YT SERIES THREE PHASE AXIAL-VENTILATING INDUCTION MOTORSYZP series frequency-conversion speed regulating three-phase asynchronous motor (Hereafter motor is called. ) for metallurgical and hoisting use integrates advantage of frequency-conversion to result in the features of great overloading capacity, high mechanical strength, wide range of speed regulation and stable operation. Its basic technical specifications are in conformance with IEC34-1 and GB755 and all the performance indexes of motors are equivalent to international level of 1990s. The series equipment is suitably applied for various kinds of hoisting and metallurgical machinery, or other similar equipment, as well as in the cases of frequently starting, braking and reversing.Main Technical Datas:
