Overview of YVFE5 Series Ultra-high Efficiency Variable-frequency Speed-regulating Three-phase Asynchronous Motors

The YVFE5 series high-efficiency variable-frequency speed-regulating three-phase asynchronous motors are derived from the YE5 series motors and are variable-frequency speed-regulating three-phase asynchronous motors. They comply with GB/T 755 "Rotating Electrical Machines - Rating and Performance". The cooling method is IC416, and their efficiency values are in line with E5 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, YVFE3, and YVFE4 series low-voltage variable-frequency speed-regulating three-phase asynchronous motors.

The speed-regulating system formed by the YVFE5 series ultra-high efficiency variable-frequency speed-regulating three-phase asynchronous motors and the frequency converter, 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.
