Abstract

The ironless linear induction motor device can be used for any application which requires a large motion span or rotation restrictedly by the ironless feature due to the strong magnetic field environment. One of the possible applications is ITER diagnostics shutters. The tokamak reactor systems have a severe radiation issue during the operation. The traditional Kapton-insulated wires have significantly lower radiation resistance than an expected large radiation dose at ITER Motion Stark Effect (MSE) shutter location. Furthermore, the traditional single-sided linear induction motor winds the wire to make the N-turn pitch coils independently and then connect them in series to make a one-phase winding. Therefore, it is a big challenge to make so many radiation-protection connectors in such a limited space as inside the vacuum vessel of fusion reactors. The approved mineral-insulated kinds of cables need a large bend radius for the end turns, so the traditional single-sided linear motor with two-layer three-phase windings need to be upgraded to the tubular linear motors.

The new proposed tubular ironless linear induction motor can not only overcome the large bend radius issue with the mineral-insulated cables but also allow the motor coils wound continuously around the tubular-shaped stator, forward and backward N times to make a N-turn winding for each phase, in order to resolve the radiation protection issue with the winding connection. The 3D transient Maxwell electromagnetic model with a tubular three-phase linear induction motor has been analyzed. This paper will present the detailed design and winding method of ironless linear induction motor actuators, and results of the 3D transient numerical simulation of the actuator performance.

一种新型无间断绕组管状无铁直线感应电动机

无铁直线感应电机装置可用于任何由于强磁场环境而需要大运动跨度或受无铁特性限制的旋转的应用。其中一个可能的应用是ITER诊断开关。托卡马克反应堆系统在运行过程中存在严重的辐射问题。在ITER运动斯塔克效应（MSE）快门位置，传统的卡普顿绝缘导线的辐射电阻明显低于预期的大辐射剂量。传统的单面直线感应电动机将导线单独绕成n匝螺距线圈，然后串联成单相绕组。因此，在核聚变反应堆真空容器内的有限空间内制造如此多的辐射防护连接器是一个巨大的挑战。经批准的矿物绝缘电缆对端匝弯曲半径要求较大，因此传统的两层三相绕组单面直线电机需要升级为管状直线电机。新提出的管状无铁直线感应电动机不仅克服了矿绝缘电缆弯曲半径大的问题，而且使电机线圈连续绕在管状定子上，前后N次，每相形成N匝绕组，解决了绕组连接时的防辐射问题。分析了管式三相直线感应电动机的三维瞬态麦克斯韦电磁模型。本文将介绍无铁直线感应电机执行器的详细设计和绕线方法，以及执行器性能的三维瞬态数值模拟结果。
