在本文中，一个多参数，多传感器系统的综合电机状态监测已开发和评估报告的结果。开发的基于光纤布拉格光栅的系统允许同时监测关键参数，包括机器振动、转子速度、扭矩、旋转方向、沿着定子绕组和转子表面的温度分布以及定子波频率。这种全光学传感解决方案的设计与安装在电动机的严格限制兼容，并利用测量的光学性质和传感器材料的绝缘性质来避免电气干扰问题。该系统比传统的传感器系统减少了部件数量，即，所有传感元件都包含在机器内，并由单个传感询问单元操作，从而降低成本并为用户提供方便的接口。该系统的设计，作为测试和评估的设备的传感系统已成功地集成到和测试的结果上permanentmagnet电机原型。
In this paper, a multiparameter, multisensor system for comprehensive electrical machine condition monitoring has been developed and the results of an evaluation reported. The fiber Bragg grating-based system developed allows for the simultaneous monitoring of key parameters including machine vibration, rotor speed, torque, spin direction, temperature distribution along the stator windings and on the rotor surface as well as the stator wave frequency. This all-optical sensing solution has been designed to be compatible with being fitted in the tight confines of an electric motor and uses the optical nature of the measurement and the insulating nature of the sensor material to avoid problems of electrical interference. The system reduces the component count over conventional sensor systems, i.e., all sensing elements are contained within the machine and operated by a single sensing interrogation unit, thereby reducing cost and allowing for a convenient interface for the user. The design of the system is presented, as are results on the testing and evaluation of the device the sensing system has been successfully integrated into and tested on a permanentmagnet motor prototype.
