Siemens 1LA8 280-100L 07 Three-Phase AC Induction Motor

The Siemens 1LA8 280-100L 07 is a robust and reliable 3-phase AC induction motor designed for continuous-duty industrial applications. Manufactured in Germany, this motor delivers up to 75 kW of power with a standard operating speed of 1480 RPM at 50 Hz. Featuring a power factor between 0.83 and 0.86, the motor ensures efficient energy usage. It supports a 3 x 400 V power supply and offers excellent protection with an IP54 rating and B-class insulation. Built in B3 mounting configuration, the motor is cooled using the IC411 (TEFC) method, ensuring minimal maintenance and long service life. High-quality bearings (NU217 at the drive end and 6317 at the non-drive end) and reliable lubrication using DIN 51825-K3K grease make it ideal for demanding operating conditions.
