Product Description:

The AKM22E-BNBNC-00 is manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. It is used in industrial automation to deliver commanded shaft position and speed wherever compact, high-performance rotary motion is required. By combining a permanent-magnet rotor with an integrated sensing system, the motor supplies drive controllers with real-time position data so motion loops can remain accurate during acceleration, steady running, and settling. This makes the unit suitable for compact servo axes that need responsive motion and consistent closed-loop control.

The housing width is only 58 mm, and the compact frame mates to a NEMA flange for installation in standardized mechanical layouts. Power and feedback conductors exit through two SpeedTec Ready connectors, which support quick cable attachment and orderly routing in tight machine spaces. A smooth shaft allows couplings or pulleys to be mounted without keyways, which can help reduce imbalance at high rotational speeds. The motor uses winding code e, and that selection matches the unit to compatible drive voltage and current ranges. The customization level is standard, so the motor is supplied in its regular production configuration rather than with special machining or nonstandard materials.

Control fidelity is supported by the SFD feedback system, which delivers 4 lines of differential digital data to the drive. The measuring element is a single-turn, inductive unit, so the system reports absolute position within one mechanical revolution without relying on battery-backed multi-turn tracking. Feedback sizing follows the manufacturer’s Size 10/15/21 convention, while rotor length index 2 balances torque output against inertia for mid-range servo axes. The motor is supplied without a brake, so any load-holding duty must be handled by the drive or by an external locking device.
