Y YKK YKS YKKVF Squirrel Cage Rotor Medium Voltage AC Induction Motor High Voltage Motor Asynchronous Motors
---------------------------------------------------------------------------------------------
General description
YKK high-voltage asynchronous motors comply with IEC international standards, and the mechanical dimensions and tolerances of various components comply with the corresponding Chinese and international standards. The protection level of this series of motors is IP54, IP55, etc. The cooling methods are IC611, IC616, etc. The installation method is IMB3, and the corresponding protection type, cooling method and installation method can also be made according to user requirements. This series of motors can also be made into wet tropical, dry tropical, outdoor and outdoor anti-corrosive and outdoor wet tropical.
YKK series squirrel cage high voltage motors can be used to drive various general machinery, such as compressors, pumps, crushers, cutting machine tools, transportation machinery and other mechanical equipment, in mining, machinery industry, petrochemical industry, power plants and other industrial and mining enterprises. Used as the prime mover.
The rotor of the motor adopts the squirrel cage structure, which is balanced by high-precision verification. The motor runs smoothly and the vibration is small. The motor is provided with a cylindrical shaft extension. It can also be made into a double shaft extension according to the user's needs. According to the motor power and speed, the bearing adopts two types of rolling bearing and sliding bearing. The rolling bearing is provided with non-stop injection and oil discharge device. Under the condition of continuous running of the motor, grease can be added regularly to maintain and maintain the motor. The sliding bearing is an end cap type spherical plain bearing, which adopts pressure oil lubrication or oil ring self-lubricating compound lubrication method, and measures for preventing shaft current generation are adopted at the same time. The motor adds a temperature measuring device to the bearings and windings to monitor the temperature rise during motor operation.
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.
The Implication of the symbol
By 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:
