Some variations in induction motors such as torque load anomalies must be considered in order to reliably detect stator faults. This paper presents robust artificial intelligence (AI) techniques for interturn short circuit (ITSC) fault detection of stator in three phase induction motors. In this work, the focus is first on the application of artificial neural networks and then fuzzy logic systems to reduce significantly the effect of load variations on fault detection procedure. The proposed ANN methodology has the merit to detect and locate ITSC fault, while the Fuzzy approach is capable of detecting and diagnosing the severity of ITSC fault. The simulation and experimental results are also given to verify the efficiency of both approaches under ITSC fault and load change.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"154 1","pages":"1446-1451"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79877838","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 absence of magnets means that synchronous reluctance machines are not susceptible to price variability and sustainability of rare-earth materials. Also, there are no concerns about demagnetization or uncontrolled generation mode. However, the challenge of achieving a good constant power to speed ratio is dependent on the mechanical aspects of the design. Conventional synchronous reluctance designs perform poorly compared to the permanent magnet machines due the presence of bridges and/or center posts in absence of the magnets to help saturate these regions. In this case, the challenge of rotor mechanical retention is addressed with the help of a sleeve on the rotor to reduce the need for bridges and/or center posts. Design optimization including the mechanical aspects of the sleeve is presented in this paper. The final design with a sleeve will be shown to be superior to a conventional design in terms of power density, rotor losses, saliency and torque ripple.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"25 1","pages":"195-201"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81744966","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}

Axial peg style refers to the geometry of the machine. Interdigitated pegs (cylinders) come into, and out of, radial alignment as the machine rotates causing variable capacitance between the stator and rotor. A prototype with peak torque of 0.9 N-m and gap field strength of 14 kV/mm was constructed. The specific torque density of the machine is 0.126 N-m/kg, comparable to fractional horsepower NEMA class induction machines. This was achieved by filling the machine with a dielectric fluid whose relative permittivity is 7.1, rather than ultra-high vacuum typically employed in canonical macro scale electrostatic machine designs. Selected experimental measurements presented include angular capacitance, stall torque, average torque and losses under stall conditions.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"2 1","pages":"604-610"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88117326","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}

An improved dynamic machine model incorporating the dependence of inductances on magnetizing currents has been developed. Through the combination of experimental test methods conducted on the inverter connected LSIPMSM under varied operating conditions and IPSO algorithm, parameters such as stator and magnetizing inductances and damper parameters have been identified for all conditions. Though conducted on LSIPMSM, the modeling and identification procedures presented in this paper are also applicable to IPMSM and surface magnet PSM with simplified variations.

The new topology is based on the conventional voltage-fed inverter, but includes an additional source such as a capacitor or a battery, and requires connection to the BLDCM neutral. The objective of the proposed control strategy is to control the otherwise unregulated voltage across the additional source, while maintaining commanded speed or torque. Three variations of the control strategy are presented. A detailed simulation model is used to evaluate the performance of the considered converter with proposed control strategy, and compare it to a conventional voltage-fed inverter BLDCM drive. Performance measures include torque per unit current, copper losses per unit current, inverter losses, and efficiency. It is also shown that exact torque and speed control can be exercised at up to twice the rated speed. Simulation results for operation at twice the rated speed with the torque controlled to half the rated value are provided to demonstrate that. This is a major advantage over the conventional BLDCM drive, where speed and torque are usually uncontrolled above rated speed. In addition, the drive is shown to deliver rated power (at rated speed) with only half the dc link voltage.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1 1","pages":"904-909"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83672812","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}
