The paper concentrates on windings printed on PCB. This kind of winding offers opportunities to significantly improve motors' performance, although it is more subject to eddy current losses than wire windings. Therefore, considering the harmonics contained in the airgap magnetic field, the work especially focus on the development of a 2D FEM model able to estimate these eddy currents in the copper tracks. The objective is to evaluate the eddy current harmonics and to adapt the winding shape and the motor dimensions, accordingly. The final aim of this work is therefore to propose full motor optimizations for various operating points and to observe the evolution of its optimal configuration.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"76 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":"124918096","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 focus lies on minimizing the power loss to achieve highest possible efficiency. First analytical considerations reveal the potential of designing electrical machines for periodic, accelerated motion. It shows the influence of the machine size on the power losses due to the dependence of machine force as well as moving mass on this parameter. Based on these findings, a simulation model was created with which a linear machine can be optimized for a specific motion and load cycle. The simulation consist of a stationary and a time dependent finite element analysis of the linear machine in conjunction with an operational model that includes a given movement cycle. It was used to design a flat type linear machine for a free piston linear generator. The simulation results validate the analytical calculations and illustrate the differences to conventional design approaches for linear machines.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"30 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":"126668280","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 a brand new Halbach array using cylinder-shaped permanent magnets, by synchronized rotation in the same direction with of all magnets, the slide of the magnetic field distribution has been confirmed by quasi static measurement. Recently, by an actual test model of the cylinder-shaped permanent magnet type linear Halbach array with synchronized rotation mechanism, continuous slide of the magnetic field distribution is confirmed. The synchronous rotation mechanism of this test model is a mechanical drive by meshing gears. The latest measurement result shows that the characteristic of the magnetic field slide is also reflected by the backlash of the gear and the magnetic interaction of the arranged permanent magnets. On the other hand, in preliminary experiments using bulk high temperature superconductor, it is also possible to observe non-contact move in synchronization with slide of the magnetic field.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132605975","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}

Nowadays, robotics technology is developing rapidly, and piezoelectric motors also usher in its application opportunities. Compared with vertical motors, horizontal motors are easy to be arranged in the driving module, but their power is often too small to be noticed. Horizontal plate motor meets the need of cylindrical drive in structure and has good application value. This paper first describes the horizontal motor developed by the author, and analyses the disadvantages of L1B4 motor, such as low output thrust, easy separation of two-phase resonance frequencies and poor bi-direction performance. Finally, experiments are done to show that the above shortcomings have been improved and overcome, and the performance has been upgraded.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","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":"133957943","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}
