低惯量电动机低惯量电动机low-inertia electrical machine 筒形转子电动机电枢的结构示意图。这种电动机由套筒形笼型转子和装在套筒内的内定子铁芯两部分组成。套筒形转子有一个用电工钢制成的空心套筒和嵌在套筒上的一些铝质笼型导条,套筒两端由法兰盘固定在输出轴上。内定子铁芯用硅钢片叠成,两端用滚珠轴承支撑在输出轴上。它和输出轴之间只有轴承中产生的摩擦阻力,因此,由图1低惯t套筒形转子电动机电枢结构示意图1一铝导条;2一套筒;3一 内定子铁芯内定子铁芯所增加的转动惯量很小,电机的转动惯量主要取决于套筒形转子。这种转子比杯形转子机械强度高,功率可大为增加。但这种转子结构复杂,制造困难。 低惯t无槽直流电动机这种电动机尽量选用较小的电枢直径和较长的电枢长度,采用无槽电枢结构,如图2所示。无槽电枢的铁芯先用绝缘带缠绕一层,然后用环氧树脂将绕组固定在电枢表面上,再缠绕一层绝缘带,其机械强度与有槽电枢相近。 图2低惯t无槽 直流电动机电枢 结构示意图1一绕组.2一环氧树脂; 3一绝缘带,4一铁芯 由于电枢无槽,不必考虑气隙磁密因齿磁密过高而受到限制,设计电动机时可选取较高的气隙磁密,使无槽电枢铁芯减小,一般比有槽电枢大约可减少一半;又由于电枢绕组固定在无槽电枢表面上,冷却效果较好,设计时可选取较高的电流密度、截面较小的导线,这使电枢重量减轻,转动惯量降低;此外,还由于电枢绕组固定在电枢铁芯表面上,绕组的电感较小,使电抗电动势减小,从而改善了电动机的换向,减小了电动机的机电时间常数,快速响应好。d一guonl.ong dIQndongjl低惯t电动机(IOw一inertia eleetriealma-chine)采用专门的措施减小转子转动惯量的拉制电机。其工作原理与同类型的伺服电动机相似。由于低惯量,使电动机灵敏度高,机械过波过程短,控制系统准确性好。常用的低惯量电动机有低惯量套筒形转子电动机和低惯量无植直流电动机两种。 低惯t套筒形转子电动机图1所示为低惯量套
