Detailed Product Description
Y, YKS, YQF, YKK and YR, YRKS, YRQF, YRKK series medium-scale HV 3-phase asynchronous machines (base no. 335-630) are our own designed products after introducing the design and manufacture techniques of 1980s' 3-phase asynchronous machines of Westinghouse (USA) and ABB (Switzerland). These products were designed with 50 years of design and manufacture experiences of HV 3-phase asynchronous machines and complying with the current national and industry standards. Through tests, it is proven that both the performance and the economic index of these products are advanced even in international market. They have been exported to more than twenty countries and regions, such as Europe, USA, Africa, South-east Asia, Hong Kong and Macau. These products are the substitutes of the old JS, JSQ and JR, and JRQ series machines. The materials used for these machined are refined and they are manufactured elaborately. They are with features of energy-saving, low noise, low vibration, reliable and easy to maintenance. The power grades, electrical performance and the mounting dimensions of these products are all comply with the standards, that is GB755 Basic Specifications for Rotary Machines, IEC34-1 Ratings and Performance of Rotary Machines and JB/T7593, and JB/T7594. According to GB4942.1 and IEC34-5 Invasion Protection Class of Rotary Machines, the Protection Classes for these products are IP23, IPW24, IP44 and IP54. The IP23 machines can be modified to IP44 (pipe ventilation) on request. Products with other IP class can also be supplied. There are three cooling methods for these products, IC01, IC611 and IC81W, according to GB/T1993 and IEC34-6 Cooling of Rotary Machines. Products with other cooling methods can also be supplied. The structure and mounting type of these products is IMB3(horizontal with mounting feet), complying with the specifications in GB997 and IEC34-7 Code for Machine Structure and Mounting Type. These machines can be divided into the following 8 series according to their rotor type, IP and Cooling. The tables in this catalogue list the specifications and outline dimensions of the above 6kV machines. And that of 3kV can derive from these specifications. These machines can be used to drive general machinery, such as compressors, ventilators, pumps, lathes, handling tools and others. They are typically used in industrial companies, such as mines, machinery factories, petroleum and chemical factories, power factories, as the motivity. The motors used to drive the machinery with high inertia, such as blowers, coal mills, steel bar mills, winches, crackers and belt conveyors, will be provided with relevant specifications when ordering. These specifications act as the base of the special design to ensure the reliability of supplied motors.
