Conclusion This paper proposes a motor energy management architecture which is composed of a data acquisition platform a condition monitoring platform an energy consumption and saving analysis platform a communication platform and a motor energy data management platform. Under the guidance of the architecture an in-service motor monitoring and energy management system is developed based on non intrusive monitoring technologies and wireless sensor networks. The system has two subsystems a data acquiring and analysis subsystem and a condition monitoring and energy management subsystem. To evaluate the in-service motor energy usage motor efficiency estimation methods are discussed. And a motor monitoring front-end device is developed with the implement of the methods introduced. The device is designed as three separate units including a sensing unit a processing unit and a communication unit. Such a flexible design could meet various requirements in the application. The wireless sensor network is a self-organized network with dynamic topology. As a lowcost robust and reliable communication network it is used to connect the front-end .
