The axial topology allows to develop high torque in low speed operation without the need of a gearbox, increasing the efficiency of the drive. This could represent a maj or advantage for the industry, in terms of the costs associated with its operation and reliability. The AFIM is analyzed by means of a multilayer model in Cartesian coordinates, where each layer represent a different region of the magnetic circuit. Poisson's and Laplace's equations are derived from Maxwell's equations and used to determine the induced currents of rotor, torque and efficiency. The proposed model considerer a power supply with voltage sources and the stator currents are calculated by means of the equivalent circuit which is previously determined by means of the multilayer model.","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114967381","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}

Removing the heat directly from where it is generated offers the most straightforward way for cooling in applications where the motors operate at elevated tangential stress during certain periods. This paper studies the feasibility of the direct liquid cooling using a radial flux permanent magnet motor as an example. The easiest way to provide experimental data was to install a directly liquid cooled motor is a test bus with which typical bus load cycles were tested.","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115324287","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}

LAs usually incorporate mechanical springs realizing a resonant system which handles the alternating kinetic energy flow stored in the moving mass. In practice, however, parameter inaccuracies and drifts in the operating frequency result in off-resonance operation causing stroke and power drops. This paper presents an adaptive tuning strategy for the electronic stiffness in order to restore resonance and maximum power flow. The algorithm is based on a low-frequency amplitude perturbation of the current component in phase with the stroke. The response of the LA to this low-frequency parametric excitation allows the detection of out-of-resonance conditions and the correction of the current amplitude in phase with stroke in order to restore resonance. The paper discusses an approximated mathematical analysis of the control algorithm and presents validation via simulations.","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115746925","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 applicable zone of the INC covers the medium-low torque zone of the torque-speed plane. In this zone, the INC can increase the global efficiency up to 22% which corresponds to a loss reduction. However, the SRM in the electric vehicle operates only in certain torque-speed zones which correspond to various driving scenarios. For this reason, the INC is validated with a particular electric vehicle motorized by a traction scaled SRM on the Worldwide harmonized Light vehicles Test Cycle (WLTC). The simulation results show that the INC reduces the consumed energy up to 4.6% on the WTLC.","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121111492","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 wind generator systems are described and the methods used in the design optimisation process to generate sufficient performance are discussed. The main comparisons between the generators are the active mass and PM mass.

In this paper, V old-Kalman filtering order tracking (VKF-OT) and dynamic Bayesian network (DBN) are used to investigate the application of torque ripple in real-time PM flux monitoring. Firstly, a torque ripple model of PMSM considering electromagnetic noise is proposed, and the torque variation is studied. In this model, the torque is analyzed and processed by wavelet transform to eliminate the effects of the electromagnetic disturbances. Secondly, VKF-OT is introduced to track the order of torque ripple of PMSM running in unsteady state. Therefore, torque ripple characteristics can be used as a feature to reflect changes in PM flux linkage. Thirdly, this method is feasible for PMSM by applying DBN to the training data to estimate the flux linkage during motor operation. The proposed flux monitoring method is validated on a laboratory PMSM. The results demonstrate that this method can monitor the flux variation over a wide speed range at different load levels.","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125335323","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 study moves from the traditional way adopted to measure them, that is by conventional no load tests; the experimental procedure here proposed is described in details, highlighting the advantages with respect to the previous method. A cheaper test bench is needed, as the gearbox is avoided, and a stepper motor in place of a DC motor is adopted to move the system. The procedure has been tested on two identical machine structures, but with different stator materials (traditional laminated steel and Soft Magnetic Composite material); a comparison with the results obtained with traditional no load tests has been performed to validate the proposed procedure. The novel method is more accurate in the detection of the cogging torque, even if requires a measurement time slightly longer (about 30 minutes of duration).","PeriodicalId":292261,"journal":{"name":"2018 XIII International Conference on Electrical Machines (ICEM)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115068867","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}
