The Analysis of Leakage Magnetic Field in the Large-Capacity Transformer
Advanced Materials Research, 2012With the increase of transformer capacity, local overheating caused by leakage magnetic field affects the normal work and safe problems of transformer. How to reduce the additional loss and eliminate local overheating must be paid full attention to the design and manufacturing process of large transformer.

2016 IEEE Conference on Electromagnetic Field Computation (CEFC), 2016
When a magnetically shielded room (MSR) to shield leakage fluxes of electric machines is designed by using magnetic field analysis, it is difficult to represent the leakage magnetic field of an electric machine accurately. In this paper, a method of modeling it using a simple solid model with multiple magnetization vectors is proposed.

Magnetic leakage fields calculated by the method of finite differences
NDT International, 1985Abstract Is the signal indicating magnetic leakage fields proportional to the depth of the crack? This questions needs to be answered to show the effectiveness of the testing method. However, contradictory reports have appeared in the literature in the past few years.

Effects of leakage flux on magnetic fields of interior permanent magnet synchronous motors
IEEE Transactions on Magnetics, 2001This paper presents a magnetic circuit model for an interior permanent magnet (IPM) synchronous machine. The model includes each portion of magnetic flux paths, especially the leakage flux paths around the magnets in the rotor. The magnetic field quantities are expressed analytically in terms of the reluctance ratio /spl beta/ and the leakage flux ...
