Product Description:

The AKM23D-EFB22-00 is a servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. It is designed to deliver closed-loop rotary motion in industrial automation tasks such as indexing tables, pick-and-place axes, and electronic gearing stages. By combining a compact electromagnetic design with an integrated feedback device, this motor provides the position accuracy and speed stability required for tightly coordinated multi-axis systems. It is suited for applications where the controller must command frequent starts, stops, reversals, and synchronized motion without losing repeatability.

A built-in 24 V holding brake keeps the shaft locked whenever the drive is disabled, securing vertical loads during power loss or shutdown. The motor has two front-mounted SpeedTec Ready connectors, and the quarter-turn bayonet style helps simplify power and signal connections in compact installations. Position feedback is provided by a 2048 lines/rev optical system, which yields 8192 quadrature counts per revolution after standard four-times edge evaluation and gives the drive fine motion information for speed and position control. The feedback device is a Comcoder, which supports compatibility with common Kollmorgen drives and keeps encoder integration straightforward. Because the scan head reads a single-turn optical code disk, absolute position is retained within one mechanical revolution without batteries or multirevolution gearing.

The signal electronics use the EPC 15T format, allowing connection with drives that accept this serial data structure and supporting the expected feedback exchange for this motor type. A flange side dimension of 58 mm matches IEC 72 size 58 mounting geometry, so the motor fits common metric mounting patterns and compact machine frames. Magnetic stack thickness is identified as Rotor Length 3, which places the motor in the corresponding continuous torque class for this frame size and affects the motor's axial length. The motor also uses a D winding, which is optimized for 230 V bus drives that require moderate continuous current and high dynamic response. This winding selection helps balance current demand and speed capability in general-purpose servo axes.
