毕业设计(论文)-三相异步电动机的电磁设计精选

摘 要 Y2系列电机是在Y系列电机基础上更新设计的一般用途电机,它具有结构简单、制造、使用和维护方便,运行可靠,以及重量轻,成本低等优点,在电机噪声、振动水平优于Y系列电机,外观更加满足国内外的用户需求,本文为Y2-112M-2的电磁设计。 在设计过程中,掌握了中小型三相感应电机的设计原理,熟悉相关的技术条件,基于给定的参数结合相关的技术条件,确定与电机的电磁性能有关的尺寸,选择定、转子的槽数和槽配合,确定槽型尺寸,选定有关材料,编程进行电磁计算,结合前面的数据计算出相应的工作性能和起动性能,包括效率、功率因数、最大转矩倍数、起动转矩倍数、起动电流倍数等。为了减小误差和计算量,还在MATLAB中编写了电磁计算程序。此外,本设计还用CAD绘制了定、转子冲片图以及定子绕组分布图,最终使技术指标符合任务书的要求。 通过对电机性能尺寸的确定,以及对槽型的选取,选定了有关尺寸,通过编程的反复调试,使其技术指标符合任务书的要求,最终设计出符合任务书要求的电机。 关键词:Y2-112M-2三相异步电动机;定、转子;电磁设计计算 Abstract Y2 series motors is designed on the basis of Y series motor update general purpose motor. it has a simple structure, convenient manufacture, use and maintenance, reliable operation .as well as light weight, low cost advantages, the motor noise and vibration level is better than that of Y series motor. appearance more meet the needs of users at home and abroad, this paper designed for electromagnetic Y2-112m - 2. In the process of design, master the design principles of small and medium-sized three-phase induction motor, familiar with relevant technical conditions, based on the given parameters combining with related technical conditions, determine the size of the associated with the electromagnetic performance of the motor, \option, rotor slot number and groove, groove type size ,selected materials programming electromagnetic calculation, Finally, combined with the previous data to calculate the working performance and the corresponding starting performance, including efficiency, power factor, the maximum torque, starting torque, starting current ratio etc. In order to reduce the error and the amount of calculation, prepared electromagnetic calculation program in MATLAB. In addition, the design also drawing, the rotor and the stator , windings distribution prints with CAD. the technical indicators in line with the requirements of specification. To determine the size of the motor performance, as well as to the trough type selection, the selected size, by the repeated debug programming, make the tech
