Brook Hansen M138974 Gearmotor

Brook Hansen M138974/12 Gearmotor is a compact 10FR-frame gearmotor that outputs 30 rpm from a 575 V AC, three‑phase supply and is rated at 1/4 horsepower. This integrated drive pairs a Brook Hansen motor with a reduction gearbox in a single package, delivering high torque at a slow, controllable speed in a compact footprint. The M138974/12 designation identifies this exact gearhead configuration within the Brook Hansen catalog, with the 10FR frame specifying the standard form factor used for industrial gearmotors. Designed for 575 V‑AC three‑phase service, it requires appropriate protective devices and drive electronics compatible with high-voltage, three-phase operation. The combination of a low output speed with a quarter-horsepower rating provides a balance of torque and speed suitable for equipment where precise, steady motion is required and space is at a premium. When selecting a replacement or spare, confirm the exact model (M138974/12) and ensure compatibility with your mounting footprint, shaft arrangement, and electrical input characteristics within your system.
