ABB 7BA44-9147-5150 Shaft Ground Motors - 250HP,1785RPM

Shaft Grounding design reduces stray shaft current and bearing wear, translating to longer bearing life and lower maintenance costs. In real-world lines with high starting torque and frequent starts, these gains mean fewer unplanned outages and longer intervals between service. This approach is especially beneficial in conveyors, crushers, and heavy-duty pumps where electrical stress can accelerate wear and derail schedules. High horsepower and drive flexibility are core advantages. At 250HP and 1785RPM, with 3PH operation and 6-60Hz compatibility, the motor delivers robust torque across a wide frequency range. This makes it well-suited for variable-frequency drives and process lines that demand precise speed control and reliable starting performance. Rapid availability and standardized configuration reduce procurement risk. Lead time is listed as 0 day, and the design is not made-to-order, ensuring a predictable delivery timeline. Stock is distributed across multiple warehouses, including locations in China and Alabama, United States, supporting regional maintenance strategies. Structural robustness supports challenging environments. The ABB designation indicates a 449T-class frame with a heavy weight of 2888 lb, enabling stable mounting and long service life under vibration-heavy operation. The standard, non-custom configuration simplifies replacement and cross-vendor maintenance. Warranty and service considerations reinforce value. Warranty returns are managed through a straightforward policy, with a focus on accountability and prompt fault resolution. Combined with ABB’s global support network and ready spare parts, this translates to lower total cost of ownership over the motor’s lifecycle. Installation and compatibility readiness are enhanced by stock readiness and broad availability. With in-stock units at multiple warehouses, procurement teams can schedule maintenance windows with minimal disruption and keep critical lines running with confidence.
