Product Description 1. General introduction1)YKK ,YKS,Y2 Series high voltage three-phase asynchronous motors (Frame No.355-1000) mounting dimensions and tolerance are coincident with China standard GB755<Rotating Electrical Machines-Rating and Performance>, International Electrical committee standard IEC34-1<Rotating Electrical Machines-Rating and Performance>and machinery-profession standards JB/T/7593 JB/T10315.1 etc.The grade of protection for outer cover is in accordance with GB4942 and IEC34-5 <Rotating electrical machines- enclosure ingress protection>standard, there are four grades IP23, IPW24, IP44 and IP54. The IP23 grade can update to IP44(Tube Ventilation) according the customer's request. Also provide other protective grade specially.The cooling method is according to the GB/T1993 and IEC34-6 standard <Cooling method of Rotating Electrical Machines>. There are three kinds of cooling method IC01,IC611 and IC81W. Also we can provide other cooling method according the customer request.The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 <Classification of types of construction and mounting arrangements for rotating electrical machines>(IM code) standards.YKK-series (2Kv~11Kv) squirrel-cage three phase asynchronous motor, is building on the advanced technology in the nation. The protection degree of the motor is of IP23(according toGb4942.1), and the cooling method is IC01(according to GB/T1993).The motors has a lot of advantages such as height efficiency, enerty-saving, low noise and vibration ,light weight and reilable performance. THey are easy for installation andmaintenance. The motor has high insulation class and moistureproof capacity.The motor is used to drive various mechanical equipments such as blowers, pumps, crushers, storkremoing machines and other equipments. It can serve as the prime movers in coalmines, mechanical industries, powerplants and various industrial enterprises.2)Structure specification The frame is made of steel plate being welded up into form of square tank shape with light weight and firm rigidity .Stator is a outer-press-assembly structure, the stator winding is a F grade insulation, at the winding's end part being firm banded.The whole stator has been treated with VPI technology to make stator with a robust body and good electrical and moisture resistance.The rotor can be developed into two modes casting aluminum and copper bar mode. Casting aluminum rotor is casted with pure aluminum. Copper-bar rotor is made by copper bars wedges in the slots, then at the bar's each end to be soldered with a end-ring by reliable soldering technology. At the end of process, it must be immersed in lacquer once to strengthen the integration.Either rolling or sleeve bearing may be adopted, the protection grade of bearing is IP54. For the rolling bearings mode, the rolling bearing must be lubricated with grease, and the motor must have oil-inlet and oil-exhaust devices, motor can also be non-stop oil injection. For the sleeve bearing mode, the oil supply system for the bearing must be prepared by customers. But the efficiency for sleeve bearing motor will be permitted a little decrease with respect of the technical data table and that is permissible in according with the relative stipulates of the standard issued by Ministry of Machine Building.The main terminal box is designed by Germany DIN standard. The grade of protection is IP54. The terminal box for standard motor is located at the right side (Viewed from axle extension). Also can be mounted at left side according customer's requirement. The outlet hole of terminal box can face up, down, right and left four directions. There is a independent grounded device in the main terminal box.Normally the motors axle is single extension mode, the key is a planar key mode. We also can provide double shaft extension mode according customer's requirement.We can install temperature measurements in stator and bearings. And install inner space heaters for moisture protecting during stoppage.3)The Implication of the symbolBy GB4831 stipulation, the motor's type is composed of product symbol and specification symbol in sequence.The product symbol is demons treated by motor series symbols, its implication is as following: Y---------squirrel-cage rotor three-phase asynchronous motor. YKS------Enclosed squirrel-cage rotor three-phase asynchronous motor with air-water cooler YKK------ Enclosed squirrel-cage rotor three-phase asynchronous motor with air-air cooler The specification symbol is composed of centre height, iron-core length number and number of poles.Example:DetailsYKK series:Frame sizes: 355-1000 Rated output: 185-8000kWInsulation class: F Degree of protection: IP54 /IP55Enclosure: IC611 Mounting: HorizontalRotor: Squirrel cage Bearing: Rolling bearing or sleeve bearingVoltage: 6kV, 10kV2. Brief ConstructionThe motor adopts compacted box structure, welding-jointed steel plate forits frame, light weight, rigid in construction, there is closed air to air coolers on the stator frame convenient for installation and maintenance.Stator winding adopts F class insulation and its end adopts firm binding. The whole stator adopts solvent-free varnish Vacuum pressure impregnation(VPI) to ensure the stator has excellent electric property and humidity resistance.Rotor is made of cast aluminium or copper bar. Aluminium rotor is made of pure aluminium, copper barwedging copper rotor enhances the entorety of rotor.The motor adopts rolling bering or sliding bering, according to the output power and rotary speed. Bearing protection grade normally is IP44. If the motor's protect grade increases, so does the berings'. Rolling bearing adopts iubricating gresse and its grease charger and discharger can be charged or discharged without stopping the motor.The junction box is of IP54 protection grade and it is usually mounted on the motor's right side(viewed from shaft extension end.) It is also can be mounted on the left side and its outlets have four optional orientations(up, down, left or right.) Separated grounding unit is available in main junction box, too.3.
