**Lectures:** Mon; Wed; 16:00 – 17:30

West Mall Swing Space, Room 406

This is a beginning level graduate course that may be useful for all students interested in application of electric machines, mechatronics, and power area in general. The course focuses on modeling power systems components and electric drives. During the course students will be working on several assignments that will include development of simulations of electrical machines, drives, and associated controls. Recommended software for working on class assignments is Matlab/Simulink.

**Cheating
Policy:** The academic enterprise is founded on honesty, civility, and
integrity. This also means you should not cheat, copy, or mislead others about
what is your work. Students are encouraged to discuss among themselves the
problems in each assignment. However the turned-in assignment reports must show
the individual work and reflect the individual understanding of material by
each student.

**Reports
suspected of cheating will not be graded. Cheating will result in zero mark and
may qualify for withdrawal form the course and/or suspension from the
University.**

**Grades:**

This course would not have mid term or final exams. The final grade will be based on all assignment reports.
