AW42BLY Series — 42mm Brushless DC Motor
The AW42BLY series is Apexwell's 42mm-frame, 24V three-phase brushless DC motor line, built with a 4-pole rotor design across two body lengths. Compared to our 8-pole AW42BLF series in the same 42mm frame, the 4-pole AW42BLY targets applications where smoother low-speed operation matters more than peak torque density — giving OEMs a second motor option on the same mounting footprint.

Typical Applications
The AW42BLY's compact 42mm frame and moderate power range (22W–50W) suit small pumps, fans, office automation equipment, light conveyor rollers, and other continuous-duty mechanisms where a quiet, smooth-running 24V brushless motor is needed in a space-constrained design.
Why Choose the AW42BLY Series
As a 4-pole design, the AW42BLY offers a different commutation profile than higher-pole-count motors in the same frame size, which can translate to smoother torque delivery at lower speeds — useful in applications sensitive to cogging or vibration. Apexwell can configure the AW42BLY 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.
