Design and Implementation of a Remote Lab for Investigation of DC Motors

The last two years and the COVID-19 situation showed the need to ensure sustainable engineering education via the use of virtual and remote laboratories. The aim of the article is to design a laboratory model for studying the characteristics of DC electric motors. The implementation is based on different well know solutions, such as Raspberry PI, ESP32, power modules and sensor. The communication is based on the TCP/IP protocol and the control of the power modules is implemented using PWM. The IoT implementation of the lab is based on the Home Assistant platform, which allows monitoring and control of remote devices. The study also presents the schematic diagram of the virtual laboratory system, which allows to explain and substantiate the role and behavior of each component.
