Magnetic flux density distribution in axial flux machine cores [PDF]
IEE Proceedings - Electric Power Applications, 2005 [Abstract]: A three-dimensional analytical model is presented to evaluate the magnetic flux density distribution in the core of an axial flux machine. The model predicts significantly higher flux density near the outer radius of the core than that at the

Comparison of Two Finite-Permeability Subdomain Models for Surface-Mounted Permanent-Magnet Machines
IEEE Access, 2023 Subdomain models have been widely used to quickly model the fields and the torque of surface-mounted permanent-magnet machines (SMPMMs). Nevertheless, when magnetic saturation occurs, those models which assume the permeability of the iron parts to be ...

Approximation of Hysteresis Changes in Electrical Steel Sheets
Energies, 2021 This paper describes a simple method of approximating hysteresis changes in electrical steel sheets. This method is based on assumptions that flux density or field strength changes are a sum or a difference of functions that describe one curve of the ...

An Accurate Flux Density Scale from 50 MHz to 50 GHz [PDF]
, 2016 The flux-density scale of Perley & Butler is extended downward to ∼50 MHz by utilizing recent observations with the Karl G. Jansky Very Large Array (VLA) of 20 sources between 220 MHz and 48.1 GHz, and legacy VLA observations at 73.8 MHz.

Characteristics of Low-Latitude Coronal Holes near the Maximum of Solar cycle 24 [PDF]
, 2017 We investigate the statistics of 288 low-latitude coronal holes extracted from SDO/AIA-193 filtergrams over the time range 2011/01/01 to 2013/12/31. We analyse the distribution of characteristic coronal hole properties, such as the areas, mean AIA-193 ...

A Mariotte-based verification system for heat-based sap flow sensors [PDF]
, 2012 Determination of the accuracy of commonly used techniques for measuring sap flux density in trees often presents a challenge. We therefore designed and built a verification system for heat-based sap flow sensors typically used at stem level.
