摘要
电机在各行各业的广泛应用,推动了中小型电机行业的发展不断壮大,因此研究中小型电机存在重大意义。本课题主要是在熟悉三相异步电动机的原理的基础上,根据设计要求设计一台小型三相鼠笼式异步电动机。首先确定电机的电磁负荷和电机的主要尺寸,然后分别对电机绕组、电机铁心进行设计,并且对设计电机的参数、工作性能进行核算,反复调整,直到设计的参数符合设计任务的要求。在初选方案的基础上改变气隙大小、改变定子匝数、和改变铁心长度进行了几个方案设计,最后对所有设计方案进行比较,优化设计。
关键词电机、电磁设计、改变参数
ABSTRACT
The electrical machinery in all the various trades' and occupations'widespread application, impelled the middle and small scale electricalmachinery profession development unceasingly to expand, thereforestudied the middle and small scale electrical machinery existencegreat significance. This topic mainly is in the familiar three-phaseasynchronous motor principle foundation, according to designs therequest to design a small three-phase mouse cage type asynchronousmotor. First determined the electrical machinery the ismload and the electrical machinery main dimension, then separately tothe electrical machinery winding, the electrical machinery iron corecarries on the design, and to designs the electrical machinery theparameter, the operating performance carries on the calculation,repeatedly adjusts, conforms to the design duty requirement until thedesign parameter. Changed the air gap size, the change stator numberof windings in the primary election plan foundation, and the changecore length has carried on several plans designs, finally carried parison to all design proposal, the optimized design.
Key word Electrical machinery, ism design, changeparameter
