AW57BLY Series— 57mm BLDC Motor-Economical Version
The AW57BLY series is Apexwell's 57mm-frame, 24V three-phase brushless DC motor line, offered across five body lengths to match a wide range of torque and power requirements without changing the mounting footprint. All five models share the same 24V rated voltage, 3,000 RPM rated speed, star (Y) winding configuration, and Class B insulation — engineers can scale up torque and power simply by selecting a longer body length within the same series.

Rated speed is 3,000 RPM across all five models. Torque constant ranges from 0.052 to 0.063 N·m/A; back-EMF constant ranges from 3.8 to 6.6 V/kRPM.
Typical Applications
With torque scaling from light-duty (17W) to industrial-duty (140W) within a single 57mm frame footprint, the AW57BLY series suits conveyor drives, pumps, fans, packaging equipment, and general industrial automation where a design may need to scale power output later without redesigning the mounting interface.
Why Choose the AW57BLY Series
Standardizing on one series across a product line reduces qualification effort — mechanical mounting, connector interface, and control electronics stay consistent while torque and power scale with body length. All AW57BLY motors are available with optional integrated drivers, gearboxes, and holding brakes for applications requiring load-holding at standstill.
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.
