Product Description

Product Description

YLS, YLST, YLKK, YLKKT, YLKS, YLKST series high voltage three-phase induction motor 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, even all over the countries such as the Europe, America, Africa, Hong Kong and Macao, etc as well as 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 IMV1, and complies with the specifications of the GB997 and IEC 34-7 Motor Structure and Mounting Type Code.

Application  
This series of motor may be used for driving water pump 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.
Normal operation conditions for motor:

1. Sea level is not over 1000m;
2. The highest ambient temperature does not exceed 40ºC; the lowest ambient temperature for the motor with rolling bearing is -15 ºC, and for the motor with sliding bearing, the lowest ambient temperature is 5ºC;
3. For the YLKS and YLKST series of motors, the temperature of cooled water in the cooling inlet is 5~33ºC;
4. In moist month, the monthly overage highest relative humidity is 90%, at the same time, the monthly overage lowest temperature is not over 25ºC;
5. The frequency of power source is 50Hz±l%;
6. The variation of work voltage is not over rated voltage±5%;
7. Motor rating is continuous operation system SI;
8. YLST, YLKKT, YLKST series of motors may undertake axial thrust 3~60t.

Construction Description
The medium sized motor employs the internationally popular box structure, and the frame and end cover is welded with steel plate featuring the good stiffness and light weight. After removing the protective cover (or cooler), we may observe and touch the inside of the motor, which is convenient for the installation and maintenance of the motor. The stator employs the external pressing structure. The stator winding employs the F-level insulation material and anti-corona material. The fixing of winding terminals employs the reliable special binding process. The whole stator employs the vacuum pressure impregnation F-level solventless paint (VPI) for treatment. Thus, the motor has the excellent and reliable insulation performance and the ability of damp-proof and shock resistance.
The squirrel rotor employs both cast aluminum and cooper, running reliably.
As for the motor whether undertakes axial thrust and the size of axial pushing power, there are rolling bearings or sliding bearings to be used for upper bearing structure of motor. But only rolling bearing for lower bearing structure. The motor employs the rolling bearing structure has the oil filling and exhausting equipment without stopping the machine.
The main terminal box employs the sealed structure, and the protection class is IP54. The inlet holes of terminal box may be switched to the upper, down, left and right directions. The box has the separate grounding terminals.

Starting of this series motor
The squirrel cage rotor of induction motor has adopted the advanced computer technique to calculate the temperature and pressure of the squirrel rotor, thus to avoid the motors destroy at an early period because of the motor's overloaded while starting. So, we suggest users to check the items as below:

1. The moment of inertial ( after being converted to motor's rotating speed) of the rotating part of mechanical equipment should not over these values of (loading J's) item shown in the technical table;
2. Customers should guarantee the voltage of electric network across the motor's terminals not lower than 85% of the rated value during starting;
3. The resistance moment feature of driven machines is the resistance moment feature of water pump and fan.

Under the above-mentioned conditions, motor may be permitted to be started at actual cold condition for twice continuously, or at hot condition for once, the interval of two times starting is natural stoppage. The restarting of the motor over the above times should be one hour later.
If the moment of inertia of the mechanical rotating part of the driven machinery is over the value shown in (loading J) item of technical data, or there is a requirement to start motor frequently, or it is possible to start the motor under heavy loading, it is necessary to contact with our company for negotiating about specific design so as to ensure the reliable start-up of motor.
