    • Apparatus for detecting possible changes or variations in the dimension of an air gap of a running electric rotary machine during operation thereof. Detector coils are each accommodated within respective slots formed in the stator core of the machine, the coils being geometrically separated from one another at an angular distance corresponding to the distance between poles or its integral multiple. The detector coils are electrically connected in series with each other to produce a voltage for detection. The detector coils are so connected that the fundamental waves of the voltages induced in two detector coils will cancel each other and a synthesized value of higher harmonics induced in both detector coils is picked up as the detection voltage signal. The number of slots of the rotor of the electric rotary machine is predetermined to a limited number in order to get a detection signal of higher quality.
    • 用于检测运行中的电动旋转机器的运行期间气隙的尺寸变化的装置。 检测器线圈各自容纳在形成在机器的定子芯中的相应的槽内,线圈以对应于极间距离或其整数倍的角距离彼此几何地分开。 检测器线圈彼此串联电连接以产生用于检测的电压。 检测器线圈被连接成使得在两个检测器线圈中感应的电压的基波彼此抵消,并且拾取两个检测器线圈中感应的高次谐波的合成值作为检测电压信号。 为了获得更高质量的检测信号,电动旋转机械的转子的槽数被预先确定为有限数量。
