ABB M2BAX General Performance Low Voltage Cast-Iron Motors
The ABB M2BAX Motor Series (featured model: M2BAX 132SMA4 7.5 kW IE3) is ABB's standard general performance cast-iron low voltage induction motor platform, engineered for high reliability, cost-effective operation, and global industrial versatility. Built with a high-rigidity cast-iron frame structure, IP55 enclosure protection, and Class F temperature insulation (Class B rise margin), M2BAX motors fully comply with **IEC 60034-30-1 IE2, IE3 Premium, and IE4 Super Premium Efficiency** energy standards. Covering power ratings from 0.12 kW to 355 kW across 2-pole, 4-pole, 6-pole, and 8-pole executions (IEC frame sizes 71 to 355), M2BAX motors feature VFD-rated winding insulation for frequency inverter operation with **ABB ACS380, ACS580, and ACS880 drives**. Designed for high interchangeable reliability, ABB M2BAX motors serve as the direct 1-to-1 mechanical replacement for legacy **ABB M2QA** cast-iron motors in industrial pumps, fans, belt conveyors, compressors, and general machinery.
