AW86BLF Series — 86mm BLDC Motor with Precision Planetary Gearbox
The AW86BLF series pairs Apexwell's 86mm-diameter, 48V brushless DC motor with an HPS90-L1/L2MB precision planetary gearbox, scaling rated output power from 130W to 750W across five body lengths. With two gear-train stages, 13 total reduction ratios from 3:1 to 70:1, and up to 100 N·m of rated output torque, this is the highest-torque frame in Apexwell's precision BLDC planetary-gearmotor platform.

Wiring
Each AW86BLF motor exits with a 3-core sheathed power cable for the U/V/W windings and a separate 5-core shielded Hall sensor cable (+5VDC, GND, HU, HV, HW) at a 120° Hall electrical angle for standard 6-step commutation.
Typical Applications
With backlash as tight as ≤10 arcmin, an IP54 protection rating, and gearbox torque up to 100 N·m, the AW86BLF precision series fits heavy industrial robotic joints, precision rotary index tables, large-format CNC axes, and automated production machinery where high torque and positioning repeatability are both required.
Why Choose the AW86BLF Precision Gearmotor
Backlash as tight as ≤10 arcmin makes this series suitable for applications where positioning repeatability matters more than cost, even at the highest torque levels in Apexwell's BLDC planetary lineup. The IP54 rating and -20°C to +150°C working range extend where the gearbox can be used compared with an open, standard-tolerance planetary unit, and a 20,000-hour rated life supports continuous-duty applications. Thirteen reduction ratios across two gear-train stages let torque and speed be tuned within a single mounting footprint. Custom shaft configurations and encoder feedback 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.
