A Novel Approach to Calculate Squirrel Cage Induction Motor Rotor Leakage Inductance
2006 Canadian Conference on Electrical and Computer Engineering, 2006The end ring leakage inductance of an induction machine is computed either by using an empirical formula or by using very complicated mathematical techniques. In this paper, an alternate method to compute this inductance using Winding Function Approach (WFA) and three dimensional Finite Element (3DFE) using Maxwell is described. The method is deemed to

The influence of cooling ducts on the leakage inductances of induction machines
IET 7th International Conference on Computation in Electromagnetics (CEM 2008), 2008In this paper the influence of the cooling ducts on the leakage inductances, and therefore on the breakdown torque, in induction machines is discussed. This effect is typically a three-dimensional one, and one has to analyse numerous geometrical variants.

Advanced Leakage Inductance Model for Transformer Transient Simulation
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018Transformer models in EMTP which provide inter-phase mutual inductance leakage representations have deficiencies with respect to core modeling. Parameter estimation is also a concern when no or incomplete sources of information are available. The "hybrid" transformer model in EMTP-ATP addresses these issues by allowing the integration of the leakage ...

Improved Power Transformer Performance using Leakage Inductance Shielding
2019 European Space Power Conference (ESPC), 2019This paper presents a novel technique to reduce the leakage inductance in transformers for switch mode power supplies. By introducing the leakage inductance shield, that reduces the leakage flux by means of Eddy current shielding, the leakage inductance is reduced by almost 15 % in a transformer for a 100 W, 100 kHz flyback converter.

MATLAB simulation of induction machine with saturable leakage and magnetizing inductances
Botswana Journal of Technology, 2005At high stator phase currents, the effect of saturation of the stator and rotor leakage inductances becomes noticeable to the extent that the conventional machine model fails to represent the dynamic performances of induction machine. In this paper, a commercial software package, MATLAB is used to simulate the dynamic behaviour of induction machine ...

Estimation of the leakage and magnetizing inductances of Induction Motors
2009In addition to the IEEE standard test procedure for induction motors (IM), several advanced methods have been presented to achieve higher accuracy on parameters estimation. Some of them allow to estimate with high precision only a specific parameter, while others improve the parameters estimation at the price of high computational efforts and time due ...
