1、哈尔滨理工大学学士学位论文单相电容运转电动机的设计摘要单相感应电动机是利用交流电的单相电源供电的一类电机。广泛应用于家用电器（电风扇、电冰箱、洗衣机等）、空调设备、电动工具、医疗器械及轻工设备中。单相电容运转电动机，其最大特点是额定运行时的力能指标优良，与同容量的其它单相感应电动机相比较，它的重量较轻、体积较小、效率和功率因数高。它特别适用于轻载起动和要求长期运行的场合，如洗衣机、空调设备等，是产量最大、应用最广泛的一类单相感应电动机。因此，对单相感应电动机，尤其是电容运转式单相感应电动机进行研究，对于提高人们生活质量，推动科技进步以及节约
2、自然资源及能源等，有着极大的价值及现实意义。其结构特点是接在单相交流电源上的主副两绕组，在空间错开/2电角度，主绕组电感大，副绕组电路中串入运转电容器，转子上有笼型绕组。起动及运行过程中，主副两绕组同时工作。堵转转矩小，堵转电流小，有较高的效率及功率因数。关键词 单相电容运转电动机；笼型转子；设计-II-哈尔滨理工大学学士学位论文Thesingle-phaseasynchronousmotorAbstractThesingle-phaseasynchronousmotorisusesthealternatingcurrentasingle-
