Isogeometric analysis is employed for the space modeling method since it presents numerous advantages for describing complex geometrical shapes and computing electromagnetic fields distributions. A frequency-domain model is proposed to compute the nonlinear steady-state solution of the eddy currents damping due to the motion of a permanent magnet array. The resulting multiharmonic solver is more computationally efficient than its transient counterpart and is advantageously applied to design optimization.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128605697","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}

They are used in many different applications, for example, for pick-and-place robots, in packaging or sorting lines, or as gearbox actuators. A linear-rotary movement can be obtained with various combinations of linear and rotary machines, whereas depending on the specifications of the underlying application the most suitable actuator arrangement has to be identified. In order to simplify the selection of the appropriate actuator configuration, this paper first gives an overview of possible realization concepts of linear-rotary actuators, which are also suitable to implement magnetic bearings (MB). Afterwards, fundamental scaling laws concerning achievable axial forces and torques of linear and rotary machines with interior and exterior rotor arrangement are derived, enabling a qualitative comparison in order to figure out the most suitable actuator concept. In this context, it is important that the derivation also considers the machine-internal heat flow and the heat dissipation to the ambient, which finally leads to a maximum current density depending on the selected topology. All findings are verified by finite element method simulations. In order to show the applicability of the derived scaling laws, a design example is discussed.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125477995","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}

A low-power, passive holding force is obtained by including a biasing permanent magnet. Meanwhile, valve lifetime improvements require impact velocities close to soft-landing. As an alternative to position control, this paper proposes to integrate passive eddy current damping into the valve actuator. Alternative solutions to generate sufficient eddy currents are explored, including inserting conductive materials at locations of high magnetic field gradient, and short-circuiting the actuation coil. Impact velocities are reduced by 24.7% to 1.62m/s, while respecting the limited transition time.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116984386","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 aim of this study is to provide a framework for the optimisation of a piezoelectric actuator's design based on an accurate model of the actuator, allowing to make better use of these self-sensing methodologies. An actuator morphology and its corresponding design space are first presented, a set of objective functions to optimise is then presented, after which a first pass of analytical optimisation is performed. It is found that, in order to proceed with the study, a numerical approach is required. An algorithm providing a set of optimal solutions is proposed, and is then shown to provide points from the Pareto frontier of the optimisation problem. A single optimal solution is chosen based on a tradeoff on the Pareto frontier. The resulting actuator has a sensitivity of │ß│= 3.54 nC mN−1, presenting an approximate×20 increase in sensitivity over the CMBP03 bender designed by Noliac as well as a decrease in estimation error by a factor of 50.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"40 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":"129708283","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 the particular case of the Superconducting Magnetic Levitation (SML) method, based on the flux pinning property of high temperature superconductors (HTS) in the proximity of rare-earth permanent magnets, this issue is even more critical, as there is no control of the levitation gap, which changes according to the load. The proposed solution for the normal force issue consists of a Linear Induction Motor (LIM) optimized for urban SML vehicles. Analytical equations and finite element methods (FEM) are used. An innovative workbench for movement tests was developed to measure the parameters of interest.
