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 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Understand the relationship between electric current and magnetic fields
  • Understand how magnetic fields can be established in various types of electromechanical devices
  • Understand how DC motors, induction motors, and synchronous motors and generators operate
  • Understand how single and three-phase transformers work
  • Know how to interpret nameplate data for motors and transformers
  • Know how diodes and SCRs operate
  • Know how a transistor operates as a switch
  • Know how to control the speed of DC and AC motors
  • Know how split-phase and capacitor start single-phase motors work
