The (1-2s)fo component arises as the main effect of the cage asymmetry whereas the (1+2s)fo component is a secondary effect. It is commonly known, that it arises due to speed ripples, which are generated by alternating component of electromagnetic torque in a motor with faulty cage. This paper shows that magnetic saturation of a main magnetic circuit also generates the (1+2s)fo component in stator currents. A special mathematical model accounting for saturation is used to prove this thesis. Results of quantitative analysis of an influence of inertia and saturation on the (1+2s)fo component is shown.","PeriodicalId":185737,"journal":{"name":"2007 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125568000","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}

The design and verification of these methods imply the use of complex mathematical models that allow the study of the influence produced by the machine operating conditions over the diagnosis procedure. The present paper describes a model for asynchronous motors based on a network of magnetically coupled reluctances. The aim of this model is its application to the study of the typical failures of this type of machine i. e. rotor asymmetries, air gap eccentricity, operation with an open phase etc. The dynamic properties of the model allow the simulation of the spatial evolution of all the motor variables, without neglecting complex phenomena such as magnetic saturation. Time domain analysis of air gap torque, as well as the calculation of current harmonic components is also possible. This initial study is aimed to check the accuracy and computation economy of the model. To do this, the model will be used to analyse a new diagnosis method for rotor fault detection. Simulations of healthy and faulty motors will be presented and the evolution of the machines main electrical and mechanical variables will be obtained.","PeriodicalId":185737,"journal":{"name":"2007 IEEE International Symposium on Diagnostics for Electric Machines, Power Electronics and Drives","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128262800","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}

The system under analysis contains a single-phase active rectifier in the front end, a MPPF capacitor in the DC link, and an inverter which supplies a three-phase induction motor with indirect rotor field oriented control (IRFOC).

Referenced stator flux vector is predicted and after comparison with actual stator flux vector the flux error is defined. This error is delivered to the SVM, which is Flux Vector Modulation. Presented method allows to achieve good dynamic performance, as good as DTC-SVM, in constant torque region, constant power region and also in constant slip frequency region.
