电机磁场存在磁饱和现象,是一非线性问题,再加上电机结构复杂,无法用解析法求得场的精确解,而图解法既不准又费时,采用差分法则难于处理复杂的界面形状。因此,一般都是将电机磁场简化为磁路,按经验公式进行近似计算。然而在设计电机,研究如何改变磁系统的结构、形状,得到合理的磁场分布时,用磁路进行简化计算的方法就无能为力了。譬如,直流电机主极冲片采用什么样的形状,可使换向器的电位特性较好;电枢轴向通风孔的位置、大小对电机磁场的影响怎样等等,这些涉及磁场分布的问题,都必须求解磁场方程。再有,要准确计算电机的电感、铁损等,也需要知道电机磁场的分布。本文介绍如何用有限元法求解磁场方程,计算电机的磁场分布。

It is necessary that the automatic remote-control system for the marine diesel engine have fundamental logical functions, such as reversing, "starting, accelerating, slowing and stopping. In.addition, it is often required to own normal functions—automatically restarting, automatic avoidance of critical speed, automatically keeping the engine running, and giving alarms and the like. Through the practice of the development of pneumatic remote-control systems for marine engines, the authors present a design of control return in which the above functions may be attained by the use of cut-off high pressure miniature pneumatic logical elements.
