The cogging torque in dual-stator PMSMs can be calculated by the superposition of both cogging torque components from outer and inner stator parts neglecting the saturation effect. If out and inner parts have the same least common multiple of pole/slot number combination, both cogging torque components share the same harmonic contents. Therefore, the cogging torque harmonics from both components can be cancelling or additive, which depends on their phase angle difference. In addition to the relative position shift between inner and outer stators, this paper proposes more options using the canceling effect, such as relative position shift between inner/outer magnet poles, inner/outer slot number pairing, size pairing of inner/outer slot openings, and size pairing of inner/outer pole-arc to pole-pitch ratios. The investigation shows all these methods can effectively reduce the cogging torque. The analysis is verified by direct finite element results.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114442515","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 addition to a short settling time and a small setpoint deviation, a low current ripple is desired. The unavoidable ripple is caused by the switching principle of the used voltage-source inverters. The consideration of the ripple when determining the actuating variables differs between the established control approaches such as the field-oriented control (FOC), the finite-control-set (FCS), or the continuous-control-set (CCS)model predictive control (MPC). This also depends on whether a dedicated modulator is used or not. A CCS-MPC with integrated modulator which takes the principle of a pulse width modulation-like modulator (PWM)during optimization into account is presented. The setpoint deviation and the current ripple are the objectives of a optimization problem. Here, choosing an appropriate cost function is investigated such that the performance in steady state is comparable to that of a FOC and during transients to that of a MPC approach. The chosen cost function also defines the class of the optimization problem to be solved online in each controller cycle. Besides a simulative investigation, an experimental setup with a permanent magnet synchronous motor (PMSM)and qpOASES as solver for real-time optimizations was implemented.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113947618","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}

Due to limited inverter switching frequency, high-speed operation of a drive results in a low ratio between the switching frequency and the fundamental frequency of motor voltage. Such operating conditions have been recently identified as a source of errors in determining motor current feedback using the typical technique dedicated for microprocessor-based controllers. First, sampling the phase currents synchronously with the peaks of modulation carrier provides results of mean currents under an assumption of linear current changes in steady voltage intervals. This assumption is over-simplistic in high-speed drives. Second, transforming the phase currents into a rotating reference frame, required in Field Oriented Control (FOC), is carried out using discretized rotor angle. If rotor covers a substantial angular distance in the control cycle, such simplification distorts transformation results considered as mean values. This paper analyses the joint impact of both these oversimplifications on the errors of field-oriented current components derived in a microprocessor as a feedback to the control algorithm. The analysis was carried out for a highspeed PMSM drive operating at switching frequency of 5 kHz and maximal fundamental frequency of 350 Hz. Simulation results show that the considered oversimplifications lead to notable errors in digital processing of current feedback. The direct-axis current is affected by a notable offset, while the quadrature-axis current is supplemented with a high-frequency error component.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129811012","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}

This paper provides an overview of additive manufacturing (AM) approaches that can be used for constructing permanent magnet (PM) machines, with a specific focus on additively-manufactured iron core, winding, insulation, PM as well as cooling systems. Since there has only been a few attempts so far to explore AM in electrical machines (especially when it comes to fully additively-manufactured machines), the benefits and challenges of AM have not been comprehensively understood. In this regard, this paper offers a detailed comparison of multiple multi-material AM methods, showing not only the possibility of fully additively-manufactured PM machines but also the potential significant improvements in their mechanical, electromagnetic and thermal properties. The paper will provide a comprehensive discussion of opportunities and challenges of AM in the context of electrical machines.","PeriodicalId":378634,"journal":{"name":"2019 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133284370","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}
