Overview

Power tools are used in industrial and DYI environments for drilling, cutting, grinding, and other applications. Brushless DC (BLDC) motors are widely used in power tools due to their high efficiency, compact size, and precise control.Accurate modeling of a BLDC motor is essential for performance optimization, control strategy development, and system integration. This webinar provides a practical overview of how to model a BLDC electric motor using modern simulation tools and techniques provided by Ansys​.

The modeling workflow covers circuit simulators, field solvers, and system-level tools, with guidance on selecting the appropriate level of detail for different design stages. Finally, the talk is brought to life with an example case study, demonstrating the step-by-step process of creating and validating a BLDC motor model using simulation software. ​

What You Will Learn

  • Outline the key components of a BLDC motor 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

This talk is aimed at engineers and engineering managers looking to build or improve their motor modeling capability, and it highlights best practices and common pitfalls to avoid.
