125HP, 1785RPM, 3PH, 60Hz performance translates to strong start-up torque and reliable running in heavy-duty drives. This supports applications like material handling conveyors and machine tools by reducing startup shocks and improving process stability. Brake integration enables controlled stopping, which cuts wear on mechanical components and enhances line safety during automated cycles. The built-in braking capability helps meet safety standards and reduces risk of accidental reversals, especially on high-inertia loads. Stocking at multiple warehouses shortens lead times, enabling rapid project delivery and less on-site downtime. Compatibility with standard 444T frames and common ABB designations simplifies retrofits and new installations, while the 125HP class delivers predictable, scalable performance for expanding production lines.

FAQs
The ABB designation includes 444T in the model family, indicating compatibility with common 444T frame baselines. However, the data shows the Frame Size as Undefined, so verify mounting pattern, shaft dimensions, and connector layout with your distributor before procurement. When matched, these brake motors retrofit smoothly into many existing drives and motor housings, reducing integration risk.
This brake motor delivers 125 horsepower with a nominal speed of 1785 RPM under 60 Hz, three-phase electrical input. These ratings translate to strong torque during start-up and stable operation in demanding load profiles, making it well-suited for high-inertia conveyors and machine tools that require precise speed regulation and reliable braking performance.
Yes. The combination of high horsepower, integrated braking, and 60 Hz three-phase operation makes it ideal for conveyors, presses, and other automation lines. The built-in brake supports controlled stops, reduces wear on drives, and improves line safety during automated cycles, while compatibility with common frame sizes simplifies integration into existing systems.
The provided data does not list specific certifications. For global deployment, verify CE marking, UL/CSA (where required by your region), and IP protection levels with the supplier based on your application environment. Certification status often depends on the final configuration, accessories, and enclosure used in the install.
Maintenance typically focuses on brake wear components, bearing lubrication schedule, and electrical connector integrity, with warranty terms stating that warranty returns apply if issues arise. ROI benefits come from reduced downtime due to safer, more reliable stops, lower wear on mechanical systems, and faster project deployment thanks to multi-warehouse stocking and readily available spare parts.
