Motor and generator applications require the machines to produce a smooth torque with very low cogging torque components. This paper presents a simplified energy approach for a model of the machine with PM located on the rotor surface. Briefly, analytical co-energy formulas are applied in order to determine the cogging torque harmonics and show methods of their reduction. Additionally, the analysis of cogging torque for machines with the poles composed of segmented PM are presented.","PeriodicalId":286682,"journal":{"name":"2017 International Symposium on Electrical Machines (SME)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115716620","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 stator windings are supplied by two independent power converters. During normal operation, the machine operates in dual-channel operation mode whereas after fault of one channel, further operation of the machine can be continued in so-called single-channel operation mode. Static flux characteristics i.e. dependencies of self-fluxes and mutual fluxes in the function of phase current and rotor position for particular phases of each channel of 12/8 DCBLDC machine were determined based on 2D FEM calculations. Determined flux characteristics are necessary for estimation of electromagnetic torque of DCBLDC motor under dual-channel operation mode and also under single-channel operation mode.","PeriodicalId":286682,"journal":{"name":"2017 International Symposium on Electrical Machines (SME)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126613484","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}

Their intensity is usually small compared to the intensity inside the motor due to a closed magnetic circuit. However, there are other open motor constructions where the influence of stray magnetic fields cannot be neglected. This paper analyses a particular case of influence of stray magnetic fields of a motor in the multi-motor assembly. Three bipolar two-phase stepping motors with permanent magnets are arranged close to each other. The rotor position of each motor is affected by stray magnetic fields of nearby motors. Therefore the magnetic shielding is placed between rotors to reduce the position shift of the rotor due to the rotation of neighbouring rotors. The dimensions, namely diameter and thickness, of the shielding element are design variables of optimization. The objective function is a sum of squared deviations of a rotor position from each desired step angle and should be minimized. The value range of diameter and thickness is restricted by motor dimensions. Step angles are calculated by Finite element method. For this purpose, a MAXWELL ANSYS 3D model of multi-motor assembly was built, and a dynamic rotor angle response was simulated. The steady state angle for each half step is retrieved from simulation and is used for the objective function evaluation. Response surface of the objective function, as well as optimal dimensions of the magnetic shield subject to optimization constrains, is showed.","PeriodicalId":286682,"journal":{"name":"2017 International Symposium on Electrical Machines (SME)","volume":"24 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132200576","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}

Both generators use the same stator. The first generator has the rotor in the form of a steel pipe with segment magnets glued, on it. In the second generator magnets are placed inside the rotor that is composed of plates. The generator stator has 36 slots holding a three-phase eight-pole winding. In order to minimize cogging torque the skew of three magnets bonded on the surface is applied in the first rotor. The second rotor is divided into 6 segments twisted with respect to one another by 2 degrees. The housings and shield bearings of a standard three-phase motor are used to construct the generators. The paper presents selected test results including the influence of output voltages upon rotational speeds, the influence of the output voltages upon the load current, the measurements of cogging torque and the results of generator warm-up.
