AW57BLF Series — 57mm BLDC Motor with Eccentric Gearbox
The AW57BLF series pairs Apexwell's 57mm-frame brushless DC motor with a 2GN-K eccentric gearbox, giving OEMs a single compact package that delivers gearmotor-level torque without sourcing and aligning a separate reducer. Four motor body lengths combine with reduction ratios from 3:1 to 250:1, covering light-duty positioning through high-torque, low-speed drive applications.

| Max Permissible Torque | 1.2–5.4 N·m | 7–24.5 N·m |
22 reduction ratios available (3, 3.6, 5, 7.5, 9, 10, 12.5, 15, 18, 20, 25, 30, 36, 50, 60, 75, 90, 100, 120, 150, 180, 250:1). Max permissible torque plateaus at 24.5 N·m from ratio 60:1 upward.
Typical Applications
The AW57BLF gearmotor fits applications needing high torque at low output speed in a compact envelope — packaging equipment indexing, valve actuation, conveyor drives, and industrial automation stations where a direct-drive BLDC motor alone can't deliver enough torque without an oversized frame.
Why Choose the AW57BLF Gearmotor
Integrating the 2GN-K eccentric gearbox at the factory means output shaft alignment and gear mesh are pre-set and tested, removing a common source of field assembly error. With 22 reduction ratios available across the same motor frame, one motor selection can be tuned to a wide range of speed/torque targets without changing the base electrical design.
We can customize the electrical parameters of the motor and geometric dimensions such as the motor output shaft size according to customer requirements. Accessories including pulleys, eccentric gearboxes, planetary gearboxes and encoders can also be added.
