AW57BLY Series — 57mm BLDC Motor with Worm Reduction Gearbox
The AW57BLY series pairs Apexwell's 57mm-diameter, 4-pole brushless DC motor with the same NMRV030 worm reduction gearbox used on the AW57BLF series, scaling rated output power from 17W to 140W across five body lengths at 24V or 48V nominal voltage. This is the lower-power tier of Apexwell's 57mm BLDC worm-gear platform, sized for lighter loads than the 8-pole AW57BLF.

Note the nominal voltage steps up from 24V to 48V at the 95mm body length. Torque constant ranges from 0.039 to 0.061 N·m/A; back-EMF constant ranges from 3.91 to 4.68 Vrms/kRPM. Rotor inertia scales from 68 to 268 g·cm² with body length.
NMRV030 Worm Reduction Gearbox Specifications
| Parameter | Value |
|---|---|
| Reduction Ratio | 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100 |
| Gearbox Length (L1) | 95 mm |
| Max Torque Moment | 15 N·m |
| Transmission Efficiency | 60% |
| Weight | 1.2 kg |
Eleven reduction ratios are available (7.5 to 100:1) on a fixed gearbox footprint — identical to the NMRV030 used on the AW57BLF, since both series share the same gearbox platform. Max torque moment, length, and weight stay constant across the entire ratio range.
Wiring
Each AW57BLY motor exits with a 3-wire star-connected power cable for the U/V/W windings and a separate Hall sensor cable (+5VDC, GND, HU, HV, HW) at a 120° Hall electrical angle for standard 6-step commutation.
Typical Applications
With a right-angle output and reduction ratios up to 100:1, the AW57BLY worm-gear series fits light gate and door actuators, small valve and damper drives, tilt mechanisms, and other applications where a 90° direction change saves space and the AW57BLF's power range is more than the application needs.
Why Choose the AW57BLY Worm Gearmotor
The right-angle output lets the gearbox change direction in the mechanical layout without an additional bevel or belt stage, and worm gearing at higher reduction ratios typically resists being back-driven by the load — useful in lifting, tilting, or holding applications where position needs to stay put if power is lost. Because the gearbox platform is shared with the AW57BLF, a design can move between the two motor variants without changing gearbox dimensions or ratio options. For applications needing more power at a similar body length, see the AW57BLF worm-gear series, an 8-pole motor on the same gearbox platform. 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.
