This article pertains to dual stator winding induction machines (DSWIMs) modeling and proposes an equivalent electrical circuit for DSWIMs that considers the iron loss effect. It is proved that the iron loss in DSWIMs is comprised of two independent parts resulting from their winding sets.

New high voltage 2-pole concentrated winding and corresponding rotor design for induction machines
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015This paper presents a design of a two-pole high voltage induction machine with concentrated coils wound on twelve stator teeth. Using a combined wye-delta winding a magnetomotive force distribution with a low content of space harmonics is created. For suppression of still existing undesirable slot harmonics, a special interconnection of rotor bars is ...

The influence of three different damper winding configurations on unbalanced magnetic pull (UMP) in salient pole synchronous machines with rotor eccentricity has been investigated. Continuous and noncontinuous damper windings resulted in different damper winding currents, but their effect on the UMP was found to be very similar. Measurements of the UMP,

2019 IEEE Student Conference on Research and Development (SCOReD), 2019
Salient rotor field excitation flux switching synchronous motor (FEFSSM) could be considered as the most feasible candidate in high speed condition owing to their robustness and flux control ability. Nevertheless, the existing FEFSSM utilizes overlapped field excitation coil (FEC) and armature windings, the material cost, motor size and rise of copper ...

A Novel HTS Wind Generator Having Permanent Magnets Between the Rotor Pole-Tips
IEEE Transactions on Applied Superconductivity, 2019Superconducting direct-drive wind generators have been proposed as a possible approach for offshore wind energy application due to their inherent high torque density and small mass compared with conventional electrical machine. In this paper, a novel 10 MW high temperature superconducting (HTS) salient pole synchronous wind generator with additional ...

Test results of the world's largest four-pole generators with water-cooled stator and rotor windings
IEEE Transactions on Power Apparatus and Systems, 1975Two turbogenerators, the largest ever produced with direct water-cooling of both rotor and stator windings, were completed and tested early in 1974. Their losses and efficiency from test, together with temperatures in critical areas and cooling circuit behavior are described.

Core loss analysis on multi-pole-rotor doubly salient electro-magnetic wind generator
2009 World Non-Grid-Connected Wind Power and Energy Conference, 2009Wind 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-

The recent novel dc-biased sinusoidal current reluctance machines (dc-biased VRMs) adopt a doubly salient structure and concentrated windings, which is similar to that of switched reluctance machines (SRMs). The special point is that the phase current is in the form of an ac component superimposed with a dc component.
