Objective

Course Code

ELK 488E

 Electric motors are extensively used in many stages of industrial processes. Since 70% of global electricity generation is consumed by electric motors, it is essential to design efficient electric drives to increase system reliability and to lower operational costs in a plant. Substantial energy savings can be obtained by employing advanced control and semiconductor power converter technologies combined with a suitable selection of electric motor type and rating. This course is intended primarily to provide a fundamental knowledge of modeling, analysis and integration of mechanical and electrical components and to introduce various aspects of design and control techniques in electrical drive applications, such as manufacturing lines, electric transportation, air-conditioning and ventilating, crane and hoist applications, etc.

    Grading

    Grading polciy and rules

    		RESTRICTED ACCESS ("username" and "password" necessary)
    Grading and Weigths: Your Grade will be determined from the weighted averages of 1 (one) Project, 2 (two) Midterm Exams and a Final Exam. The weights are:
  • Project + Presentation 30%
  • Mid-Term Exams 30%
  • Final Exam 40%
    Rules:
    Attendance: To be able to take the final exam, 70% of attandance is required.
  • All exams will be closed book. No crip sheet is allowed.
  • Submission of group projets and a poster presentation is required. Otherwise it will result in a grade of "VF" (This means that the student will not be allowed to take the final exam.)
