Abb M3aa 160 L 2 Three Phase Induction Motor Nameplate Appraisal

ABB M3AA 160 L-2 Three-Phase Induction Motor Nameplate

This is a metallic manufacturer's nameplate for an ABB industrial electric motor, specifically model M3AA 160 L-2. The plate is rectangular, constructed from durable etched or stamped aluminum, and is secured to the motor housing with four rivets. It features a technical data grid providing specifications for various voltage inputs (380V to 690V) and frequencies (50Hz to 60Hz). Notable technical markings include a power rating of 18.5 kW to 21.00 kW, speeds up to 3510 r/min, and an IP55 protection rating. The plate displays the 'ABB Motors' branding, the CE mark, and manufacturing codes such as 'Prod. code: 3M16L02AD07001' and 'No. 50416R3 500 /2'. Structurally, the plate shows significant signs of industrial wear, including surface grime, oil staining, and slight corrosion around the edges and rivets. The surrounding cast-iron motor fins are visible, showing a dark, weathered patina and remnants of blue-grey paint. This component is essential for identifying the electrical and mechanical requirements of the underlying high-performance industrial equipment, likely dating from the early 2000s based on the IEC 60034-1 standard reference.
