# How to design and optimize machine geometry and dimensions, including tolerances # Frequent interjections of "design wisdom" # Hundreds of rules and guidelines
# System configuration # How motors work with inverters and electronics # Just enough theory to explain what we're doing
# Windings # Classic formulas for estimating and checking
Overview # Aims — Learn how to design modern electric machines with SPEED — Discover new features in SPEED # What type of electric machine? — Brushless permanent-magnet N All types : BLDC, BLAC, IPM, SPM, Radial and Axial-flux N Special attention to generators and regeneration — Wound-field AC generators — Induction machines — Synchronous reluctance machines — Switched reluctance machines — Drives & Controls are covered for all machine types — Generating operation covered for all machine types The SPEED software system # Why is this type of course important? P We're on a historic boundary between classical analysis and modern numerical methods P We need to understand how these are related and how to make them work together # Is this course about design, or theory, or SPEED software? P The SPEED software is used to practice design and illustrate theory P It works for new engineers as well as experienced engineers # Who presents it? — Prof. Tim Miller, FIEE, founder of SPEED — In the industry since 1967 # Will I get a SPEED training certificate? — Yes # What kind of engineer is this course designed for? — Electrical and mechanical engineers involved in design and manufacturing electric machines will WINDING EDITOR

get instruction that is directly useable in their work Managers, control engineers, power-electronics engineers will also get a deep insight
Learning Electric Machine Design P Shortage of electric machine engineers Few universities teach this subject experienced engineers are retiring
Learning for work in the factory
P New types of motor — difficult to calculate P Electronics is included P Textbooks are written by academics, not designers Ivory tower Fundamental theory
# Old system has long ago run dry # The drips have stopped # This does not work anymore
# We can't find the talent # So what can we do? — Forget the search for specialists — Get good people in any discipline — Learn on the job, in the factory — Keep the learning experience going — Do all this with SPEED
