摘要:
为研究全封闭扇冷式( totally enclosed fan-cool,TEFC) 感应电机额定负载运行时的温度场,以一台55 kW 异步电机为例,运用等效方法对电机实际结构进行简化处理,通过绝缘等效手段建立了实际绕组等效模型,进而建立了电机温度场仿真计算模型,基于导热学基本定律及稳态热传导方程,采用有限元法对其进行稳态温度场计算。计算过程中,通过采用电机内冷却介质等效导热系数的方法解决了转子旋转以及电机内空气流动的问题; 得到了电机各结构件的温升分布特性; 对定子铁心不同位置的温升情况进行了细致研究,分析了转子内部温升分布情况,并对单根绕组的温升以及绕组周向的温升差异进行了数值分析,对样机进行了实验测试,将计算结果与实验结果进行对比,验证了计算方法的准确性。
Abstract:
In order to research the temperature field of the TEFC induction motor under rated load conditions, a 55 kW asynchronous motor was taken as an example. The motor real structure was simplified using equivalent method,and the equivalent model of the actual windings was established by the method of insulation equivalent. Based on the basic law of heat conduction and steady-state heat conduction equation, the simulation model of the temperature field was established and the steady temperature field was calculated
with finite-element method. The problem of rotor rotation and air flow in motor was solved by using the concept of equivalent coefficient of heat conductivity. Temperature distribution characteristics of the motor was obtained. Temperature field of different positions of the stator core was studied in detail. The temperature distribution inside the rotor was analyzed,and temperature rise of single winding and the windings along the circumferential direction was also numerically analyzed. At last the experimental test was carried
out on the prototype,comparing the calculated results with the experimental value,and accuracy of the calculation method was verified.
