Product Description:

The AKM23D-EFCNC-00 is a brushless servo motor produced by Kollmorgen and supplied as part of the AKM Synchronous Servo Motors series. It is intended for closed-loop motion axes that demand exact velocity regulation and repeatable positioning in packaging lines, robotics, and material handling stations. The motor fits applications where compact dimensions and controlled dynamic response are important to overall machine performance. It also serves as a rotary drive option for systems that need accurate motion without adding unnecessary bulk to the axis.

Mechanical and power interfaces are provided through 2 SpeedTec Ready connectors, allowing keyed plug-in mating for both power and feedback without field soldering. The housing has a square face of 58 mm, making the unit suitable for installations with limited mounting space while still supporting the output expected from the AKM size-23 frame. Electromagnetic behavior follows Winding Designation D, which corresponds to a specific voltage constant and thermal profile, and Rotor Length Index 3, which indicates the third core length option for higher torque density. The motor is built without a brake, so holding functions must be provided by the drive or by an external mechanical lock when the axis is stopped.

Position data is carried over 4 lines and is generated by the integrated SFD resolver-based feedback device. This sensor is a single-turn inductive system, so it reports absolute rotor angle within one revolution and relies on drive-side counting for multi-turn information. The sensing head is categorized as Size 10/15/21, matching the connector pitch used on Kollmorgen's feedback bus. The unit is supplied in the standard customization level, so its mechanical dimensions and electrical characteristics follow the base product family.
