Distribution of electromagnetic forces in separately excited dc and ac induction machines

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
this paper provides an in-depth analysis of distribution of the electromagnetic forces in separately excited dc and ac squirrel cage induction machines. Investigation of local forces acting on the stator and rotor core and windings will shed light on inherent similarities in the mechanism of force generation in two families of electrical machines. This

Calculation of Nb3Sn superconducting magnet's inductance and distribution of electromagnetic force

2010 Second Pacific-Asia Conference on Circuits, Communications and System, 2010
The electromagnetic force distribution of Nb 3 Sn superconducting magnet is analyzed and obtained when the magnet is in the maximum magnetic field, then the request of magnet's structural strength is offered. Next, three methods of calculating the coil inductance are presented which are flux method, energy method and classical formula method.

Study on electromagnetic force in interior permanent magnet synchronous machine with distributed windings

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
With the development of electric vehicles, more and more attentions have been put on understanding and attenuating the noise, vibration, and harshness (NVH) of traction machines. NVH in machines are mainly caused by the electromagnetic force, which is complex vector functions of both time and space, and models are desired for accurately evaluating its ...

Short-Circuit Electromagnetic Force Distribution Characteristics in Transformer Winding Transposition Structures

IEEE Transactions on Magnetics, 2020
For continuous or spiral windings which feature multiple continuously transposed conductors (CTC) wound in parallel, the transposition structure is commonly used to suppress circulation between conductors. This introduces a local asymmetry in transformer windings. Fault analyses have shown that building an asymmetric structure in transformers increases

Influence of Contacting Schemes on Electromagnetic Force and Current Density Distribution in Armature

IEEE Transactions on Plasma Science, 2019
The current density and electromagnetic force distribution of the armature directly affect the performance of electromagnetic railgun. In this paper, the electromagnetic thrust, electromagnetic pressure, and current density of the C-shaped armature and H-shaped armature are calculated, respectively, by the finite-element method under different Armature–

Equivalent Rectangular Element Method for Regularized Distribution of Electromagnetic Body Force

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
In this paper, an observation of body force distribution and its regularized one are dealt with. The calculated body force field is irregularly distributed in general because of its nature. For obtaining regularized force distribution, equivalent rectangular element (ERE) method is proposed. It can be easily implemented in the stage of post-processing.
