IMPORTANT MOTOR DESIGN OFFERING NOW HERE !!
AC Machine Design - Taking Theory to Practice
July 23 23-25, 2008
Marriott Hickory Ridge Conference Center Center, Lisle, IL --CHICAGO AREA!
Learn practical AC Machine design concepts by understanding and applying motor operation principles, academic analysis theory and manufacturing limitations
Foundations of AC Machine Design Methods
Putting Magnetic Fields of AC Windings to Work
Performance & Loss Calculations
Effective Use of Materials & Methods
Design for Efficiency or Power Density
Computer Aided Engineering for AC Machine Design
Objectives and Benefits
This course will combine electrical, magnetic, mechanical, and thermal principles to increase your understanding of AC machine design.
Academic theory will be reduced to practical results and manufacturing constraints are taken into account. Special emphasis will be on
design differences of line-supply motors and application-specific motors, and how to achieve specifications such as efficiency, power
density, etc.
The primary goal of this course will be to build a solid foundation of AC machine design concepts that can be used to produce realistic
design results, manufacturability considered. It will also provide the essential background needed to learn and apply the latest motor
research & development technology, advanced analysis techniques and new control concepts.
Those who will benefit:
• Motor design engineers
• Application engineers
• Suppliers to motor manufacturers
• Control engineers
• Engineering managers
• Others who design, manufacture, specify and use AC machines
Attendees should have a good understanding of AC machine operation and construction with the equivalent of a technical B.S. degree.
Understanding of advanced motor theory and motor control techniques will be helpful but not essential.
Instructors:
Dr. Keith W. Klontz is President and Founder of Advanced MotorTech LLC, a computer-aided engineering (CAE) services company with emphasis on
electric machine and magnetic component design. He holds BS & MS degrees in Electrical Engineering from the University of Illinois, Champaign-
Urbana, and a PhD in Electrical Engineering from the University of Wisconsin-Madison. Dr. Klontz is a world-recognized expert in electric machine
design and has over 35 years hands-on experience with electric machine design engineering, from concept to performance to failure analysis. He has
been involved in the research, development and testing of very high performance machines from 10 Watts to 8 MW, with speeds ranging from angle
positioning torque-motors to 60,000 rpm machines. Recent work includes implementing CAE tools and developing design techniques for the design of
permanent magnet alternators, brushless d.c. motors, brush d.c. motors, high efficiency induction motors, and very high power density machines.
Dr. Howard Li is a Senior Engineer at Advanced MotorTech LLC. He holds BS and MS degrees in Electrical Engineering from Shenyang University
of Technology, China, and a PhD degree in Electrical Engineering from Clarkson University, USA. Dr. Li has more than 5 years of experience in the
design, simulation, modeling, and development of a wide variety of conventional and innovative machines, drives, controls and electromechanical
components. His work has ranged from linear generators deriving power from ambient vibration to FEA short-circuit transient analysis of megawattclass
machines, to 3D analysis of transverse-flux machines based on new SMC core materials. His main fields of interest are CAE electrical machine
design, modeling and analysis of motor drives, thermal analysis and coupled-physics field analysis.
