1. General Description Catalogue Download

Y, YKS, YQF, YKK and YR, YRKS, YRQF, YRKK series high voltage three-phase induction motor is a new product which introduced and developed by our company in 1980s, it has experienced a history of over 30 years. With the improvement of insulation material performance of the motor in recent years, the application of low consumed silicon steel sheet, the enhancement of level, and the optimization and improvement of design, which have the ability to reduce all kinds of consumptions of motors so as to increase the motor capacity. Combined with the experiences in designing and manufacturing of the high voltage three-phase induction motor in the past 60 years, our company has made the latest optimization and design once again to comply with the national and industrial demands. The tests have proved that, the new series of products have reached or been close to the globally advanced level no matter in terms of technical performance or in economic performance. The products have produced in a large volume and exported them to over 20 countries and regions, such as the Europe, America, Africa, Hong Kong and Macao, etc and all parts of China, and they have got the good appraisal form the users.

This series products adopt the high quality materials, good manufacturing process, have the characteristics of high efficiency, energy saving, small vibration, reliable operating and convenient for mounting and maintenance.
The power grade, electric property, mounting dimensions and tolerance are coincident with national standard GB755 Rotating Electric Motor Rating and Property, International Electrical Committee standard IEC34-1 Rotating Electric Motor Rating and Property and machinery industry standards etc.

The enclosure protections of this series of motor include 5 types, i.e. IP23, IP44, IP54, IP55 and IP56 in accordance with the standard of the GB4942.1 and IEC34-5 Enclosure Protection Class of Rotating Electrical Machine. The IP23 motor can be changed to IP44 (pipeline ventilation) or IPW24 (climate protection type). If the users need other protection class, we may also provide relevant products.

There are 3 cooling methods of this series of motor, i.e., IC01, IC611 and IC81W in accordance with the standards of GB/T1993 and IEC34-6 Cooling Methods of Rotating Electrical Machine. If the users need other cooling methods, we may also provide relevant products.

The structure and Installation method of this series of motor is IMB3 (horizontal with footing), and complies with the specifications in GB997 and IEC 34-7 Motor Structure and Mounting Type Code.

This series of motor may be classified into 8 series in accordance with the rotor model, protection class and cooling method:

2. Application Ranges

This series of motor may be used for driving all kinds of general machines such as the compressor, ventilation fan, water pump, stock-removing machine, transportation machines and other mechanical equipment, and are applied as the prime mover in all industrial and mining enterprises such as the mine, machinery, petrochemical industry and power plant, etc. If the users place an order for the motors that are used for driving the machines with huge rotary inertia such as the blower, coal grinder, rolling machine, crusher, belt machine, etc, they shall provide us with relevant technical data, sign the technical agreement with us as the basis for specific design of motor to ensure the reliable operation of motor.
