This paper discusses a prototype setup of a sensorless controlled reluctance synchronous machine (RSM) equipped with sensorless controlled active magnetic bearings (AMB) for such target applications. The utilization of sensorless control methods to the AMB and also to the RSM results in a significant simplification of the system architecture and a hardware cost reduction. Additionally by using a three phase AMB topology the same three phase voltage source inverters can be used for the RSM as well as for the AMBs. In this work the focus is set to the sensorless control of the RSM. The basic principle of the two sensorless position detection methods applied to a magnetically levitated RSM prototype for high rotational speeds are investigated. Experiments in the sensorless operation are performed and by the results design criteria for RSM machines with big airgaps are identified, because this is required for the magnetic levitation. Thus, an improved machine design is introduced and simulation results are presented to confirm the improved machine design for such magnetically levitated high speed applications.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"53 1","pages":"916-921"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73553176","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 goal of this paper is to evaluate additional harmonic losses in relation to the machine's initial efficiency rating. However, due to the relatively small amount of additional loss, the main drawback when evaluating the effect of supply voltage distortion on the machines' overall efficiency is the measurement accuracy of the current methods. In order to validate the effect of motor efficiency rating in relation to supply voltage distortion, the use of the parameter \"harmonic active power\" is suggested. This new strategy is subsequently validated by measurements and compared to current methods such as the NEMA MG1, or the procedure according to the IEC60034-2-3. Although this strategy is only valid under certain constraints, this new method enables a fast and highly accurate measurement of the additional loss. Consequently, this parameter is used to validate the effect of efficiency rating of induction motors in relation to the additional loss related supply voltage distortion.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"20 1","pages":"1881-1887"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75408077","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 this paper three DIOWD topologies aiming for high speed and/or safety critical applications are evaluated. Their operation characteristics, VA ratings, efficiencies, harmonic distortion factors (HDF) are quantitatively compared using analytical methods. The utilization of dual inverters provides fault tolerant capabilities for the drive. However, the doubled number of devices increases the risk of single-point failure. Finally, the reliability of the drives is assessed by Markov chain technique. The results show that the DIOWD with two power supplies exhibits low HDF and high efficiency; it also offers better fault tolerant capability and enhanced reliability, thereby being more attractive for both high speed and high reliability applications. While the DIOWD with single power supply and the DIOWD with a power supply and a floating capacitor can be utilized for high speed drives with reduced dc link voltage.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"31 1","pages":"1029-1035"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85872097","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}

A lot of these harmonics are created due to the spatial positions as well as slot structure of stator and rotor and thus known as space harmonics. If the supply is imbalanced or the motor is fed from an inverter, which is the most likely case in industrial environment, even more harmonics are created in time domain. As unwanted as these harmonics may be, they have a good use for condition monitoring of the motor. The harmonics show a certain behavior for a healthy motor and deviations from those behavior may lead to detect a fault as it happens. Most of the existing electrical techniques of condition monitoring are based on the time harmonics analysis of the stator current and/or leakage flux. We propose to analyze the space harmonics of the main air gap electromagnetic flux along with the time domain analysis to detect faults. To this aim, we present a model to analyze the space harmonics of the main air gap flux of a healthy as well as an eccentric induction motor in this paper. We also propose a method to detect and differentiate among different types of eccentricity, i.e. static, dynamic and mixed eccentricity by analyzing the main air gap flux with respect to both stator and rotor. Our presented results show that the space harmonics analysis can be used to detect and differentiate between different types of eccentricity unambiguously.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"130 1 1","pages":"1466-1472"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81124561","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}
