微型电机电源的设计

某微型电机电源是将220V/50Hz的交流电,转换为两相相位差为90°、频率为1.5kHz的方波信号,并且为了克服以往微型电机有时在低压时无法启动时的现象。本文根据微型电机在低压下可靠启动的要求,设计了一种高低压转换电路,以达到高压启动低压运行。

方圆形铁芯无搭边冲裁在分马力电机制造上的应用

全国统一设计的AO_2、BO_2、CO_2、DO_2及YL系列分马力电机均选用园形铁芯冲片,洗衣机、电风扇、电冰箱等家用电器所配用电机,一般选用方园形铁芯。方园形铁芯冲片适合在高速冲床上选用卷料进行无搭边冲裁,这可以大大提高劳动生产率及材料利用率。但高速冲床投资大,卷料市面供应紧张。

Global Evaluation of Energy in Hybrid M-HTFC/MGT Systems in Cogenerative Arrangement

This work concerns the study of HSs （Hybrid Systems） that are made up of the integration of M-HTFC （Medium and High Temperature Fuel Cell） and MGT （Micro-Gas-Turbine）. Different typologies of hybrid systems are taken into account, which differ from each other in their plant layouts. The plants are considered in cogenerative arrangement. The aim of this study is to carry out an energetic analysis of the HS considered to obtain an analytical expression to depict the system operating in cogenerative arrangement. An energetic comparison among the systems analyzed based on some indexes is effected, which allows an evaluation of the plants performances in cogenerative arrangement. An energetic analysis is carried out, which is based on a ＂black box＂ depiction of the plant in which the components and the mutual interactions are highlighted. The fuel cell component of the plant is not analyzed as a black box, but each element that constitutes it, is elaborated as a subsystem.
