Product Description:

The AKM23D-EFCNR-00 is a servo motor manufactured by Kollmorgen in the AKM Synchronous Servo Motors series. Designed for integration with digital servo drives, the unit delivers controlled torque and precise rotary positioning required in packaging machines, small robotics, and material-handling cells. Its permanent-magnet synchronous construction supports rapid acceleration and tight velocity regulation, enabling coordinated multi-axis motion within a compact footprint. This layout is well suited for axes that need repeatable starts, stops, and short positioning moves throughout continuous machine cycles.

Mechanical interfacing begins with a flange width of 58 mm, which aligns with IEC-58 mounting patterns for consistent installation on compatible machine faces. The electromagnetic circuit is matched to a D winding, indicating voltage constant and current ratings compatible with mid-range bus voltages used on AKD drives. A rotor length index of 3 indicates the stack height that increases continuous torque without altering the shaft diameter. For cabling, the housing carries 2 SpeedTec Ready connectors, one for power and one for feedback, so shielded leads can be locked with a quarter-turn. Position and velocity information is generated by an integrated resolver that withstands high vibration and wide temperature swings while still providing rotor position data to the drive.

The feedback system offers 2-pole resolution, giving the drive two electrical cycles per mechanical revolution for commutation. Because the device supplies single-turn inductive feedback, no internal battery is required, and the feedback package remains simple. Motion safety features must be provided externally because the motor is supplied without a brake, so any load holding during power loss depends on the drive or a mechanical lock. The device is delivered with standard customization, so it follows standard dimensions and ratings, and its feedback head uses the Size 10/15/21 format used across the product family.
