摘要:
为了得到某变频调速隐极同步电机对应的通风结构内流体流动与传热的特点,建立 1 /8 整机结构的三维流场物理模型,基于计算流体动力学原理,采用有限体积法对流体场控制方程进行数值模拟,可以得到电机内不同通风段各通道内空气流量、速度和压力分布特点。结果表明,转子端部采用弧段进风、直段补风布置时,在转速分别为 3 120 r/min、4 800 r/min 时,进入定、转子的风量分配比率并无明显变化,风路最长的槽弧段绕组内冷风量最少,应注意该处绕组温度是否超温。为电机设计通风系统提供参考。
Abstract:
In order to obtain the fluid-flow and heat-transfer characteristics of a variable-frequency adjustable-speed non-salient-pole synchronous machine,the three dimensional physical model of the 1 /8 structure of whole motor was established. The flow fields equations were solved numerically based on finite volume method according to the computational fluid dynamics(CFD). Then distribution characteristics of air flow rate,velocity and pressure in the non-salient motor ventilation system were received. The results show that the distribution percentage of cooling air flow rate flowing through the stator and rotor is essentially constant with the rotor speed of 3 120 r/min and 4 800 r/min respectively,as adopting primary air inlets at rotor end arc section and secondary air-supplement inlets at end straight section. There is the least air flow rate in the longest inner channel of arc winding section,so the problem of excessive temperature of the winding should be paid attention to. The conclusion provides reference for structure design of ventilation systems.
