Long description
This VYBO Electric 3LC-355LX2A-2 three-phase asynchronous electric motor with a power output of 450 kW is a top-of-the-line solution for the most demanding industrial applications. Its robust cast iron construction ensures long life and durability in harsh operating conditions. With an IE3 efficiency class, the VYBO Electric 450kW motor guarantees a significant reduction in operating costs and minimizes the ecological footprint thanks to optimized energy consumption. The motor is equipped with IP55 protection, which means excellent protection against dust and splashing water, and insulation class F, which ensures reliable operation even at higher temperatures. For increased safety and protection of the winding, PTC thermistors are integrated to monitor the temperature and automatically shut down the motor in case of overheating. This feature extends the life of the motor and prevents costly breakdowns. The electric motor is fully compatible with frequency converters and soft starters, allowing for smooth speed control and gentle starting, which reduces mechanical stress and extends the service life of the entire system. Typical applications include the drive of pumps, fans, compressors, conveyors, and other industrial equipment where reliability and high performance are key. The motor bearings are designed for long-term, maintenance-free operation, but for maximum service life, regular inspection and maintenance according to operating conditions is recommended. With a speed of 2985 rpm and a low noise level of 100 dB(A), this motor is the ideal choice for applications requiring high efficiency and reliability.
Powerful VYBO Electric 450kW three-phase electric motor with 2 poles and IE3 efficiency. Robust cast iron construction, IP55 protection and integrated PTC thermistors ensure reliable and long-term operation. Ideal for demanding industrial applications such as pumps, fans and compressors, where high efficiency and low operating costs are key. Long description
