Siemens 1LA7073-2AA11 Three-Phase Low-Voltage Induction Motor

The Siemens 1LA7073-2AA11 (1LA7073-2AA11) is a low-voltage three-phase squirrel-cage induction motor engineered for industrial drive applications. Belonging to the Siemens 1LA7 motor series within the SIMOTICS family, this compact AC motor provides reliable mechanical power for continuous-duty operation across factory automation, material handling, processing lines, and machine building. Designed with an aluminum housing and self-cooling architecture, the unit operates efficiently with compatible industrial motor starters and variable frequency drives. It delivers robust performance in driving pumps, ventilation fans, compressors, conveyor belts, and general machinery. With a net weight of approximately 10 kg, the motor is built to withstand demanding industrial environments while delivering stable torque and consistent rotational speed. Operating documentation should be consulted to ensure appropriate terminal wiring, mounting orientation, and electrical supply matching prior to commissioning or replacement in existing equipment.
