Registration: $450 before January 7th, 2018; $550 after January 7th Register for both workshops: $650 before January 7th; $750 after January 7th The Magnetics Bootcamps focus on teaching you the basics of magnetics with an emphasis on permanent magnets. Basic Bootcamp: If you need to understand magnets better for your job, want to get more from the conference presentations, or are new to the field, the Basic Bootcamp is the perfect place to start. Assumes that one has little or no background in magnetics. The Basic bootcamp will cover the essential fundamental magnetic concepts such as hysteresis, the nature of magnetism, units, basic magnet processing, magnetizing and thermal effects. Advanced Bootcamp: If something more advanced is what you are looking for, attend the Advanced Bootcamp. Assumes someone has either taken a previous Basic Bootcamp, or has some technical understanding of magnetics. After a brief review of the basics, covered topics include self-demagnetization and loadlines, rare earth raw materials and their pricing, advanced processing techniques, manufacturability, design basics, case studies and what’s new on the horizon. Stan’s professional life, just over forty years, has been almost evenly divided between the permanent magnet and rare earth industries. For the last sixteen years, he has run a consultancy called Spontaneous Materials, serving clients in these industries on a wide variety of technical and commercial projects. His previous employers include Molycorp, Magnequench, Hitachi Magnetics, Crucible Magnetics and Recoma. Dr. Trout is a registered professional engineer, in Pennsylvania and Colorado, holds a B. S. in Physics from Lafayette College and a Ph.D. from the University of Pennsylvania in Metallurgy and Materials Science. He is a member of the MCMA, the UK Magnetics Society and a life senior member of the IEEE Magnetics Society.
Registration: $295 before January 7th, 2018; $395 after January 7th Register for both DriveTech workshops: $495 before January 7th, 2018; $650 after January 7th This introductory course is to provide fundamental concepts of electric motors and motor control techniques along with introduction of new advanced technologies. The objective of this course is for who want to learn fundamental principles and basic knowledge on electromagnetic torque production theory, construction and operation of DC, PM Brushless, Reluctance and Induction motors. This course also discusses control electronics hardware and control algorithms, feedback control and servo systems, PID regulators and their tuning procedure. The course starts with the magnetic and mechanical structure of the various motor types (including DC, Brushless, induction and SR motors) to understand torque production mechanism and required commutation strategies. Discussion is followed by control of power semiconductor switches, PWM techniques, motor drive topologies, drive hardware, control algorithms, and software implementation, as well as current and speed control. The content also explains pros and cons of drive technologies such as 6-step vs. sinusoidal, voltage drive vs. current drive, phase current regulator vs synchronous regulator, PID vs other controllers, sensored vs sensorless control, etc. From the author’s long experience in research and development of many different types of drives, practical and useful procedures in selecting control method, rule-of-thumb design rules, control system structure and tuning, performance vs. cost tradeoff, etc will be discussed. Course contents include
- Basics of DC and Brushless Motor Control
- Structure and Operation of DC motors
- General Mechanism of Electromagnetic Torque Production
- Brushless PM motors
- 6-Step Commutation and Switching Schemes
- Power Electronics and Drive Hardware
- Comparison between Trapezoidal and Sinusoidal control

- Nested Loop – Velocity and Position Control
- Various Current Control Methods
Registration: $495 before January 7th, 2018; $650 after January 7th There is currently wide and renewed interest in the research and development of electrical machines. On-going efforts are fueled by the need for the new generations of “green” products, such as hybrid and electric vehicles and ultra high-efficiency industrial and home appliance motors. The workshop reviews best practice for design of brushless permanent magnet (BPM) motors. Course contents include:
- Mix of analytical and numerical method to give fast and accurate electromagnetic and thermal simulation methods.
- How best to integrate the electromagnetic and thermal simulation into the design process.
- Initial sizing followed by detailed electromagnetic and cooling system design.
- Concept design studies.
- Design optimization for a complex duty cycle rather than a specific torque and speed.
- Embed manufacturing issues into the design process.
- Model validation.
- Step-by-step guide on the how to design for a specification with design decisions explained including corresponding theory.
- The example specification used on the workshop is for a small electric vehicle traction application however the procedure is common for most variable speed inverter fed BPM motor designs.
Registration: $295 before January 7th, 2018; $395 after January 7th Register for both DriveTech workshops: $495 before January 7th, 2018; $650 after January 7th This course will provide in-depth knowledge and skills in control theory, algorithms and software structure to design various high performance AC motor drives and control systems. The course is intended for experienced engineers who have prior exposure in motor drive design, or have basic knowledge in DC and AC motor control theory & feedback control theory as outlined in the morning workshop, “Overview of Basic concepts and technologies on Motor Drives & Motion Control”. The course starts with the basic principles of FOC (Field Oriented Control, aka Vector Control), reference frame transform theory, and dynamic motor model of PM motors and induction motors. Then the discussion continues in applying the FOC principles to PM synchronous motors, IPM, and Induction motors. Discussion is followed by various advanced motor control techniques for high performance and high energy efficiency including Space vector Modulation, Field-weakening operation, and Sensorless control algorithms. The last part of this course will be dedicated to additional topics of interest from participants, such as other advanced control methods or control of special motor types (such as Reluctance motors), Other applications of FOC concept (like Generators, Inverters, and Active Rectifiers), Modeling and Simulation, etc. The course material is heavily modified and enhanced with many new topics from past similar courses by the lecturer. Course contents include: 1. Field Oriented Control Theory
- Basic Principles of Smooth Torque production in DC and AC Motors
- Frame Transformation
