Stator leakage inductance

Leakage inductance derives from the electrical property of an imperfectly-coupled transformer whereby each winding behaves as a self-inductance in series with the winding's respective ohmic resistance constant. These four winding constants also interact with the transformer's mutual inductance. The winding … See more The magnetic circuit's flux that does not interlink both windings is the leakage flux corresponding to primary leakage inductance LP and secondary leakage inductance LS . Referring to Fig. 1, these leakage inductances … See more Leakage inductance can be an undesirable property, as it causes the voltage to change with loading. In many cases it is useful.

WebFeb 1, 2024 · What is a motor’s leakage inductance? 13. Leakage inductance – A portion of a motor’s inductive properties; synonymous with flux or voltage losses. Voltage loss results from voltage that is dropped across the motor’s conductors, yet produces no flux to link stator and rotor. WebJul 7, 2024 · Lm is the stator inductance fluctuation. The fluctuation of self-inductances (Laa, Lbb, Lcc) of stator windings and the fluctuation of mutual inductances (Lab, Lbc, Lca) between each two stator windings are always the same value (i.e., Lm). Please refer to the equation Laa, Lbb, Lcc, Lab, Lbc, and Lca on the documentation page. 3. WebSep 1, 2024 · All permeance values are collected to obtain stator inductance (L 1).
