Short description

YVF series of variable frequency speed regulating high voltage three-phase asynchronous motors is developed by Wolong. When employed in conjunction with a frequency converter, these motors are capable of achieving smooth, stepless speed regulation.

Description

YVF are manufactured using only the highest quality materials and are constructed to the highest standards of precision. These motors offer a wide speed regulation range, high efficiency, low noise, low vibration, safe and reliable operation, convenient use and maintenance, energy saving and environmental protection.

Wolong’s YVF series of motors features different structures with different cooling methods(IC 611, IC616,IC666 and so forth). It offers a number of advantages, including a lower centre height, greater power, higher efficiency, lower noise, safe and reliable operation, and convenient use and maintenance. It is suitable for driving a wide range of mechanical equipment, including ventilators, compressors, water pumps, transportation machinery, general machinery, and other similar devices. When the working speed is adjusted below the rated speed, the energy-saving effect is significant. The series of high-voltage three-phase asynchronous motors can be used in a variety of environments, including indoor and outdoor settings, as well as in plateau and humid/hot climates, and consistently provide excellent driving force.
