75kW electric motor 1485 rpm IE3 – VYBO Electric 3LC-280S-4

The VYBO Electric 3LC-280S-4 electric motor with a power output of 75 kW and 4 poles is designed for maximum reliability and energy efficiency. With an IE3 efficiency class and a rated speed of 1485 rpm at 50 Hz, this motor minimizes operating costs. It features a robust 280 mm cast iron frame and IP55 protection, which guarantees protection against dust and splashing water, making it suitable for demanding industrial environments. Insulation class F ensures high thermal resistance. The technical parameters underline its performance: the starting torque ratio (LRT/RLT) is 2, the maximum torque ratio (BDT/RLT) reaches 2.2, and the starting current ratio (LRA/RLA) is 7. The rotor’s moment of inertia is 1.855 kg/m², which contributes to stable operation. The motor is equipped with high-quality 6317-C3 bearings on both the drive side (DE) and the non-drive side (NDE), ensuring long life and minimal maintenance. The noise level is maintained at 85 dB(A) and the total weight of the motor is 640 kg. Integrated PTC thermistors provide additional protection against overheating. The motor is fully compatible with frequency converters and soft starters, allowing flexible speed control and smooth start-up. It is ideal for applications such as pumps, fans, compressors, conveyors, and other machinery requiring reliable and efficient drive.
