In this paper, an 8-module Halbach array with unequal thickness is proposed to improve the magnetic density of Halbach Array and reduce harmonic content.

The structural feature of Halbach arrangement using cylinder-shaped PM is that the arranged permanent magnets are not in contact with each other. In case of the dimensions and magnetic properties of the cylinder-shaped PM are identical, the characteristic of the magnetic field of the novel linear Halbach array depends on the clearance of the arrayed cylinder-shaped PMs. Furthermore, since this model can configure not only the typical 90-degree rotating arrangement but also 45-degree and 60-degree rotating arrangements, the characteristics of the magnetic field due to these parameters are also of interest. In this paper, we show some complicated magnetic field characteristics and features in a 45- and 60-degree rotating arrangement model compared to the magnetic characteristics of a typical 90-degree arrangement in a flat model of a cylinder-shaped PM linear Halbach array. On these simulation results, from the viewpoint of non-contacting magnetic suspension due to the pinning effect of the flux of bulk HTS, we consider a feature of the magnetic field formation depending on the magnetic pole rotational angle arrangement.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"94 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":"126239004","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 this work, the Brinson model is further adapted so as to obtain an analytical model of a bias-spring shape memory alloy (SMA) actuator which consists of a SMA attached in series to a spring. This type of SMA actuator allows for the SMA to be cyclically actuated by heating and cooling. The dimensioning of bias-spring that is attached to the SMA is crucial for the actuating of the system. The adapted model presented in this work allowed for the analysis of the various design parameters when creating such an actuator while also allowing for an optimal dimensioning of the spring system so as to maximise the stroke of the actuator when activated.","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":"114148749","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 authors study spherical motors driven by magnetic forces to rotate the rotor and developed a technique, what we call Torque Map Control, to drive spherical motors referring the data prepared beforehand of working torques to the rotor in various relative spatial relations between the rotor and an electro-magnet installed on the stator when a unit current is given to the electro-magnet. For the control technique, it is necessary to measure the posture of the rotor that is presented by the rotation axis and angle from the base spatial relation between the rotor and the stator. This study developed a rotor posture measurement system by analyzing the sensed magnetic field from arrayed 64 Hall sensors. The basic applicability of the developed rotor posture measurement system is confirmed by the measurement experiments of rotor posture for the rotations around 3 rotation axes that are mutually orthogonal although some future works are necessary to improve measurement accuracy.","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"5 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":"122441995","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 suggest magnetic levitation and linear motors of long-stator design, assuming passive pods. This paper takes a the different approach, yielding minimal energy use per distance per passenger and lowest initial cost. An active pod (short-stator) on wheels with an on-board battery, able to build up speed and regenerate effectively using an inexpensive passive track is proposed. In the stations, power is received from active track-coils to charge the on-board battery. Permanent magnet (PM) track sections enable thrust to speed-up and slow-down. A relatively small rotating induction motor on the wheels enables efficient coasting. Speeding up and slowing down with a linear motor at constant power is effective in terms of component utilization. A mere 100 W/kg (common in present commercial full electric cars) is sufficient to travel long distance at high speed on record low energy consumption (<10 Wh/km per passenger).","PeriodicalId":214273,"journal":{"name":"2019 12th International Symposium on Linear Drives for Industry Applications (LDIA)","volume":"38 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":"132572485","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 estimation method is based on model reference adaptive system (MRAS). Proportional Integral (PI) controller is used to control the speed of LIM. The output of the PI controller is considered as the reference thrust for DTC-SVM.
