摘要： An improved system for monitoring vibration of an electric machine is disclosed. According to one embodiment, sensors are positioned in a plane orthogonal to the motor shaft and each sensor detects vibration along at least one axis of the motor. The sensors are oriented such that the polarity of each sensor is reversed. The pairs of sensors may be used to isolate specific vibrations within the motor. According to another embodiment, a sensor may be mounted directly to the motor shaft. The sensor on the motor shaft directly detects vibrations along the motor shaft. Optionally, a second sensor may be mounted to a fixed location within the motor housing, and the combination of the sensor on the motor shaft and the sensor at a fixed location may be used to isolate specific vibrations within the motor. A motor controller may adjust operation of the motor to reduce the isolated vibration.
摘要翻译：公开了一种用于监测电机振动的改进系统。根据一个实施例，传感器定位在与电动机轴正交的平面中，并且每个传感器沿着电动机的至少一个轴检测振动。传感器被定向成使得每个传感器的极性相反。传感器对可用于隔离电动机内的特定振动。根据另一个实施例，传感器可以直接安装到电动机轴上。电机轴上的传感器直接检测电机轴的振动。可选地，第二传感器可以安装到电动机壳体内的固定位置，并且电动机轴上的传感器和固定位置处的传感器的组合可用于隔离电动机内的特定振动。电机控制器可以调节电机的运行，以减少隔离振动。

摘要： Aspects of the present invention provide systems and methods using precise timing relationships between nodes in computer networks to generate mappings depicting the physical arrangement or ordering of nodes in the computer networks. The technical effect is by tracking the timing delays between nodes as observed by an individual node, and collecting such information together for subsequent processing, nodes may receive and/or construct an entire physical network topology using an algorithm accordingly.
摘要翻译：本发明的方面提供使用计算机网络中的节点之间的精确定时关系的系统和方法来产生描绘计算机网络中节点的物理布置或排序的映射。技术效果是通过跟踪单个节点观察到的节点之间的定时延迟，并将这些信息收集在一起用于后续处理，节点可以使用相应的算法接收和/或构建整个物理网络拓扑。
