Welcome to the learning path for permanent magnet motors. This guide provides a roadmap through the topics covered on this site. Each section builds on the last, so we recommend following the sequence below:
Fundamentals
Begin with an overview of motor types and the dq model.
Design
Learn how to size a motor and interpret torque-speed envelopes.
Control
Dive into field‑oriented control, maximum torque per ampere (MTPA), and field-weakening.
Losses
Understand where inefficiencies arise and how to read efficiency maps.
Interactive Labs
Experiment with sliders and plots to see how parameter changes impact motor behaviour.
This site is under active development. If you see an Assumption callout, we explicitly state the simplifying assumptions made. A Pitfall callout warns you about common mistakes or misunderstandings. Feel free to explore pages in any order if you are already familiar with some topics.
