Variable frequency electric motors YVF280S-4A-75KW-380V-IC416-B3

Adaptive variable frequency electromagnetic design:The stator core is made from low-loss cold-rolled silicon steel wafers, complemented by a winding design optimized for a wide frequency range. This configuration adapts to variable speed control conditions in the range of 5-50 Hz, effectively reducing iron and copper losses at different rotation speeds.

Special transmission design with variable speed control:The rotor is highly calibrated and dynamically balanced in combination with high quality, low friction rolling bearings (using long life lubricant). This configuration compensates for vibration and mechanical wear over a wide speed range, ensuring stable operation under a variety of speed control conditions.

Improved cooling system:Equipped with a reinforced self-ventilating cooling shroud and a high-performance cooling fan. The airflow design accommodates the variable load and temperature rise characteristics of variable speed engines, quickly dissipating the heat generated at varying speeds and loads. This prevents temperature fluctuations during speed control from affecting the life of the motor.

Outstanding speed control accuracy:Supports smooth, stepless speed control over a wide range of 5-50 Hz, providing high starting torque (1.8 times the rated torque) and highly accurate speed control. Accurately meets the dynamic speed requirements of loads, suitable for applications such as conveyor speed control, variable frequency start/stop for packaging equipment, and flow control for fans and pumps.

Significant energy efficiency and savings:Complies with highly efficient IE3 standards. Combined with variable frequency speed control technology, it provides energy savings of 20-30% compared to traditional throttling methods using valves or dampers. Long-term operation significantly reduces the enterprise's energy costs, which meets the requirements of industrial modernization in the field of energy saving.

High operational stability and reliability:electromagnetic and mechanical losses remain low over a wide frequency range, while the operating noise level is<=85 dB, and the rms vibration speed is<=2.8 mm/s.
