AW60BLF Series — 60mm Closed Loop BLDC Motor
The AW60BLF series is Apexwell's 60mm-frame, 48V closed loop brushless DC motor line, built with an integrated 1000 CPR encoder for real-time position and speed feedback. Offered across four body lengths from 78mm to 141mm, the series scales from 100W to 400W of output power within the same mounting footprint — giving engineers headroom to size up torque without re-qualifying a new mechanical interface.

Torque constant ranges from 0.094 to 0.116 N·m/A; back-EMF constant ranges from 8.01 to 8.88 Vrms/kRPM across the series. Rotor inertia scales from 0.31 to 1.01 kg·cm² with body length.
Closed Loop Feedback
Every AW60BLF motor integrates a 1000 CPR encoder as standard, allowing the driver to continuously compare commanded position against actual rotor position and correct in real time. This eliminates the risk of undetected position error under variable or peak load — the peak torque column above shows up to 3x the rated torque is available for short bursts without losing sync, which a standard open-loop BLDC cannot guarantee. Optical, magnetic, and resolver encoder options are also available for custom resolution or absolute-position requirements. (Closed loop feedback is becoming the default choice across motor types for exactly this reason — see our analysis of why closed loop steppers are replacing traditional steppers for the broader trend driving this shift.)
Typical Applications
With power scaling from 100W to 400W and closed loop position accuracy, the AW60BLF series fits robotics joints, industrial conveyor and packaging drives, collaborative robot actuators, and NEV auxiliary systems — applications where load can vary unpredictably and a missed step or stall is not acceptable.
Why Choose the AW60BLF Series
Standardizing on the AW60BLF series lets a single mounting and control interface cover a 4x power range (100W–400W), reducing qualification effort as a product line scales. The built-in 1000 CPR encoder means closed loop control is available out of the box, without sourcing and integrating a separate feedback device. Apexwell can also configure any model with a gearbox or holding brake for load-holding applications.
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.
