Topics • • • Optimization Magnetics and Magnetic Equivalent Circuits Inductor Design Force and Torque Electromagnet Design Magnetic Core Loss 3

Topics (Continued) • • • Transformer Design Distributed Windings Permanent Magnet AC Machine Design Thermal Equivalent Circuits AC Conductor Losses • We’ll not get through all of this 4

Before You Take This Course • Prerequisites ØUnderstanding of theory of operation of permanent magnet synchronous machines (brushless dc machines), a basic knowledge of electromagnetic fields • Software ØWe will be using Matlab extensively 5

Course Text • S. D. Sudhoff, Design of Power Magnetic Devices: A Multiobjective Approach, IEEE Press/Wiley, 2014. • ISBN 978 -1 -118 -48999 -4 • Written specifically for this course • We will use it extensively and follow it closely • Excellent bed time reading, though exciting parts may keep you up 6

Grading • Exam 1 – In class, 75 minutes, worth 15% of your grade. Date: TBD • Exam 2 – Final exam period, 75 minutes, worth 15% of your grade. Date: TBD • Homework – Periodically assigned. Worth 70% of your grade. 7

Homework • Homework sometimes is sometimes short problems, sometimes more of a project. • Late homework will be penalized at 20% per business day. It is due at the beginning of the period. • You may freely discuss your homework with other students; however, individual work is expected unless explicitly told otherwise (ex, a group homework) 8

In-Class Exam Policies • No computers, cell-phones, PDAs, slide rules, abacus, rulers, are allowed • A TI-30 X IIS calculator (see next slide) is allowed • There will be no crib sheet • Do not look past your own desk. Hats with front brims are not allowed • Makeup exams will only be rarely allowed in exceptional circumstances. They will be long. They will be challenging. They will not be curved. Not recommended. • Exams may be curved on a per test basis. 9

Exam Policies – Calculator • • Effective beginning in January 2015, the only calculator permitted for exams in ECE undergraduate courses (those at the 10000 – 40000 level) will be the Texas Instruments TI-30 X IIS scientific calculator. This is an inexpensive calculator with a 2 -line display, a fraction feature, one or two-variable statistics, simple conversions, and basic scientific & trigonometric functions. Students are encouraged to familiarize themselves with the use of this calculator well in advance of any exam. This policy addresses the potential for academic dishonesty given the features of many advanced calculators (programmability, large memory capacity, wireless communication, etc. ), thus ensuring the integrity of the exam. In addition, a common calculator provides a fair and uniform exam experience for all students 10

Cheating • At minimum, cheating will result in a zero on the assignment in question. • All instances of cheating, even suspected cheating, will be reported to the ECE Assistant Head for Education 11

Grade Distribution Philosophy • Fall 2013 (as example) ØA’s: 8 ØB’s: 4 ØC’s: 2 ØD’s: 2 ØF’s: 1 12

Final Notes • In the event of a worldwide pandemic, asteroid impact, global flood, or invasion of space-alien homework-eating cyborg super beagles, or other such event, class policies may be adjusted midcourse. Information will be posted on course web site in such a case. 13
