Magnetic field and rotor impedance analysis of solid rotor induction motors using the multilayer analytical method

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
A multi‐layer analytical model for calculating the magnetic field and equivalent circuit parameters of solid rotor induction motors is proposed, which can consider the effects of saturation effect and end effect of the solid rotor. The accuracy of the analytical model is verified by finite element simulation and prototype test.

Towards an improved understanding of Ca–Mg carbonates with nonplanar surfaces: An experimental approach

open access: yesSedimentology, Volume 72, Issue 1, Page 100-131, January 2025.
ABSTRACT Saddle dolomite is a Ca–Mg carbonate characterized by curved crystal faces, curved cleavage and sweeping extinction under cross‐polarized light. Saddle dolomite and, generally, Ca–Mg carbonates with curved crystal faces, are often assigned to the burial (hydrothermal) realm and serve as proxy archives for hydrogeochemical processes in ...

Enrichment Mechanism of the Organic‐Rich Shale in Ediacaran Doushantuo Formation in Western Sichuan Basin, South China

open access: yesGeofluids, Volume 2025, Issue 1, 2025.
The Ediacaran Doushantuo Formation in South China has been increasingly recognized as a significant potential source rock for hydrocarbon reservoirs, particularly in relation to the overlying Dengying Formation. This study conducts a comprehensive geochemical analysis of the organic‐rich shale from the Ebian‐Xianfeng section within the Sichuan Basin ...

The strata and palaeo-geomorphology framework at the end of neoproterozoic and development mode of source rocks at the beginning of Cambrian in Tarim Basin, China

open access: yesJournal of Natural Gas Geoscience, 2017
Referred to the new recognition from petroleum exploration of the Sinian to Cambrian in South China, it could be considered that the distribution of the early Cambrian source rocks was controlled by the palaeo-geomorphology at the end of Neoproterozoic ...
