Power Devices and dc Motor Control EEC476

The Power Devices and dc Motor Control kit has been designed to provide a course of study covering device characteristics and dc motor control methods, including PWM motor control and is used in conjunction with the unpowered EEC470 Construction Deck. The hardware includes a dc motor module with optical incremental encoder and eddy current brake. Comprehensive assignments cover theory, objectives, procedure and typical experimental results on a range of topics related to Power Devices and dc Motor Control.
