Fundamentals of Electric Machines for Automotive Applications C1870

As the electrification of automobiles is on the rise, it is imperative that the capabilities and limits of the associated devices and systems be understood at a higher level than previously considered adequate. For example, the Tesla Model S has 62 electric machines while the Model X has 70! They propel the vehicle and provide comfort too. Their design must reflect the worst case operating scenarios, duty cycles, environment, country of use and its standards, etc. Robust design of every component of a system requires a clear understanding of the fundamentals as well as the working knowledge of all interface equipment including the latest in applicable material and cooling technologies. Since the multidisciplinary challenges in designing an electric machine must meet often-conflicting requirements such as cost, efficiency, size, weight, reliability, etc., it is important that an engineer with specialization in one discipline has working knowledge of other relevant disciplines along with the latest analysis techniques. The goal of this course is to introduce the fundamental physics-based principles that govern the operation of electric machines.

Learning Objectives
By attending this seminar, participants will be able to:
  • Describe the operating principles of an electric machine
  • Provide examples of conflicting requirements
  • Explain the role of team members and the need for a multidisciplinary approach to design, build, test and successfully produce an electric machine
  • Choose the right electric machine for a given application
  • Identify the different categories of DC and AC machines
  • Identify the major differences between the different type of electric machines such as DC brushless, induction, PM, reluctance machine, etc.
  • Define/identify the torque/power vs. speed requirements for a specific functionality
  • Identify key subsystems of an electric machine such as stator, rotor and the auxiliaries including their components

Who Should Attend
This course is designed for engineers and managers who deal with linear or rotary motion either to convert electrical power to mechanical power or vice versa but have little or no background in how an electric machine works either independently or in a system. Gaining this familiarity and fundamental understanding could help avoid making wrong decisions that can adversely impact the company financials as well as reputation.

An engineering degree is desired; other individuals who are knowledgeable of college level physics would also find the information valuable.
