This article details the development and deployment of a wireless Internet of Things (IoT) framework designed for monitoring the status of traction motor drives in electric vehicles (EVs). The construction and experimental validation of a prototype, which utilizes an ESP8266 microcontroller to gather data on motor vibration, current, and temperature for motor condition assessment, are explored. The IoT infrastructure has been crafted utilizing readily available commercial components and an open-source software ecosystem, ensuring efficient and robust data collection with minimal energy usage. The data procured by the IoT framework is transmitted to a cloud-based server instantaneously. Trial outcomes indicate the system's proficiency in capturing critical motor parameters, uploading them to the cloud, and issuing instant alerts to operators upon the detection of any motor irregularities. Leveraging IoT advancements allows for proactive and remote planning of traction motor maintenance, bolstered by comprehensive data acquisition and analytical processes. Moreover, the implementation of innovative energy-saving measures ensures that the sensor node's battery consumption is markedly low, making it an ideal choice for mobile applications.
