A genuine "better" PDF of a 500-page engineering textbook will be between 20 MB and 150 MB. If it is 2 MB, it is either a fake, a virus, or a text-only file missing all the crucial wiring diagrams.
Guy Séguier updated his books over the years to include more modern power electronics. While the physics of the induction motor hasn't changed, the presentation and examples have. Look for editions published by Lavoisier/Tec & Doc from the late 1990s or early 2000s.
Since Séguier’s style is dense and mathematical, use these parallel resources:
| Concept | Complementary resource (free) | |---------|-------------------------------| | Machine modeling | MIT OpenCourseWare – 6.685 Electric Machines | | Power electronics | “Power Electronics” by Daniel W. Hart (samples on Google Books) | | Industrial protection | Schneider Electric “Electrical Installation Guide” (free PDF) | | Exercises with solutions | “Problèmes d’électrotechnique” – Guy Séguier (same author) |
A physical copy of Electrotechnique Industrielle weighs approximately 1.5 to 2 kilograms. An industrial engineer rarely sits at a stationary desk. They are on the shop floor, in a control room, or on a train to a client site. The PDF version loads on a tablet, laptop, or even a high-end smartphone. Better mobility means better productivity.
Séguier’s original book had few solved exercises. Instead, use:
