高温超导体（HTSs）具有自稳定特性，能产生强磁悬浮力，因此在磁悬浮交通系统中的应用备受关注。对于直线运动的运输，直线驱动是一个明显的优势。本文介绍了一种永磁直线同步电动机的设计和分析，用于驱动一个小型的原型车与PM-HTS块用于悬浮。直线电机由位于车体两侧的永磁体和位于侧轨槽内的定子绕组组成。三相绕组由三相逆变器供电，并采用无刷直流控制方案进行控制。对样机的磁场和驱动力进行了详细的分析和计算。
High temperature superconductors (HTSs) can produce a strong magnetic levitation force with self-stabilizing feature and hence have attracted much attention for applications in maglev transportation systems. For the linear motion of transportation, a linear drive is an obvious advantage. This paper presents the design and analysis of a permanent magnet (PM) linear synchronous motor for driving a small-scale prototype vehicle with PM-HTS bulks used for the levitation. The linear motor consists of PMs on the vehicle sides and stator windings in the slots of side tracks. The three phase windings are supplied by a 3-phase inverter, and are controlled with a brushless DC control scheme. Analysis and calculation details of magnetic fields and driving force about the motor prototype are presented.
