2.1.2. Leakage Inductances

The magnetic coupling of a winding with itself is described by the leakage inductance *Lσ*. This coupling manifests itself in a reduction of the main flux. The essential parts of the leakage flux are the harmonic, the slot and end-face leakage flux, and the leakage flux in the tooth tip space. These effects are considered in an analytically calculated leakage flux factor *λ*S/R when calculating the stator and rotor inductances.
