Experiments with electrical motors in distance learning environment: Operating lab-volt electro-mechanical system using web-based tools from national instruments

Recent years gave a significant boost to distance learning (on-line) educational delivery. However, laboratory component was represented by simulation or remote operation of either static or small-size dynamic devices ^1,2. Few advances have been made in remote control and monitoring of large dynamic electro-mechanical systems, such as electric motors and/or drives. This paper concentrates on remote control of a group of electro-mechanical devices (variable power supply, electric motor, dynamometer, and instrumentation) integrated in one complex as well as visualization of their control parameters (such as voltage, speed, torque, current, and power). The paper also discusses log-on security procedures, hardware and software development, video streaming to ensure quality video and sound, and teaching methodologies to provide successful laboratory delivery.
