FAQs
When installing the ABB 3GJM282220-ADG, ensure the top termination box is accessible for service, and prepare for the heavy 785 kg net (805 kg gross) with a 280 frame. Plan foundation and crane access to support the large cast-iron frame and 6316/C3 bearings, and align for proper cooling and ventilation at 40 °C ambient and up to 1000 m altitude.
Yes. The motor features Exdb flameproof protection and IP66 sealing, making it suitable for mining and other hazardous locations. It also carries IC411 insulation and IE2 efficiency, supporting regulatory compliance for hazardous-area installations while delivering reliable torque and uptime in demanding operations.
The motor is designed for continuous S1 duty with a 4-pole configuration. It operates at IE2 efficiency, with full-load efficiency around 94.7% and partial-load values near 94.9% at 75% and 94.2% at 50%. Voltage is coded as D, and it supports continuous operation under ambient temperatures up to 40 °C and altitude up to 1000 m.
A robust 280 frame with cast-iron construction, 6316/C3 bearings, and IMB3 IM1001 mounting class contribute to long life and predictable performance. The top-termination box improves service access, while IP66 protection guards against dust and water ingress. These features reduce unplanned downtime and simplify routine maintenance in heavy industry.
This motor excels in mining, cement, and metal-processing environments that require flameproof protection and rugged construction. With Exdb protection, high IP66 sealing, and a heavy-duty frame, it is ideal for conveyors, grinding mills, crushers, and other continuous-duty equipment in harsh, explosion-prone facilities.
