This three-phase synchronous motor is designed for driving fans, pumps, compressors, and other general equipment in industries such as petroleum, chemical, power, metallurgy, and coal. The motor complies with GB755-2000 and IEC standards, offering high efficiency, low noise, low vibration, high reliability, and ease of installation and maintenance. The rated frequency is 50 Hz, with a power factor of 0.9 (leading).
The motor features an IP44 protection level (excluding slip rings), structure and installation type IM7311, cooling methods IC37 or IC91W, and an S1 (continuous) duty cycle. The stator uses F-class insulation treated with VPI vacuum pressure impregnation technology, ensuring excellent insulation performance. Suitable for environments free of acidic and alkaline corrosive gases.
