Product Description

Medium Voltage High Voltage Wound Rotor Slip Ring Motor
---------------------------------------------------------------------------------------------

Applications: 
Ideal for driving all kinds of general machinery, such as water pump, fan, compressor, crusher and etc.

General description

YR series large seize 6kV wound rotor three-phase asynchronous motor is a new series of products that our company introduces and digests the advanced technology of WESTING-HOUSE Company and combines decades of motor manufacturing experience of our company. It is the replacement product of JR old series.
YR series large size 10kV wound rotor three-phase asynchronous motor is another series of products carefully built by our company on the basis of the successful development of medium-sized 6kV wound rotor three-phase asynchronous motor. This series of motors can be directly used in 10kV power grid. Compared with the 6kV motor, it has the advantages of simplified equipment, reliable operation, investment saving and energy consumption reduction.

Structure specification
YR series motor's rotor winding adopt copper conductors with the insulation material whose insulation class is F. The welding between the windings, the lend-out copper conductors and windings all adopt silver-copper-welding to ensure the motor running reliably. 
YR series motor has the box-type construction, which was made up of steel plate welded with lightweight and good stiffness. On top of the motor is the protective cover, convenient to maintenance and replacement. The stator adopts the press construction; the winding with class F insulation and VPI impregnating, which ensure the reliable of the insulation, the mechanical stress and the capable of resistant humidity. The basically protection class is IP23; IP54 motor can be supplied according to requirement.

The stator coil is buried with the temperature measuring component, and the change of the coil temperature is observed. The specification of the temperature measuring component can be determined according to user requirements.
If you need to add a heater inside the motor, you must specify it when ordering.
The motor terminal cable is generally in the lower part of the motor, and the terminal cable can also be designed according to customer requirements and must be installed on the wall of the machine base.

Details
YRKK SERIES

• Frame sizes: 355-1000                         
• Rated output: 185-5000kW
• Insulation class: F                              
• Degree of protection: IP54 / IP55
• Enclosure: IC611(Air-air heat exchanger)         
• Rotor: wound-rotor with collector rings                    
• Voltage: 6Kv, 10Kv

Features
This motor can be processed by the anticorrosion anti-mould-proof process to derive outdoor (W) and outdoor corrosion protection (WF) motors. High efficiency, energy saving, low vibration, small size, light weight, reliable performance and easy installation and maintenance. The frame is made of steel plate being welded up into form of square tank shape with light weight and firm rigidity. Stator is an outer-press-assembly structure. The stator winding is F grade insulation at the winding's end part being firm banded. The whole stator and rotor has been treated with VPI technology to make stator and rotor with insulation and moisture resistance. Silver brazing is used between rotor coils and between copper strip and coils to ensure the reliability of motor operation.
