Driving the heart of heavy industry: An in-depth analysis of Sigma YRKKHigh voltage motorsTechnical Advantages and Applications

In the field of modern heavy industry, the efficient operation of equipment and energy saving and consumption reduction are often a pair of contradictions that are difficult to balance. For cement, mining, steel and other industries, how to choose a power equipment that can provide strong starting torque and maintain long-term stable operation under large loads is the key to reduce operating costs. As a leader in the domestic motor manufacturing industry.Xi'an Simo MotorintroducedSigma yrkk motorsseries, with its excellent air-to-air cooling technology and wire-wound rotor design, is becoming the preferred power solution for many large industrial and mining enterprises.

Technical Analysis: Why YRKK Series?

The so-called “YRKK” has a specific technical meaning in the naming of the motor type: Y stands for asynchronous motor, R stands for wound rotor, the first K stands for closed structure and the second K stands for air-to-air cooler. This design allowsSigma yrkk motorsExtremely adaptable in harsh environments.

Compared to a normal squirrel cage motorWound Rotor Designis the core advantage of this series. It allows the user to string a resistor or frequency sensitive varistor in the rotor circuit, thus reducing the starting current while obtaining aHigher starting torque. This feature is critical for equipment requiring heavy-duty startup such as ball mills, crushers, fans and pumps. In addition, its unique air-to-air cooling system (IC611) utilizes the motor's own fan to circulate internal heat through the heat exchanger for cooling, effectively preventing dust and water vapor from entering the motor interior and greatly extending insulation life.

Double guarantee of energy efficiency and stability

In the context of “double carbon”, the energy efficiency ratio of industrial equipment has become a hard indicator.Sigma yrkk motorsCold rolled silicon steel sheet with high magnetic permeability and low loss is used and combined with theSimo motorsThe advanced VPI vacuum pressure impregnation process results in a significant reduction in iron and copper losses during operation of the motor. Data shows that the efficiency of this series of motors in a high voltage (6kV or 10kV) environment can usually be maintained in the94% and aboveThe company has been able to save a considerable amount of money on its electricity bill.

At the same time, in order to cope with the vibration problem during the operation of heavy machinery, Sigma has adopted a high-strength steel plate welded structure in the design of the machine base, and the box-type machine base is not only light in weight, but also has good rigidity, which is able to effectively suppress resonance.

Application Case Study: Power Upgrade for Cement Ball Mills

To gain a more intuitive understandingSigma yrkk motorsThe actual performance, we can refer to a large cement group's technical reform project. The plant originally used an old high-voltage motor, due to insufficient starting torque, in the winter low temperature or full load shutdown after starting again, often appear “boring” phenomenon, and frequently burned the collector ring.

With the introduction of a 2000kW ratedSigma yrkk motorsAfter that, the problem has been fundamentally solved. Thanks to its optimized slip ring system and carbon brush material, the temperature rise on the surface of the collector ring is controlled within the ideal range during frequent starting and long-time running of the motor, completely eliminating the hidden danger of excessive spark. What's more, the starting control cabinet supporting the motor realizes smooth starting and reduces the impact on the power grid by about 30%, which not only guarantees the continuity of the production line, but also reduces the pressure on the capacity increase of the transformer.
