BEIDE YVF2 Series Variable Frequency Speed Regulation Special Three-Phase Asynchronous Motor

BEIDE’s YVF2 series is a high-performance three-phase asynchronous motor dedicated to variable frequency speed regulation, meticulously engineered to comply with JB/T 7118-2014 and GB/T 14711-2013 standards, paired with IP54 protection rating. As a flagship specialized model for inverter-driven systems, it effectively addresses harmonic interference and low-speed heat accumulation—core challenges of frequency conversion operation—delivering precise speed control, stable performance, and excellent energy efficiency, making it a pivotal component in industrial automation and smart production lines.

Equipped with an F-class insulation system reinforced by vacuum pressure impregnation (VPI) technology, the motor resists electrical stress from inverter-generated PWM voltage waveforms, ensuring reliable high-frequency operation. An independent forced ventilation fan solves low-speed heat dissipation issues, maintaining stable temperature rise even during long-term 5Hz operation and preventing insulation aging. Its housing, made of high-strength cast iron or aluminum alloy (by frame size), boosts rigidity, reduces harmonic-induced vibration, and controls noise below 75dB(A), meeting GB/T 10069.3-2008 noise limits.

Covering frame sizes 80 to 355 (in line with industry standard specifications), the YVF2 series operates at 380V/400V low voltage, with power ranging 0.75kW to 315kW and 2-8 pole options. It enables 5-120Hz stepless speed regulation, achieving constant torque at 5-50Hz and constant power at 50-120Hz. Optimized electromagnetic design minimizes stator-rotor resistance and harmonic copper loss, while precision-machined rotors ensure smooth startup and 150% overload capacity for 60 seconds, adapting to sudden load fluctuations.

Widely used in pumps, fans, conveyors, packaging machinery, and precision machining, it is fully compatible with V/F and vector control inverters, supporting 0-10V/4-20mA analog control and RS-485 communication. Multiple mounting modes (IMB3/IMB5/IMB35) enable flexible integration, while standardized dimensions simplify installation and maintenance. Backed by BEIDE’s strict quality control and comprehensive after-sales service, it offers a durable, energy-saving solution, aligning with global industrial automation and green manufacturing trends.
