Product Overview

The AIMIN YVF series, manufactured by Xi'an AIMIN Motor Co., Ltd., are purpose-built variable-frequency three-phase asynchronous motors designed for precise speed control and high-efficiency industrial applications. Engineered to comply with IEC 60034 and GB/T 755 standards, these motors (including models like the YVF355L2-8A 220kw motor shown) feature optimized electromagnetic design and robust mechanical construction to deliver reliable performance when paired with variable frequency drives (VFDs).

With a power range spanning from low to medium capacities (including models like the YVF355L2-8A 220kw motor shown), the series supports a wide frequency range of 5–100 Hz, enabling stepless speed regulation. Class 155 (F) insulation systems and reinforced winding protection ensure resistance to high-frequency voltage pulses, extending service life under VFD operation. The IP55 enclosure rating, combined with IC416 forced ventilation cooling (independent cooling fan), guarantees consistent thermal management across the entire speed range, even during low-speed constant-torque operation.

Key mechanical features include high-grade bearings (e.g., NU322, 7322) and cast iron frames, reducing vibration and noise while enhancing durability. Available in multiple mounting configurations (IM B3, IM V1, etc.), these motors are ideal for pumps, fans, conveyors, and processing machinery in industries such as metallurgy, mining, and chemical processing. The series (take YVF355L2-8A 220kw motor as model) offers significant energy savings, precise process control, and compliance with CE certification, making it a trusted solution for demanding variable-speed applications worldwide.
