In the project, we studied and developed elementary technology for fully superconducting linear actuators with high temperature superconducting (HTS) primary windings and a thruster made of HTS bulks.An electric direct-drive linear actuator with high thrust force has great potential needs in the field of industrial automation. Rapid and exact force control is possible by the electric direct-drive system, which is difficult by other methods such as hydraulic system and gear-and motor system. To obtain high thrust force using an electric direct-drive system of copper windings, however, current density of the windings should be very high and the joule heating in the windings becomes very high. Therefore, the actuator needs a large capacity power supply and a large size water cooling system. On the other hand, the fully superconducting actuator can be more compact and have higher thrust force with much smaller power loss than the copper actuator. It only needs small size power supply and the cooling system can be much smaller than the water cooling system for the copper actuator.We made a model actuator with a primary winding wound of Bi/Ag sheathed tape and thruster with a YBCO bulk and studied basic of thrust force.We made an analytical model to calculate the thrust force and showed the validity of the analysts. We also studied AC loss characteristics of the primary windings and the bulk superconductors which are important data for designing the actuator. We developed a method to magnetize a bulk array with alternative polarity for the thruster and proved the method worked well.

在该项目中，我们研究并开发了基本技术，用于具有高温超导（HTS）初级绕组和由HTS大量制成的推进器。电动直接驱动系统可以快速而精确的力控制，这是其他方法（例如液压系统和齿轮和电动机系统）难以控制的。为了使用铜绕组的电直接驱动系统获得高推力，但是，绕组的当前密度应非常高，并且绕组中的焦耳加热变得非常高。因此，执行器需要大容量电源和大尺寸的水冷却系统。另一方面，与铜执行器相比，完全超导的执行器可以更紧凑，并且具有更高的推力，并且功率损失要小得多。它只需要小尺寸的电源，冷却系统可能比铜执行器的水冷却系统小得多。我们制作了一个模型执行器，该执行器具有带有BI/AG鞘胶带和推进器的主要绕组伤口，并用YBCO的体积进行了推力，并研究了推力力的基础。我们制作了一个分析模型，以计算推力力并显示分析性的Valities。我们还研究了主要绕组和大量超导体的交流损失特性，这些绕组是设计执行器的重要数据。我们开发了一种方法来磁化具有替代极性的散装阵列的推进器，并证明了该方法效果很好。
