AW86BLW Series — 86mm BLDC Motor with Precision Planetary Gearbox
The AW86BLW series pairs Apexwell's 86mm-diameter, 48V brushless DC motor with the same HPS90-L1/L2MB precision planetary gearbox used on the AW86BLF series, scaling rated output power from 220W to 785W across five body lengths. This series delivers higher output power than the AW86BLF at comparable body lengths, from the same precision gearbox platform.

HPS90-L1/L2MB Precision Planetary Gearbox Specifications
| Parameter | 1-Stage | 2-Stage |
|---|---|---|
| Reduction Ratio | 3, 4, 5, 7, 10 | 16, 20, 25, 28, 35, 40, 50, 70 |
| Gearbox Length (L1) | 110 mm | 132 mm |
| Rated Output Torque | 39–90 N·m | 70–100 N·m |

Momentary torque moment is rated at two times the rated output torque across both stages. 13 reduction ratios are available in total (3 to 70:1) — identical to the AW86BLF gearbox, since both series share the same HPS90-L1/L2MB platform.
Wiring
Each AW86BLW 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 output power up to 785W, the AW86BLW precision series fits heavy industrial robotic joints, precision rotary index tables, large-format CNC axes, and automated production machinery where more motor power is needed at a similar body length than the AW86BLF offers.
Why Choose the AW86BLW Precision Gearmotor
Backlash as tight as ≤10 arcmin makes this series suitable for applications where positioning repeatability matters more than cost, even at high torque and power levels. Because the gearbox platform is shared with the AW86BLF, a design can move between the two motor variants without changing gearbox dimensions or ratio options. 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. 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.
