Overview

This webinar presents an overview of three robust and scalable solutions: the induction motor, the electrically excited alternator, and the switched reluctance motor. 

  • The induction motor offers proven reliability, ruggedness, and cost-effectiveness, making it well suited for demanding duty cycles
  • Electrically excited alternators eliminate permanent magnets while enabling precise control of excitation and high efficiency across wide operating ranges
  • Switched reluctance motors provide a simple, magnet-free rotor structure, high fault tolerance, and strong performance in harsh environments, albeit with challenges in torque ripple and acoustic noise

 

What You Will Learn

  • Outline of the key components of induction, electrical excited and switched reluctance rotating machine model, including the electrical, magnetic, mechanical, and thermal domains
  • Parameter identification, from winding resistance and inductance to rotor inertia and back-EMF profiles
  • Both analytical and finite element approaches, comparing their accuracy, complexity, and computational requirements
  • Coupling between electromagnetic and thermal effects for high-performance applications

 

Who Should Attend

Engineers and researchers looking to build or improve their motor modeling capability. We will also share the best practices and common pitfalls to avoid.
