This paper presents core loss analysis of 3-phase induction motors used for industry applications. The core loss is affected by the time rate of the change of magnetic flux density. Generally core loss is spread out in stator and rotor core. And, rotor core toss is less than stator core because of constant field flux density of rotor. Tooth core loss density is large than yoke core loss because tooth...
Wind generator has a typical characteristic of more pole-pairs number on the occasion of low speed and high power, and DSEG should adopt multi-pole-rotor structure for the corresponding relation of pole-pairs number and rotor pole number. The increase of rotor-pole number leads to the obvious increase of core loss. Flux waveform of different part of 24-32-DSEG is analyzed in this paper, and core loss...
The work described in this paper is Io investigate the additional losses and consequent temperature in core ends in a turbo-generator wound with cables. Electromagnetic calculations are made with 3D FE models, which include the lamination material with anisotropic properties both in magnetic permeability and electric conductivity. The models also include the geometry of the stator teeth and eventually...
