A conventional IPMSM design prepared for the same purpose had a demerit that for absolute position estimation, saying that the rotor should initially stroke for 100° in the worst case. In order to reduce the initial stroke of the rotor, two new IPMSM designs featuring asymmetric winding and asymmetric rotor geometry are proposed and constructed as prototype motors. With the prototype motors, initial stroke of the rotor has been reduced to 30°. Moreover, basic characteristics of the motor such as torque ripples and harmonics of EMF have been also conspicuously improved. The overall performances of the proposed designs have been evaluated by rigorous finite element analysis and experimental test.","PeriodicalId":143142,"journal":{"name":"2014 IEEE 5th International Symposium on Sensorless Control for Electrical Drives","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130726319","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}

High frequency injection methods are very common in order to perform saliency tracking based self-sensing operation. Vanishing saliency for certain operating points or a change of the sign of the inductance difference, which needs to be known for the self-sensing algorithm, causes loss of stability of the self-sensing control method. This paper uses a simple, parameterized Finite-Element model in order to simulate the influence of geometric parameters and cutting edge deterioration. The simulations have shown that the cutting edge deterioration has only a slight influence on the saliency ratio of the differential inductances, although worst case conditions are assumed for the deterioration. This result is verified on a FE-model of a real PMSM. The most significant influence on the saliency ratio derives from the size of the tooth tip. For low ratios between stator yoke height and tooth width the area with vanishing magnetic anisotropy is increased. The area of magnetic anisotropy is increased with the width of the magnets, however the value of the anisotropy is decreased for large magnet widths.","PeriodicalId":143142,"journal":{"name":"2014 IEEE 5th International Symposium on Sensorless Control for Electrical Drives","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129403872","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 IPMSMs are controlled with a rotor position sensor or by a sensorless control method. Voltage-current phase difference control is one of the sensorless drives with low cost and simple structure. However, if the load varies depending on the rotor position the speed ripple occurs by torque fluctuation. This is because the voltage-current phase difference control is based on the V/f control and it uses neither position sensor nor speed estimation. In this paper, the amplitude of armature voltage is changed according to the load torque variation. Both simulation and experimental results show effectiveness of the proposed system.","PeriodicalId":143142,"journal":{"name":"2014 IEEE 5th International Symposium on Sensorless Control for Electrical Drives","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122346644","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}

High-performance control in ultra-high-speed region requires fast response time of control system and also short computation time. The DTC-based drive system has several advantages, including simple structure and sensorless drive, which are important for ultra-high-speed drives. In addition, short control period is achieved by using high-speed logic circuit. In this study, the DTC is implemented in a field programmable gate array (FPGA). Simulation and experiment are performed to discuss the effects of short control period in the steady-state. In particular, this paper shows control characteristics such as torque ripple and harmonics of the phase current under various control periods.","PeriodicalId":143142,"journal":{"name":"2014 IEEE 5th International Symposium on Sensorless Control for Electrical Drives","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129458607","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 case the information about the rotor position is included in the fundamental wave of the EMF and therefore the presence of harmonics will distort the estimation result. In order to compensate for harmonics information about their frequency is a prerequisite. In the case of wound rotor synchronous machines it is possible to obtain an accurate estimate of the speed by tracking the effect of the stator slots in the rotor current. For the rotor winding the stator slots represent a position dependent reluctance variation and therefore the rotor current will contain a harmonic component which is related to the rotor speed. The frequency of this harmonic component is tracked using an adaptive tracking filter and is then used to compensate for harmonics in the stator currents. The compensation is done by using adaptive resonant controllers. The suggested approach is verified experimentally by a highly utilized machine which is designed for automotive traction applications and features an extra-low voltage DC-link.","PeriodicalId":143142,"journal":{"name":"2014 IEEE 5th International Symposium on Sensorless Control for Electrical Drives","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133519405","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}
