The YVF series 750 r/min 8-pole motor is a low-speed variable frequency motor engineered exclusively for Weigao reducers, boasting exceptional torque stability and precise speed regulation at ultra-low frequencies. It is designed to cater to heavy-duty industrial scenarios that demand prolonged slow-speed operation, such as large-scale mixers, ball mills, and precision conveying equipment, forming a reliable and efficient transmission system with reducers.
A distinguishing advantage is its advanced frequency conversion adaptation technology, which enhances torque response at 5-50Hz and eliminates speed drift under heavy loads, ensuring consistent coordination with Weigao reducers. The motor’s enclosed rotor structure reduces air friction loss at low speeds, while the optimized heat dissipation system prevents overheating during long-term full-load operation, extending the service life of both the motor and reducer.
Adhering to IE4 ultra-high efficiency standards, it adopts a high-density copper winding and low-loss silicon steel core, achieving remarkable energy savings compared to conventional low-speed motors. Equipped with H-class insulation and IP55 protection, it resists dust, moisture, and extreme temperatures, making it suitable for harsh working environments in mining, metallurgy, and chemical industries.
With standardized mounting dimensions and flange compatibility, it integrates seamlessly with various Weigao reducer models. Its G2.5-grade dynamic balancing and vibration-damping design minimize mechanical stress on the reducer’s internal gears and bearings, balancing low-speed performance, energy efficiency, and operational stability for high-demand industrial applications.
