The YVF2 series frequency conversion speed regulation dedicated three-phase asynchronous motor is an AC, efficient, and energy-saving speed regulation motor that can be used in conjunction with domestic and foreign frequency converters. This product operates reliably and is easy to maintain. The motor is equipped with a separate axial fan, which has good cooling effect at different speeds. It can be widely used in equipment that requires speed adjustment, such as light industry, textile, chemical, metallurgical, and machine tool industries.

To better respond to climate change, quickly respond to market demand, focus on innovation that improves energy efficiency and reliability, and promote industrial green and low-carbon transformation and sustainable development. On July 1, 2023, Siemens integrated its related businesses in the fields of low to high voltage motors, gear motors, medium voltage inverters, and electric spindles to establish Innometrics GmbH. Yinmengda is headquartered in Nuremberg, Germany, with operations in 49 countries worldwide, 16 factories, and approximately 15000 employees worldwide.
