Product Description

YR,YRKS,YRKK 710-1000 6KV/10KV large boxed type Y series asynchronous slip ring motor are the latest products designed and developed according to relevant national and professional standards in combination with our experiences on design and manufacturing high voltage three phase asynchronous motors for more than 60 years through our introduction and digestion of a full set of design and manufacturing technologies of high voltage motors from USA Westinghouse Electric, Swiss ABB and Germany AEG.

This series of motors are made of new materials. They feature such advantages as high efficiency, low vibration, low noise, reliable performance, light weight, easy installation and maintenance.etc.

The power rating, installation dimensions and electrical performance of this series of motors comply with national standard GB T755 Rotating electrical machines rating and performance and GB T13957 technical requirements for the fundamental series of three phase large asynchronous motor, as well as international standard IEC.

Scope of Application

This series of motors can be applied as the driving power for various of general machinery like compressor, ventilator, water pump, crusher and other mechanical equipment, they are widely used in mining, petrochemical, metallurgical industries, power plant .etc as prime motors.

1, Altitude: up to 1000m;
2, Ambient temperature: -15~40°C;
3, Operation duty: S1;
4, Rated Voltage: 3kv,3.3kv,6kv,6.6kv
5, Encloseure protection: IP55(IEC34-5)
6, Cooling method: IC411(IEC34-6)

7,The working voltage change range is not more than ±5% of the rated voltage.

8, No. Of poles: 4,6,8

If there are special conditions and requirements, the order is also acceptable, but an additional technical requirements should be concluded,e.g non-standard power or the power not listed in sample, voltage, frequency, installation dimension, over-all dimension, high altitude, special ambient temperature, ambient environment and corrosive gas, large rotational inertia, strong over-load capacity.etc.
