Tool for instruction and learning on variable speed drives through the Internet

In this work, we present the development of an educational tool for instruction and learning on industrial variable frequency drives, which uses the resources of the remote laboratory of automatic control of the Universidad de León. An environment for simulation and operation was developed, so that faculty and students can access to a real physical system that comprises the drive, an AC motor and a load. Specifically, the load is a continuous conveyor belt where pieces or elements can be added to make it variable.
