General introduction Shanghai Electric Machinery Co., Ltd.abb. As SEMS began to develop cyclocnverter-fed synchronous motors of overhanging type for mine hoists in early 1990s and at meanwhile induced modern design and process technology through cooperation with international leading motor manufacturers. Up to now, SEMC has produced several pieces of the said motors and achieved good results in operation, on base of which a whole series of the cycloconverter-fed synchronous motors for mine hoists has been developed in response to the technology for variable frequency device abb, as cycloconverter-fed. Compared to DC motors, cyclocnverter-fed synchronous motors have good perance in speed regulation and also large capacity of overload without limit in commutation, the largest torque output is always possible within the whole speed range, This type of motors can also save on electricity because the efficiency is 3-5 higher than that of DC motors. Featuring low moment of inertia, light weight, simple structure, high reliability and good convenience for installation and maintenance, the motor is an ideal driving equipment for mine hoists with good technical and economical specifications. SEMC has history of tens of years in manufacturing motors for mine hoists and have got abundant design experience in linking up motors with hoists, all of this can be applied to cycloconverter-fed induction motors. Cycloconverter-fed synchronous motors of TDBS series is the latest model with good perance and appearance, reasonable structure and reliable quality. 二 型号说明 2.
