Recent advancements in magnetic materials and semiconductor devices are enabling a new class of electric motors which utilize ultra high rotational speeds (100,000+ RPM) to increase power density. The technology is limited by shortcomings related to motor bearings, primarily insufficient lifetime and rotor dynamics that limit the speed-power capability of the electric machine. This paper investigates the design of a magnetically levitated, ultra-high speed motor based around a bearingless permanent magnet motor topology to solve these challenges. The design targets a speed-power capability of 160,000 RPM and 5.5 kW for a hydrogen fuel cell compressor. This rating is amongst the highest speed-power designs that utilize conventional bearings and would expand the limits of speed-power rating of a bearingless motor. A detailed multi-physics modeling framework is developed and coupled to a multi-objective optimization algorithm to explore the design space. An optimal design is proposed and investigated for prototype fabrication. Experimental validation of the modeling framework is provided with low speed and stationary test results.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123022392","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 input inductor is adopted in the first stage of the converter to suppress the current spikes caused by switched capacitor. At the same time, when the input inductance and the switching capacitance are less than or equal to the theoretical values, the first stage can realize zero current switching (ZCS).To achieve the ZCS of other switching devices, an auxiliary resonant circuit is added in the second stage of the converter, and it is necessary to ensure that the switching on time in advance of the auxiliary switch is within the theoretical range. This converter has the features of high step-down ratio, soft switching on/off, and low device stress. After the working principle and the characteristics of the converter are introduced in detail, the feasibility of the proposed topology is verified by simulation and experimental results.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117238261","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}

Combining synchronized space vector PWM schemes with the model predictive flux control, a control strategy is developed that does not require phase compensation of the voltage reference and smooth transition between different PWM modes is achieved.

The thermal stress of the permanent magnet synchronous motor (PMSM) is the main factor leading to such malfunction. It is critical to monitor the rotor temperature by tracking the permanent flux. Based on the characteristic that the magnitude of the magnet flux linkage decreases as the temperature increases with a linear relationship, a novel non-invasive method is proposed to estimate the temperature of permanent magnet (PM) in PMSM. To solve the rank-deficient problem of the state estimation, the proposed method utilizes two Extended Kalman filters to estimate the magnet flux linkage and stator inductances information respectively. Meanwhile, the estimation results of flux and inductances message are used as known quantities in the other estimation algorithm, which forms an iterative algorithm process. When the updating of flux and inductances are executed simultaneously, the influence of magnetic saturation is compensated automatically. Simulation and experimental tests are implemented to verify the accuracy and feasibility of the proposed method. With errors less than 4 °C, within an acceptable range, the capability of providing non-invasive monitoring on the rotor temperature with high precision is proven.","PeriodicalId":433712,"journal":{"name":"2020 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129850425","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}
