绕线方式对永磁同步电动机温度场的影响分析

Analysis of Temperature Field for Permanent Magnet Synchronous Motor with Winding Mode

定子绕组铜耗是引起电机温升的主要原因之一,绕组绕线方式的不同产生的绕组铜耗不同,进而对电机温升的影响不同。为研究绕线方式对永磁同步电动机温度场的影响,以单层同心式绕组和双层叠式绕组为例,采用Ansoft软件建立了两种绕线方式的永磁同步电动机模型并仿真计算电机铜耗和铁耗,利用Ansys Workbench软件仿真计算了两种绕线方式的电机温度场,通过对比温度场结果数据,得出在额定载荷下双层叠式绕组对永磁同步电动机温升影响较大。

The copper loss of the stator winding is one of the main reasons causing the motor temperature rise. Different winding mode produces different effects on the copper loss and has different effect on the temperature rise of the motor. In order to research the winding mode on the temperature field of the motor,taking single-layer concentric winding and double stacked winding for example, using Ansoft software established two kind model of permanent magnet synchronous motor and calculated the copper loss and iron loss,using Ansys Workbench software calculated the temperature field of two kind of model. At last the comparisons of analysis results with test data are proposed to the conclusion,which the double stacked winding has a more great influence on the temperature rise of permanent magnet synchronous motor under the rated load.
