Study resources
- Estimation of Air Gap Length (Article) — Gives the approximate formula for air gap length in terms of pole pitch, air gap coefficient (1.12–1.18), and the fact that AT for air gap ≈ 70–75% of no-load AT. Explains advantages/disadvantages of…
- Length of Air Gap (Article) — Explains air gap length selection: how it affects magnetising current, power factor, overload capacity, cooling and noise. Gives formula Lg = 0.2 + 2√(DL) for small motors. Covers rules for rotor slo…
