• ### Experimental assessment of end region cooling arrangements in induction motor endwindings

Publication Year: 2011, Page(s):203 - 209
Cited by:  Papers (6)
| |PDF (662 KB)

In this study the impact of different end region cooling arrangements on the endwinding heat transfer is analysed and discussed. An experimental approach to solving the problem has been adopted; two special prototypes have been built and a test bench has been assembled. Open drip proof ODP and total enclosed fan-cooled TEFC frames have been taken into account. In addition, the cooling effect o... View full abstract»

• ### Flux linkage determination of the switched reluctance motor from measurable quantities at steady-state operations

Publication Year: 2011, Page(s):210 - 216
Cited by:  Papers (6)
| |PDF (530 KB)

A new method to obtain flux linkage characteristics of the switched reluctance motor (SRM) is presented. Unlike most of the previously reported methods, the proposed method avoids the usage of a clamping device or a search coil so that it is sometimes more applicable for practical implementations. The proposed method calculates flux linkage with the measured rotor position, phase voltage and phase... View full abstract»

• ### Design and control of an electromagnetic fast tool servo with high bandwidth

Publication Year: 2011, Page(s):217 - 223
Cited by:  Papers (1)
| |PDF (480 KB)

This study presents the design, control and implementation of a high bandwidth electromagnetic fast tool servo (FTS) that has the potential for use in diamond-turning of non-rotationally symmetric surfaces. The FTS is driven by a normal stress electromagnetic fast linear actuator and a custom current amplifier. It is controlled by a host-target real-time computer system. To achieve the high tracki...

• ### Flux regulation ability of a hybrid excitation doubly salient machine

Publication Year: 2011, Page(s):224 - 229
Cited by:  Papers (11)
| |PDF (459 KB)

In this study, hybrid excitation doubly salient machines (HEDSMs) with parallel excitation structures are introduced. The three types of main poles in the HEDSMs are described and researched, respectively. A 30/20-pole HEDSM is analysed by the magnetic circuit means. Regulation performance of the air-gap fluxes of different main poles is presented. The expression of the total air-gap flux shows th... View full abstract»

• ### Fuzzy information granulated particle swarm optimisation-support vector machine regression for the trend forecasting of dissolved gases in oil-filled transformers

Publication Year: 2011, Page(s):230 - 237
Cited by:  Papers (6)
| |PDF (297 KB)

In order to achieve accurate trend forecasting of gas contents in oil-immersed transformers, a fuzzy information granulated particle swarm optimisation-support vector machine (PSO-SVM) regression model is proposed in this study. The fuzzy information granulation approach is implemented to transform the original gas data into a sequence of granules, gaining more general view at the data that retain... View full abstract»

• ### Parameter identification of transformer detailed model based on chaos optimisation algorithm

Publication Year: 2011, Page(s):238 - 246
Cited by:  Papers (14)
| |PDF (470 KB)

The R-L-C-M model of a power transformer is obtained from geometrical structure and is extremely appropriate for studying transient phenomena in a transformer and detecting mechanical faults. The precision of this model depends strongly on the precision of its parameters. The accuracy of these parameters that are calculated by analytical formulae is limited because of different reasons. In this st... View full abstract»

• ### Analysis and control of self-excited induction generator-converter systems for battery charging applications

Publication Year: 2011, Page(s):247 - 257
Cited by:  Papers (21)
| |PDF (1167 KB)

A method has been developed for the analysis of operation of self-excited induction generators (SEIGs) supplying battery charging loads through three-phase semi-converters by representing the battery circuit as equivalent resistance and reactance in the equivalent circuit of these generators. Such equivalent values are functions of the dc charging voltage and current and the control angle set in t... View full abstract»
