Long description
Introducing the robust and highly efficient VYBO Electric 4LC-315S-8 electric motor with a power output of 55 kW, designed for demanding applications in the oil and gas industry. This 8-pole motor with a 315 frame and 740 rpm provides maximum torque at minimum speed, which is key to reliable operation in critical environments. With an IE4 Super Premium Efficiency rating, the motor achieves 93.7% efficiency, ensuring significant reductions in operating costs and minimizing the environmental footprint. It is ideal for pump drives in oil pipeline transport, where continuous and trouble-free operation is required.
Thanks to its robust cast iron frame, the motor is resistant to aggressive media and extreme conditions typical of refineries and natural gas distribution stations. 6319-C3 bearings on both sides ensure long life and reliability. With a noise level of only 82 dB and a power factor of 0.8, this motor is optimized for efficient and quiet operation. Its applications also include natural gas compressor drives, mixers in oil storage tanks, fans in refinery cooling systems, and conveyors in oil processing, where its low speed and high torque deliver optimal performance and reliability.
The VYBO Electric 4LC-315S-8 electric motor with a power output of 55 kW and IE4 Super Premium Efficiency class is a top-of-the-line solution for industrial applications. This 8-pole motor operates at 400V with a speed of 740 rpm, achieving an efficiency of 93.7% and a power factor of 0.8. It is designed for reliable and energy-efficient operation with current optimized for the given power. Long description
