AW70BLF Series — 70mm Brushless DC Motor
The AW70BLF series is Apexwell's 70mm-frame, 48V brushless DC motor line, scaling from 166W to 471W of output power across three body lengths. Sitting between our 60mm and 80mm frames, the AW70BLF fills the gap for applications that need more torque headroom than a 60mm motor offers without stepping up to an 80mm footprint.

Model Comparison
| Model | Rated Torque | Rated Current | Output Power | Peak Torque | Peak Current | Body Length | Mass |
|---|---|---|---|---|---|---|---|
| AW70BLF86-430 | 0.53 N·m | 4.5 A | 166 W | 1.59 N·m | 13.5 A | 86 mm | 1.3 kg |
| AW70BLF116-430 | 1.1 N·m | 9.5 A | 345 W | 3.3 N·m | 28.5 A | 116 mm | 2.0 kg |

Torque constant ranges from 0.112 to 0.115 N·m/A; back-EMF constant ranges from 8.38 to 9.07 Vrms/kRPM. Rotor inertia scales from 0.56 to 1.4 kg·cm² with body length.
Also Available as a Gearmotor
The same AW70BLF motor windings are available factory-fitted with a 2GN-K/5GN-K eccentric gearbox for applications needing higher output torque at lower speed. See our AW70BLF Series — 70mm BLDC Motor with Eccentric Gearbox for reduction ratios and gearbox torque ratings.
Typical Applications
With output power from 166W to 471W, the AW70BLF series suits mid to heavy-duty conveyor drives, industrial fans and pumps, packaging machinery, and robotics base actuators where a 60mm motor doesn't have enough torque and an 80mm frame is larger than the application needs.
Why Choose the AW70BLF Series
The AW70BLF's three body lengths cover a 2.8x power range (166W–471W) on a single 70mm mounting interface, letting a product line scale output without re-qualifying the mechanical design. Apexwell can also configure this motor with an integrated driver or closed loop encoder feedback 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.
