MSM technology is being considered increasingly for various actuator applications due to its potential advantages such as fast response times. A further advantage is the possibility to actuate not only magnetically but also thermally; which enables replacing a thermal and a magnetic actuator by a single MSM actuator. This is particularly beneficial in miniature circuit breakers, where currently a thermal actuator is used for overload and a magnetic actuator for short circuit protection. This paper presents a linear MSM actuator comprising a single-turn coil, a magnetic core and an MSM element block. The magnetic and mechanical aspects of the design are explained, and two actuator demonstrators are shown. Experimental results are given to validate the design.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","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":"116016269","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}

Most system consists of the levitation (and guidance) section and the thrust one. Therefore, in this research, levitation and thrust are performed in the same system. The experimental device designed by the three-dimensional FEM analysis has been developed. In the conventional system, difference of the attractive force between the ends of the U-shaped iron core generates the inclination of the carrier. By changing the excitation method on the primary of the linear stepper motor, the inclination of the carrier is reduced. The carrier is levitated around the target levitation gap in the levitation experiment using the new excitation method.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"185 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":"122768269","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}

This paper presents a speed increasing plan by adopting 3000V DC power supply instead of original 1500V DC, under such condition, the output voltage of inverter could be doubled and maximum speed of single-sided linear induction motor (SLIM) would rise massively.

The control of a linear generator is usually synchronized with instantaneous speed which sets a reference for optimal current - usually in phase with speed. Measuring speed, however, is often challenging because the linear alternator is located in a sealed pressurized vessel or operates in a harsh environment. This paper proposes a simple sensorless control based on a linear observer which estimates instantaneous velocity of the plunger to be used as a phase reference to synchronise the control. The performance and sensitivity of the proposed observer is studied and verified by means of both simulation and experiment. For the particular example the estimated position (from estimated speed integration) is lagging 6.8° towards the measured position, and their amplitudes are different by less then 1%.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"02 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":"128975103","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}

By employing surrogate assisted indirect optimization methods, the task at hand is accelerated. However, for large design parameters vector, initial finite element analysis samples required to generate those surrogate models is high. Coupled with the fact, that use of three dimensional FEM is indispensable for a transverse flux machine, optimal design demands high computational resources and time. To reduce design time without loss of accuracy, this paper proposes to exploit the correlation between a low fidelity (Equivalent 2D-FEM) and a high fidelity (3D-FEM) model and generate a co-kriging based multi-fidelity surrogate which is then employed for optimization. The method is applied to a hybrid transverse flux PMLSM. Compared to conventional surrogate based methods, considerable reduction in design time is achieved.","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":"129805299","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}

It allows compact solutions with a low mover mass, what is especially for oscillatory direct drives a main issue. Thus, in contrast to common air gap winding solutions slotted designs are favored. With tubular linear designs, the resulting radial forces ideally cancel, but a significant destabilizing radial stiffness remains. In the presence of an inevitable eccentricity of the mover, the unbalanced magnetic pull adds up an extra load on the bearings, limits efficiency and reduces the bearing lifetime. This is of special interest when bush bearings are applied. This paper proposes a concept that actively compensates for the resulting radial forces. Next to the winding system for thrust generation, an additional independent set of windings is installed to cancel radial forces. A systematic design of a proper compensation winding system is outlined and its advantages and limits are discussed. The proposed compensation has the potential to significantly reduce wear and thus improve efficiency and bearing lifetime.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","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":"123112526","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}
