Abstract

The present work deals with steady state air flow analysis of electric motor having 20 hp rating running at 1450 rpm. The motor is being used to run the belt pull system to drive the exhaust fan in the industry. Air flow analysis of electric motor is carried out to predict temperature distribution over the motor. The modeling of the complete motor is done in CATIA. Meshing of whole geometry is done in ICEM CFD14.5. Results are obtained using FLUENT. In this research only copper losses and iron losses are taken into consideration based on the output obtained from electrical simulation software. The copper and iron losses are found out from electromagnetic analysis using Motorsolve software. Losses are treated as heat source or input to find out temperature distribution. To improve the accuracy, the computational fluid dynamics (CFD) analysis is performed by considering the air flow around casing and fins and thermal generation due to the losses. It is observed that there is a significant rise in temperature on casing and on fins for 30 °C ambient temperature.

20马力三相异步电动机气流分析

本文研究额定功率为20马力、转速为1450转的电动机的稳态气流分析。电机在工业上被用来运行皮带牵引系统来驱动排气扇。对电动机进行气流分析，预测电动机的温度分布。在CATIA中完成了整个电机的建模。整个几何体的网格划分在ICEM CFD14.5中完成。使用FLUENT计算结果。在本研究中，基于电仿真软件的输出，只考虑了铜损耗和铁损耗。利用Motorsolve软件进行电磁分析，计算出铜和铁的损耗。将损耗作为热源或输入来计算温度分布。为了提高精度，计算流体力学(CFD)分析考虑了机匣和翅片周围的气流以及损失产生的热量。可以观察到，在30℃的环境温度下，套管和翅片上的温度显著升高。
