This case exemplifies the Hamdi principle: Small changes in materials and gaps yield disproportionate gains.
: Uses a vast array of examples to illustrate the complete design process.
Applying Hamdi’s method:
The phrase "Design of Small Electrical Machines Hamdi" is not merely a textbook citation; it is a design philosophy. Hamdi taught us that small machines are not scaled-down large machines. They have their own physics, their own material constraints, and their own thermal crises.
Where other texts get lost in complex finite element analysis, Hamdi offers closed-form solutions specifically for fractional horsepower machines. He dedicates significant space to the choice of materials —specifically the trade-off between high-permeability steel (expensive, fragile) and standard silicon steel (cheap, robust).
Hamdi’s later writings (collected in Advances in Small Machine Design ) warn against:
