A remote operation and maintenance system of intelligent motor manufacturing based on cloud platform was designed to meet the requirements of remote operation and maintenance of intelligent manufacturing of motor devices. The system architecture, information architecture and experimental verification platform of remote operation and maintenance system were described in detail. The remote operation and maintenance system could collect motor parameter information in the process of motor manufacturing and field application, and realize the operation and maintenance management of the whole life cycle of the motor. The application of the platform will help enterprises improve the quality of motor production, reduce motor operation and maintenance costs, speed up the response of motor operation and maintenance services, improve aftersales service level, and improve the level of intelligent manufacturing of motor devices.
