第一部分介绍

1.1电机特性

在过去的几年里,牵引电机在控制能力的高技术水平上发生了很大的变化。

车辆制造商和用户对于现在他们所应用的电动车辆电机和控制系统正不断地期望有更大的提高和灵活性。

为了适应这些市场需求,牵引系统设计者们被迫开发新的思路以减少成本提高整个系统的功能和特性。

我们正在发展几代的设计,从而能够让市场感受到当今技术的优势,并盼望着能有新的发展出现。

GE已经开始介绍第二代系统，它用于他励直流并绕电机。

他励直流电机系统能提供很多已经建立的先进的交流系统的特性。

从历史上看，大多数的电动车辆依靠串励电机设计，这是因为在低速时，它是有产生很大转矩的能力。

但是，随着高效率系统需求的增加，例如，用户需要特殊转矩的系统。

并励电动机被认为优于串励电动机。

在很多应用中，通过在他励电机中，分别控制励磁和电枢电流，串绕和并绕电机的最佳优点能被很好地结合。

　　正如图所示的典型性能曲线，很明显串励电机在低速特性上有很高的转矩。

　　在并激电机中，励磁直接通过电源连接，因此它独立于负载和电枢电流。

如果场强保持恒定，那么转矩将直接随着电枢电流的变化而变化。

如果电机上的机械负载增加，那么电机减速，同时，减少反电势（反电势取决于速度和恒定的场强）。

减弱反电势可允许电枢电流增加，用于提供增加的机械负载所需的更大转矩。

如果机械负载减小那么与上个过程相反。

电机速度和反电动势增加，而电枢电流和转速则会下降。

因而无论负载何时变化，速度也发生变化，直到电机再次达到电平衡。

　　在并励电机中，在平地状态下以无载到正常满载，速度的变化不超过10%，由于这个原因，并励电机可认为是恒速电机。

　　在他励电机中，在正常的运转过程中，电机以固定磁场并励电机形式运转。

可是,当需要额外的转矩时，例如，爬行非平坦地带，象斜坡和同类的情况，增加励磁电流来提供高水平的转矩。

在大多数情况下，电枢与励磁的安匝比与相当尺寸的串激电机相似。

暂且不论上述的恒功率特性，还有很多增加性能降低成本的特性。

下面的叙述是这些
