AW42BLF Series— 42mm BLDC Motor
The AW42BLF series is Apexwell's 42mm-frame, 24V three-phase brushless DC motor line, offered across four body lengths so engineers can scale output power without changing the mounting footprint. All four models share the same 24V rated voltage, 4,000 RPM rated speed, 8-pole/3-phase construction, and ball-bearing output shaft — torque and power scale simply by selecting a longer body length within the same series.

Torque constant ranges from 0.035 to 0.0376 N·m/A; back-EMF constant ranges from 2.45 to 2.74 V/kRPM across the series.
Typical Applications
With a compact 42mm frame and output power from 26W to 105W, the AW42BLF series suits space-constrained equipment such as small pumps, cooling fans, office automation, medical carts, and light-duty conveyor rollers — applications where a 24V brushless motor needs to fit inside a tight enclosure while still offering headroom to scale power within the same mounting footprint.
Why Choose the AW42BLF Series
The 42mm frame is one of the most widely adopted footprints for compact automation, making the AW42BLF series a practical fit for OEM designs that need to source multiple power levels without re-qualifying a new mechanical interface each time. Apexwell can configure any model in the series with an integrated driver, gearbox, or custom lead-wire length to match your installation.
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.
