AW57BLF Series — 57mm Brushless DC Motor
The AW57BLF series is Apexwell's 57mm-frame, 8-pole brushless DC motor line, scaling from 62W to 250W of output power across four body lengths. The first three models run on 24V, while the largest (122mm) steps up to 48V — giving OEMs a torque and power range wide enough to cover light-industrial through mid-power drive applications on a single 57mm mounting footprint.

Torque constant ranges from 0.047 to 0.107 N·m/A; back-EMF constant ranges from 4.08 to 9.04 Vrms/kRPM. Rotor inertia scales from 184 to 602 kg·cm² with body length.
Typical Applications
With power scaling from 62W to 250W, the AW57BLF series fits conveyor and pump drives, industrial fans, packaging equipment, and general automation stations where a compact 57mm brushless motor needs enough headroom to cover multiple power tiers without changing the mechanical interface.
Why Choose the AW57BLF Series
Standardizing on the AW57BLF series across a product line lets a single 57mm mounting and connector interface cover a 4x power range (62W–250W), reducing qualification effort as designs scale up. Apexwell also offers this same motor with an optional 2GN-K eccentric gearbox for applications needing higher output torque at lower speed — see our <a href="#">AW57BLF gearmotor series</a> for details. Custom shaft, encoder, and lead-wire configurations are available on request.
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.
