Since conventional loading of induction motors is often expensive, the estimation of temperature rise by tools of mathematical modeling becomes increasingly important. Excepting for providing a more accurate representation of the problem, the proposed model can also reduce computing costs. The paper develops a two-dimensional transient thermal model in rectangular co-ordinates using finite element formulation and triangular shaped elements. A temperature-time method is employed to evaluate the distribution of loss in various parts of the machine. Using these loss distributions as an input for finite element analysis, more accurate temperature distributions can be obtained. The model is applied to the rotor of one squirrel cage TEFC machine of 7.5 kW during star-delta starting. The temperature distribution has been determined considering convection from the outer air gap surface.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121350299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In normal physiological condition, an RBC is circular in front view and biconcave in side view. Also it is 7.5 μm in diameter and 2 μm in thickness in terms of size. The normal morphology of an RBC undergoes some specific changes due to the consequence of different pathological abnormalities. One of such disease is Haemolytic Anaemia due to Enzymopathy (like G-6-P-D deficiency) where the RBCs take uneven edged `Bitten Apple' like shape. Here in this paper, correct identification of change in normal parameters of red blood cells in an anaemic blood sample has been presented using different image processing tools and techniques. Here the blood smear image is preprocessed by using Weiner filter and Sobel Edge detection method is applied to find the boundary of the corpuscles. Also the region selection is done by which a metric is formulated to determine abnormal shape of the corpuscles. The purpose of this paper is to highlight this medico-technical aspect only.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128919041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this, an unbalanced magnetic pull (UMP) will be setup between stator and rotor. This can cause bearing damage, rubbing of rotor with stator and may develop unwanted vibration and noise, which may results in premature failure of the motor. In this context, this paper presents the mathematical analysis of unbalanced magnetic pull due to air gap eccentricity in induction motor. Experimental investigations have been carried out to detect mixed airgap eccentricity fault by vibration signature analysis using Micro-Electro-Mechanical Systems (MEMS) accelerometer under different operating conditions. The spectral analysis of motor vibration has been carried out using radix-2 decimation in time Fast Fourier Transform algorithm (DIT-FFT). The presence of side band harmonic frequencies around fundamental component in the motor vibration signal spectrum indicates mixed eccentricity fault. The experimental results demonstrate that it is possible to identify the mixed airgap eccentricity fault by vibration signature analysis using MEMS accelerometer. A simple method has been proposed to find the fault severity in the motor under variable load conditions due to mixed air gap eccentricity.","PeriodicalId":290479,"journal":{"name":"2013 IEEE 1st International Conference on Condition Assessment Techniques in Electrical Systems (CATCON)","volume":"118 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115555832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
