This article introduces a novel web-based DC motor laboratory, called NeTRe-LAB, to support teaching electrical machines. The NeTRe-LAB includes favorable animations to facilitate understanding characteristics of the DC motor, interactive DC motor models for instructive simulations, and web-based experiments with online monitoring features. To illustrate the current operations, remote access to an experimental setup of a DC motor has been provided and the speed control of it has been realized over Internet. The evaluation results have shown that the NeTRe-LAB presented in this study provides encouraging aspects, services, and support system for higher education. ß

This study presents development of the system architecture to perform laboratory experiments over the Internet for electrical engineering education. Design and implementation of four-quadrant speed control experiment for a direct current (DC) motor is given in the article as a sample remote experimental study. The system designed consists of four main parts as a client, a server, a data acquisition unit and an experimental set with a control unit. MATLAB web server (MWS) is used to send and receive data or graphics over the Internet. While the experiment is being operated, the real experimental set placed in the laboratory can be monitored by the remote user. Evaluation results show that the system designed accelerates the learning period, increases the concentration on the experiment and provides a safe environment for four-quadrant speed control experiment of a DC motor. ß

The paper analyzes the key features, performance, efficiency, and electrical characteristics of organic PV cells to highlight the latest trends and advancements by using comparative tables and a comprehensive SWOT analysis.
