EE 253 - Analysis and Control of Electromechanical Devices

3 lecture hours 2 lab hours 4 credits
Course Description
This course introduces the non-electrical engineering students to electromechanical devices such as motors and transformers, as well as control of these devices using programmable logic controllers and variable speed drives. Laboratory work emphasizes motors and their control. (prereq: EE 201 , MA 137 , or MA 225 )
