Zusammenfassung:An apparatus (17) for detecting the direction of rotation of a magnetic bearing rotor comprises:-comparison means (100) configured to compare a rotational speed of the rotor with a predetermined speed threshold (Se),-first determination means (105) configured to determine a rotational speed gradient of the rotor, and-second determination means (107) configured to determine a rotational speed gradient of the rotor, it is configured to determine the direction of rotation of the rotor as a function of a comparison of the rotational speed of the rotor with a predetermined speed threshold value (Se) and of a value of a determination parameter representative of rotor dynamics. 用于检测磁性轴承转子的旋转方向的设备(17)包括:-比较装置(100),其配置成将转子的旋转速度与预定速度阈值(Se)进行比较,-第一确定装置(105),其配置成确定转子的旋转速度梯度,以及-第二确定装置(107),其配置成根据转子的旋转速度与预定速度阈值(Se)的比较结果和代表转子动力学的确定参数的值来确定转子的旋转方向。
