摘要

本文研究了一种用于滑翔伞拖曳绞车的小型高效永磁励磁同步电机。出于移动性和安全性的考虑,选择电压仅为48V的电池电源。首先进行了机器的粗略设计。在预先设计后,使用SyMSpace软件工具通过二维有限元法仿真对最终的机器几何形状进行遗传优化。制造完成后,对驱动器进行了现场定向控制调试,并将预期的机器特性与测量结果进行了比较。最后,还实现了两种自感知转子角度估计方法(一种下转速范围和一种上转速范围),并对其作为已安装转子角度编码器的备用系统进行了评估。

Design and Implementation of a 12.5kW PMSM as Paraglider Towing Winch
This work deals with a compact and efficient permanent magnet excited synchronous machine to be used as paraglider towing winch. A battery supply with a voltage of only 48V is chosen for mobility and safety reasons. A rough machine design is first carried out analytically. After predesign, the final machine geometry is genetically optimized by 2D finite element method simulation using the software tool SyMSpace. After manufacture, the drive is commissioned with field-oriented control and the expected machine characteristics are compared with measurement results. Finally, also two self-sensing rotor angle estimation methods (one for the lower and one for upper speed range) are implemented and evaluated as back-up system to the installed rotor angle encoder.
