525.652.8VL - Electric Machines and Control for Electrification

Course Structure

The course materials are divided into modules which can be accessed by clicking Modules on the course menu. A module will have several sections including the overview, content, readings, discussions, and assignments. You are encouraged to preview all sections of the module before starting. Most modules run for a period of seven (7) days. You should regularly check the Calendar and Announcements for assignment due dates.

Course Goals

To identify and describe various modern electric motor technologies used in todays electrification projects and build motor control algorithms.

Course Learning Outcomes (CLOs)

• Analyze single phase and three phase electrical circuits.
• Analyze magnetic circuits
• Describe principles of electromechanical energy conversion.
• Explain different types of AC motors used in electrification and their principles of operation
• Design motor control implementations including vector control
• Design motor control implementations including vector control
• Describe advanced topics concepts such as bearing currents and functional safety
• Create Matlab/Simulink and Simscape models to simulate electrical and electromechanical systems and controls

Textbooks

The course does not require text books. Class notes would be adequate.

For reference, students may use  the following books.

• “Principles of Electric Machines & Power Electronics,” P.C. Sen
• “Vector Control & Dynamics of AC Drives,” D. W. Novotny & T. A. Lipo 

Required Software

We will be using Matlab tools including Simulink and Simscape Electrical. Familiarity with these tools is nice to have at the start of the class, but not necessary. Please install these tools on your computer ahead of the first class, as we will start using during the first class.

Student Coursework Requirements

• Each module will contain a graded assignment. Weekly assignments will vary depending on module learning objectives. (30% of total grade)
• Graded quizzes/assessments will be given after Modules 3, 6, and 9. These will assess students’ achievement of the learning objectives in modules 1-3, 4-6, and 7-9 respectively. (45% of total grade)
• A final exam will be given on Week 14.  (25% of the grade)

Grading Policy

P uses a +/- grading system (see “Grading System”, Graduate Programs catalog, p. 10).

Course Policies

Students are encouraged to work collaboratively in completing the weekly assignments.

Academic Policies

Deadlines for Adding, Dropping and Withdrawing from Courses

Students may add a course up to one week after the start of the term for that particular course. Students may drop courses according to the drop deadlines outlined in the EP academic calendar (https://ep.jhu.edu/student-services/academic-calendar/). Between the 6th week of the class and prior to the final withdrawal deadline, a student may withdraw from a course with a W on their academic record. A record of the course will remain on the academic record with a W appearing in the grade column to indicate that the student registered and withdrew from the course.

Academic Misconduct Policy

All students are required to read, know, and comply with the Johns Hopkins University Krieger School of Arts and Sciences (KSAS) / Whiting School of Engineering (WSE) Procedures for Handling Allegations of Misconduct by Full-Time and Part-Time Graduate Students.

This policy prohibits academic misconduct, including but not limited to the following: cheating or facilitating cheating; plagiarism; reuse of assignments; unauthorized collaboration; alteration of graded assignments; and unfair competition. Course materials (old assignments, texts, or examinations, etc.) should not be shared unless authorized by the course instructor. Any questions related to this policy should be directed to EP’s academic integrity officer at ep-academic-integrity@jhu.edu.

Students with Disabilities - Accommodations and Accessibility

Johns Hopkins University values diversity and inclusion. We are committed to providing welcoming, equitable, and accessible educational experiences for all students. Students with disabilities (including those with psychological conditions, medical conditions and temporary disabilities) can request accommodations for this course by providing an Accommodation Letter issued by Student Disability Services (SDS). Please request accommodations for this course as early as possible to provide time for effective communication and arrangements.

For further information or to start the process of requesting accommodations, please contact Student Disability Services at Engineering for Professionals, ep-disability-svcs@jhu.edu.

Student Conduct Code

The fundamental purpose of the JHU regulation of student conduct is to promote and to protect the health, safety, welfare, property, and rights of all members of the University community as well as to promote the orderly operation of the University and to safeguard its property and facilities. As members of the University community, students accept certain responsibilities which support the educational mission and create an environment in which all students are afforded the same opportunity to succeed academically.

Classroom Climate

JHU is committed to creating a classroom environment that values the diversity of experiences and perspectives that all students bring. Everyone has the right to be treated with dignity and respect. Fostering an inclusive climate is important. Research and experience show that students who interact with peers who are different from themselves learn new things and experience tangible educational outcomes. At no time in this learning process should someone be singled out or treated unequally on the basis of any seen or unseen part of their identity. 
 
If you have concerns in this course about harassment, discrimination, or any unequal treatment, or if you seek accommodations or resources, please reach out to the course instructor directly. Reporting will never impact your course grade. You may also share concerns with your program chair, the Assistant Dean for Diversity and Inclusion, or the Office of Institutional Equity. In handling reports, people will protect your privacy as much as possible, but faculty and staff are required to officially report information for some cases (e.g. sexual harassment).

Course Auditing

When a student enrolls in an EP course with “audit” status, the student must reach an understanding with the instructor as to what is required to earn the “audit.” If the student does not meet those expectations, the instructor must notify the EP Registration Team [EP-Registration@exchange.johnshopkins.edu] in order for the student to be retroactively dropped or withdrawn from the course (depending on when the "audit" was requested and in accordance with EP registration deadlines). All lecture content will remain accessible to auditing students, but access to all other course material is left to the discretion of the instructor.
