Abstract

It is very important to efficiently design induction motors from the thermal point of view. For this task it is crucial to compute correctly the induced currents in the rotors, because heating is principally generated there. The currents flowing in the coils of the stator are another source of heating. This paper presents a weak coupled model of the electromagnetic and the thermal phenomena for transients. Special attention is paid to model correctly the air gap zone for the thermal part.

异步电机暂态的耦合磁热模型
从热的角度出发,有效地设计异步电动机是非常重要的。对于这项任务来说,正确计算转子中的感应电流是至关重要的,因为加热主要是在那里产生的。定子线圈中流动的电流是另一种发热源。本文提出了一种瞬变电磁现象和热现象的弱耦合模型。特别注意的是对热部件的气隙区进行正确的建模。
