AW86BLF Series — 86mm BLDC Motor with Brake
The AW86BLF series is Apexwell's 86mm-diameter, 48V brushless DC motor line fitted with an integrated holding brake, so the shaft stays locked in position when motor power is removed. Rated output power scales from 130W to 750W across five body lengths, with a standard brake rated at 4.0 N·m of static friction torque, making this the highest-torque frame in Apexwell's BLDC brake-motor platform.

Brake Specifications
| Parameter | Value |
|---|---|
| Static Friction Torque | 4.0 N·m |
| Rated Voltage | DC 24V ±10% |
| Rated Power | 9.2 W |
| Current | 0.385 A |
| Resistance | 62.3 Ω |
| Pull-in Voltage | 20V Max |
The brake holds the motor shaft when de-energized and releases when 24VDC is applied, independent of the motor phase windings. Permanent-magnet brake, spring brake, power-off brake, and power-on brake variants are available as customizations.
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. The brake coil is wired and powered separately.
Typical Applications
With an integrated holding brake on an 86mm frame, the AW86BLF series fits heavy industrial vertical-axis drives, large robotics joints that must hold position when power is removed, lift, hoist, and elevator mechanisms, and other applications where an unpowered axis must not drift or fall under substantial load.
Why Choose the AW86BLF Brake Motor
A holding brake keeps the shaft locked whenever the motor is de-energized — whether from a planned power-down or an unplanned fault — which a BLDC motor's own detent torque cannot guarantee once current is removed. Five body lengths let a product line scale output power nearly 6x (130–750W) while brake spec stays unchanged. Both power-off (fail-safe) and power-on brake logic are available, letting the same motor frame suit different safety requirements. Custom brake torque and connector 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.
