Product Description:

The AKM23D-BNBNC-00 is a brushless AC servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. As a compact electromechanical actuator, it delivers controlled torque and speed for positioning tables, pick-and-place axes, and other closed-loop motion systems in automated equipment. Its compact housing makes it suitable for tightly spaced machinery where repeatable motion and stable servo response are required. The AKM family also includes multiple winding, feedback, and mounting options for different duty requirements across automation platforms.

This model is supplied without a brake, so applications that need holding force must use external clamping or drive torque when power is removed. It has a smooth shaft, which simplifies coupling because no keyway alignment is required during assembly. A NEMA flange pattern supports direct attachment to standardized gearheads and fixtures, and electrical connections are made through two SpeedTec Ready connectors with quarter-turn locking. The motor has a frame size of 58 mm, giving it a compact square profile, and it has a standard customization level with catalog-grade mechanical tolerances and finishes.

Closed-loop performance is provided by an SFD feedback assembly that sends 4 lines of digital position data to the drive. The encoder uses a single-turn inductive design, so it reports absolute rotor angle within one mechanical revolution without batteries or gears and offers improved resistance to stray magnetic fields. This feedback type supports stable position reporting in applications that operate near sources of electrical noise. Internal sensing hardware uses size 10/15/21 components that match the motor endbell profile. Drive matching is set by winding code D, which provides a balance of speed and torque for medium-inertia loads, and the rotor length index of 3 increases active iron length for higher continuous torque.
