In order to use the method of high-frequency pulsating vector voltage carrier signal injection-based sensorless control techniques, the machine saliency is essential. However, the machine saliency behavior is complicated in real SFPM machines since it is dependent on the load condition. Furthermore, there may exhibit multiple saliencies due to the non-sinusoidal spatial distribution of machine reluctance. Saliency ratio and feasible region are usually used to describe the machine saliency level. It varies with fundamental excitation due to the magnetic saturation. Two simplified experimental procedures are employed for practical testing of saliency investigation in this paper, which could easily measure and obtain the machine saliency information without any knowledge of machine parameters. The experimental results show that the prototype machine has both primary and secondary (multiple saliencies) saliencies. The performance of rotor position estimation is implemented based on sensorless control at low and zero motor speed.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"71 1","pages":"2238-2244"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84996896","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}

Moreover, use of infrared thermography data to diagnose rotor bar failures is preliminarily studied. In the paper, a 1.1 kW induction motor is tested. Thermography images of the chassis temperature are captured at each second during the whole startup transient, from standstill till steady-state, by using an infrared camera connected to a laptop computer fitted with an acquisition and analysis program. A model based on the calculation of the heat losses by convection and radiation through the frame of the machine is developed. It uses the geometrical dimensions as well as temperature values obtained from the thermography images. The developed model enables studying any motor configuration and operating conditions by just varying thermal and geometry parameters. Finally, a preliminary study relying on the possible use of Thermography data for diagnosis of rotor failures is carried out. Experimental data corresponding to a healthy machine and a machine with broken bars are analysed and compared. This methodology will be the baseline for further complex failure diagnosis in electric motors.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"68 1","pages":"525-531"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81848008","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 control algorithm needs a good motor state variables estimation, such as a proper flux orientation, to assure full torque and power performances. Usually observers or estimators are adopted, but good results are strongly parameters dependent. In the induction machine control one of the most important parameter is the rotor resistance, that is temperature-dependent and therefore time-varying. The paper shows and compares three different Model Reference Adaptive System (MRAS) rotor resistance estimation methods, based on total active power, reactive power and motor torque. The algorithms have been studied by means of a rotor resistance uncertain of estimation based sensitivity analysis for different load and speed operating conditions. A simulation analysis has been proposed since the algorithm has been defined in order to operate under dynamic conditions, the typical situation during an electric vehicle drive cycle. A simple non linear variable structure MRAS has been adopted for assuring a good rotor resistance estimation convergence. Full theoretical analysis are reported for all the proposed methods.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"50 1","pages":"823-829"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80577155","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}
