General Use M2BAX IE4 from 71 to 132

General Use M2BAX IE4 motors from frame sizes 71 to 132 represent a significant leap in energy efficiency for low-voltage three-phase induction motors. These units are designed to meet the IE4 Super Premium Efficiency class, drastically reducing energy losses compared to older IE2 or IE3 models. The M2BAX series typically features a cast iron frame for sizes 100 and above, with aluminum frames for the smaller 71, 80, and 90 sizes, ensuring robust mechanical strength and effective heat dissipation. Key technical parameters include rated power outputs ranging from 0.25 kW up to 7.5 kW, with standard pole configurations of 2, 4, 6, and 8 poles, covering synchronous speeds from 3000 to 750 rpm. Operating voltages are commonly 230/400V or 400/690V at 50 Hz, with a degree of protection IP55 as standard, making them suitable for dusty and humid environments. The insulation class is typically F with a B temperature rise, providing a thermal reserve for demanding cyclic loads. These motors are also known internationally as high-efficiency induction motors, premium efficiency AC motors, or IE4 squirrel cage motors.

These IE4 motors are engineered for continuous duty (S1) applications across a wide spectrum of industrial sectors. They are the prime movers in pumping systems for water treatment, HVAC, and irrigation, where energy savings directly impact operational costs. In the material handling sector, they drive conveyor belts, hoists, and crushers. They are also extensively used in compressors, fans, and blowers for ventilation and pneumatic systems. Their compact design and high torque characteristics make them ideal for integration into machine tools, textile machinery, and food processing equipment. The M2BAX series is particularly suited for installations within electrical panels and motor control centers (MCCs) when paired with variable frequency drives (VFDs) for precise speed control, though it is critical to ensure the motor's insulation system is compatible with inverter-fed operation.

Within the M2BAX IE4 range from frame 71 to 132, the primary subcategories are defined by frame size and pole count. For example, the M2BAX 71 series includes models like the M2BAX 71MA2 (0.25 kW, 2-pole) and M2BAX 71MB4 (0.37 kW, 4-pole). Moving up, the M2BAX 80 series offers the M2BAX 80MA2 (0.75 kW, 2-pole) and M2BAX 80MB4 (0.75 kW, 4-pole). The M2BAX 90 series includes the M2BAX 90SA2 (1.5 kW, 2-pole) and M2BAX 90LB4 (1.5 kW, 4-pole). For the M2BAX 100 series, common codes are M2BAX 100LA2 (3 kW, 2-pole) and M2BAX 100LB4 (3 kW, 4-pole). The M2BAX 112 series features the M2BAX 112MA2 (4 kW, 2-pole) and M2BAX 112MB4 (4 kW, 4-pole). Finally, the M2BAX 132 series includes the M2BAX 132SA2 (5.5 kW, 2-pole) and M2BAX 132SB4 (5.5 kW, 4-pole). The part number structure typically follows the pattern: M2BAX [Frame Size] [Mounting Code] [Pole Count], where the mounting code indicates the shaft height and mechanical configuration.
