的转子位置的方法,所述测量信号被发送到评估装置,所述评估装置计算电动位置 转子从当前空间矢量在外加的定子通量图中的角度依赖性,其中差分电流空间矢量的绝对值的分布以正弦曲线方式近似变化,是所寻求的电动转子位置角度的两倍。 特别是在静止或封闭式机器中可以使用的本发明的方法的特征在于绝对值的分布分别由几乎反转的磁化的两个连续测量产生,使得施加的定子磁通的叠加 并且永久激励的转子磁通能够由于饱和而使得具有两个不同最大值的当前空间矢量的绝对值的分布,从而从所述最大值寻求的电转子位置角度被直接和明确地确定在360°以上。
