IEC Standard/ GOST Standard Medium Voltage Electric Motors/Asynchronous Motors 

Y A4, YKKDAZO series high-voltage three-phase asynchronous motor frame size 3551120mm is a series of products developed by our company by introducing, absorbing and digesting advanced technology at home and abroad, adopting modern advanced field analysis technology for electromagnetic calculation, and making fine calculation and optimal design for various losses, wind resistance and strength of each component of the motor. The series of products are developed through mature and reliable design and production system, combined with the company's over seventy years of experience in manufacturing medium and large high-voltage AC motors; the manufacturing of high-quality materials and scientific processing technology, so that it has the advantages of high efficiency, low noise, low vibration, high reliability and easy installation and maintenance.

The series products are mainly used in general mechanical equipment such as fans, pumps, compressors, crushers, chip machines, transportation machinery or other similar mechanical equipment in petroleum, chemical, coal, power station, metallurgy, transportation, textile, pharmaceutical and grain processing industries.

 

II. Advantages and characteristics

1.After absorbing and digesting the advanced technology at home and abroad, the company uses the field and circuit combination method for electromagnetic design of this series, which improves the calculation accuracy of electromagnetism and can provide accurate maximum torque multiplier, and the overload capacity of the motor is effectively guaranteed. Using FEM mechanical analysis method for structural design, and constantly verified by practice, can accurately apply boundary conditions to the established mechanical model, thus solving the accuracy of the use of materials, control the vibration and noise of the motor; at the same time, FEM mechanical analysis method is applicable to various cooling methods, high accuracy and intuitive air volume distribution, improve the level of temperature rise calculation in motor design, reduce ventilation losses, and improve motor efficiency.
