Focus is placed on the Rhodes electric piano, which gained popularity in 1960s and is still highly valued among jazz, soul and popular musicians. In most existing studies, the induced electromotive force (EMF) in the pickup of musical instrument is calculated using simplified methods in which the vibrator is modeled as a point without volume. In this study, detailed finite element analyses are performed to calculate the EMF in the pickup system as well as the estimation of the effect of the eddy current in the system. A solution procedure to obtain the EMF for a class of problems in which movement of the vibrator of the musical instrument is described by finite degrees of freedom is proposed. Sound generated based on the pickup model is evaluated as well. Simplified calculation methods of the existing studies are also reviewed and a modification is proposed to improve the accuracy.","PeriodicalId":317315,"journal":{"name":"2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115371768","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 method is based on two complementary steps namely the forward and inverse models. The forward model is used to generate the TDR response using RLCG circuit model and Finite-Difference Time-Domaine (FDTD) method, and to create the datasets. The inverse model allows to detect, localize and characterize the faults from the time response of the faulty network by using Random Forest (RF) technique. Two types of RF models have been used in the diagnosis procedure: RF classifiers and RF regression models. Numerical and experimental investigations have been performed in order to test the performances and the feasibility of the proposed approach.","PeriodicalId":317315,"journal":{"name":"2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121655104","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}

Especially, design optimization methods such as the level-set method with FEA result in large computational effort to find better solution. In this paper, we propose a novel method of precisely and quickly reproducing the conventional optimization steps by means of Convolutional Neural Network (CNN) and Long Short-term Memory (LSTM). The developed method enables us to implement high speed search of solution, which means the possibility of effective optimization with various initial conditions for better solution. Finally, we evaluate calculation time and computational accuracy of the proposed method by using a magnetic circuit design model.","PeriodicalId":317315,"journal":{"name":"2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134024185","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 optimal designs of the machines, intended for small wind turbines, use multidisciplinary optimization models and a deterministic algorithm. As high power density is desired, only flux concentration topologies that allow high values of magnetic induction in the air gap were proposed, including inner and outer rotor machines. For the inner rotor conventional machines, both an integer and a fractional number of slots per pole per phase were proposed. A conventional and a vernier radial flux machine, both of them with outer rotor and fractional number of slots per pole per phase, were also considered. After validation of each optimal design by a finite element analysis software, the more convenient number of pole for each topology was identified, observing that the vernier machine presented the lowest torque ripple, the highest power density and the lowest active material cost among the four topologies of PMSGs.","PeriodicalId":317315,"journal":{"name":"2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132371318","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 magnetic dissipations are experimentally investigated focusing on their nonlinearity with respect to frequency and amplitude of oscillations. The system exhibits two types of nonlinearities: one proper of the mechanical system and one of due to the magnetic coupling. The availability of an electromagnetic-motional model allows for the separation of these two effects. A frequency domain model to describe the magneto-mechanical interaction under harmonic excitation is developed by means of a partial element equivalent circuit of the conductive parts. The restitution magnetic force model is then introduced in the numerical model of the system. Results obtained by simulations are validated versus experimental measurements on the three degrees of freedom structure.","PeriodicalId":317315,"journal":{"name":"2019 22nd International Conference on the Computation of Electromagnetic Fields (COMPUMAG)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132388214","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}
