This method covers the domains of electromagnetics, the mechanical strength, thermal behavior and the magnetic noise. It is shown that the proposed novel asymmetric design with a circular flux barrier in combination with an asymmetric pole offset is fulfilling the requirements according to performance and torque ripple. A fatigue strength rotor mechanic concept is included. A hybrid cooling concept consisting of a water jacket cooled stator and air cooled rotor ensures the needed continuous power. Unacceptable noise levels are excluded by investigating the equivalent radiated power (ERP) level due to radial forces in the air gap. Finally, the multi-physical workflow resulted in a fully developed component with a high degree of maturity.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132880792","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 simulation results show that the H-PMASynRM having the first layer made of NdFeB, the second layer made of ferrite, and the third layer made of a combination of ferrite and NdFeB, can exhibit the same maximum torque of 220 Nm with $12 lower cost, 1-3% higher efficiency at speed above 8,000 rpm, 6.8% lower peak power factor, and only 17% lower torque density compared to the NdFeB-based V-type PMSM that is used in Toyota Prius 2010.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134132471","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}

However, the most methods select voltage vectors based on enumeration and cost function, so it greatly increases control system complexity. In order to reduce control complexity and further improve steady-state control performance, a predictive current duty cycle control based on the reference voltage (PCDCC-RV) is proposed in this paper. The applied voltage vector is determined based on the location of the synthesized reference voltage, so the complicated enumeration process is cancelled. In addition, the control duty cycle is calculated based on the principle of minimum error between the selected vector and reference voltage. Compared with the traditional method, the proposed method of voltage vector selection and duty cycle calculation are more convenient, and the better control performance is obtained. Finally, simulation results prove its effectiveness.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134453009","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}

Typically, these PMSGs are coupled with fully rated active rectifiers to process and deliver power to the main grid. However, the limited-speed nature of a wind turbine creates an opportunity to reduce the amount of active rectification required, which in turn would reduce the cost of the drive and improve system reliability. This paper presents a design and optimization process of a direct-drive PMSG coupled to an integrated generator-rectifier system. In order to make the hybrid architecture possible, a multi-port generator is designed with multiple diode rectifiers and a single active rectifier. This paper describes a process for a 10 MW generator-drive optimization under the proposed architecture with two different implementation methods. These implementations are compared using optimal Pareto front from a system-level efficiency-weight perspective.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132517941","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}

Dysprosium (Dy) is one of the heavy rare-earth elements used in higher Permanent Magnet (PM) grades and its inclusion is critical to eliminate/minimize the risk of permanent demagnetization. On the other hand, Dy is one of the key elements that are subject to price volatility as well as sustainability concerns. Therefore, this paper aims to propose an IPM machine design for traction applications based on Nissan Leaf 2012 electric motor using a blend of magnet types that eliminate the use of Dy (can be thought of as hybrid magnets) to reduce the overall PM cost while maintaining comparable electromagnetic performance. Most importantly, this paper's objective is to provide a topology for the transportation sector using PM materials that addresses sustainability concerns. This paper will present the electromagnetic performance evaluation of the proposed design using Two-Dimensional Finite Element Analysis (2D-FEA). Comparison of key performance metrics including torque vs. current angle, efficiency map, risk of demagnetization, and comprehensive comparison to the baseline design will also be presented. In addition, rotor mechanical analysis as well as cost analysis are included.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127815234","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}

Stable levitation cannot be achieved through a static passive magnetic bearing system, as indicated by Earnshaw's Theorem. Solutions using active magnetic bearings have been presented which achieve stable levitation, but induce losses in the current used to actively stabilize one or more degrees of freedom. To overcome these losses while retaining stable operation a fully passive architecture can be created utilizing superconducting magnetic bearings. This paper will review the key passive magnetic and superconducting technologies, their design and optimizations methods for different topologies, and existing work done to combine both into a functional stable system.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126919515","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}

It has been proved that by adjusting the distribution of stator auxiliary teeth, the flux modulation effect and no-load back EMF of DP-STVMs can be enhanced. However, this irregular structure also changes the periodicity and increases the amplitude of cogging torque. To investigate the source of cogging torque in DP-STVMs, an analytical method based on airgap fields and Maxwell stress tenser method is used, which can easily present the contribution of each airgap field component to the cogging torque. Based on the analysis, novel cogging torque reduction methods are proposed in this paper. Compared to regular rotor skewing method, the proposed methods can achieve better suppression effect on cogging torque and less reduction on noload back EMF.","PeriodicalId":106489,"journal":{"name":"2021 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"330 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116355571","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}
