Long description
The high-performance 250kW IE3 electric motor VYBO Electric 3LC-355L2-6 is a top-of-the-line solution for the most demanding industrial applications where reliability and stability are key. With a 6-pole design and a speed of 990 rpm, this motor is designed for the efficient drive of large rotating masses, which is essential in industries such as gas works, oil refineries, cement plants, and steel mills. Its robust construction with a 355 frame and a weight of 1826 kg ensures long life and durability in extreme conditions. The motor is characterized by a high efficiency of 95.8%, which contributes to lower operating costs and compliance with strict energy standards. Low noise levels of 85 dB ensure a more comfortable working environment. An important technical parameter is the optimized rotor inertia, which allows for smooth and controlled starts even for the largest equipment. The 6322-C3 bearings on both sides (DE and NDE) guarantee reliability and minimal maintenance. This electric motor is the ideal choice for driving main compressors, large pumps and grinding mills, where stable performance at low speeds and the ability to handle high loads are required.
