Description
Methods of controlling AC motors beyond simple on/off control are explored. These include reduced voltage starting methods, electronic soft starting and speed control using adjustable frequency drives. General speed control of DC motors is also explored. Basic theory, set up and troubleshooting are supported through hands-on activities with actual industrial equipment.
