Model Explanation of YVFE4 Series High-efficiency Variable-frequency Speed-regulating Three-phase Asynchronous Motors

?
Overview of YVFE4 Series High-efficiency Variable-frequency Speed-regulating Three-phase Asynchronous Motors The YVFE4 series high-efficiency variable-frequency speed-regulating three-phase asynchronous motors are derived from the YE4 series motors. They are variable-frequency speed-regulating three-phase asynchronous motors and comply with GB/T 755 "Rotating Electrical Machines - Rating and Performance". The cooling method is IC416, and their efficiency values are in line with IE4 in GB/T 32891.2 - 2019 "Efficiency classification of rotating electrical machines (IE code) - Part 2: Variable-speed alternating-current motors". This series of products can completely replace the YJTG, YVF2, YVFE2 and YVFE3 series low-voltage variable-frequency speed-regulating three-phase asynchronous motors. The speed-regulating system composed of the YVFE4 series high-efficiency variable-frequency speed-regulating three-phase asynchronous motors and the frequency conversion device, compared with other speed-regulating methods, has remarkable energy-saving effects, good speed-regulating performance, a wide speed-regulating range, low noise, small vibration, and can be matched with various domestic and foreign frequency converters. It is often used for loads such as fans, pumps, compressors and heating equipment.
