This research project titled "Development of Linear Synchronous Motor for High Speed Conveyance with Field Flux Control Function" has been carried out from 2001 to 2002 in faculty of engineering, Nagasaki University. The aim of this project is to develop a new type linear synchronous motor (LSM). The motor is based on half-wave rectified brushless excitation. As the field flux is controllable by varying armature current, field weakening operation is possible in high speed region.Principal results obtained by this research are as follows ;1. The experimental machine is designed and built. The 12 poles and 2 m long armature is settled on the ground. The armature winding is conventional 3-phase windings. The suspended mover has 4 poles field windings short circuited with a diode.2. Drive system is designed and built. The IGBT inverter produces 3-phase currents with the mover position, in which torque current component and excitation current component are superimposed.3. It is confirmed experimentally that the new LSM reciprocates as instructed. Fundamental performances are measured, for examples inductance distribution, current wave form, thrust.4. Optimization of mover configuration is carried out using FEM. The objective function is thrust ripple caused by detent force and vertical force (attractive force). Tow type configuration, unsymmetrical one and divided into two parts one, are proposed for minimizing both objectives.

2001年至2002年，长崎大学工程学院开展了“具有磁场磁通控制功能的高速运输用直线同步电机的研制”课题。本课题的目的是研制一种新型直线同步电机。该电机基于半波整流无刷励磁。由于磁场的磁通可以通过改变电枢电流来控制，因此可以在高速区进行弱磁操作。本文的主要研究成果如下：1.设计并搭建了实验装置。12根杆长2米的电枢轴安放在地面上。电枢绕组是传统的三相绕组。悬挂的动子有4极励磁绕组，用二极管短路。设计并制造了驱动系统。IGBT逆变器在动子位置产生三相电流，转矩电流分量和励磁电流分量叠加在一起。实验证实，新的LSM是按指令往复的。测量了电感分布、电流波形、推力等基本性能。利用有限元方法对动子结构进行了优化设计。目标函数是由阻尼力和垂直力(吸引力)引起的推力波动。为了最小化这两个目标，提出了非对称和分成两部分的两种结构。
