Product Description:

The AKM31H-ANCNC-01 synchronous servo motor is manufactured by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. In automation cells, it converts commanded current into regulated torque and speed for positioning, indexing, and coordinated motion. Its compact frame helps it fit multi-axis platforms that drive pick-and-place heads, small gantries, or metering pumps. This makes it a practical choice for machinery where several servo axes are installed close together.

Electrical connectivity is provided through 2 SpeedTec Ready connectors, with one connector for power and the other for feedback, so cabling locks with a quarter-turn. The motor is supplied without a brake, so static holding torque must be provided by an external device or by the drive when the application permits. Position data come from the integrated SFD sensor, which outputs a 4-line feedback signal for commutation and closed-loop control. The housing uses a 70 mm frame format, and its IEC flange with accuracy grade N supports repeatable alignment when bolted to gearboxes or face-mounted brackets. The mechanical interface uses a smooth shaft to support coupling arrangements that rely on a plain shaft profile.

A permanent shaft seal blocks oil migration and dust along the output journal, supporting installations exposed to coolants or airborne particulates. The encoder provides single-turn inductive feedback, which gives absolute position within one revolution without batteries, and its physical format is classified as size 10/15/21 for compatibility with standard connectorized cable sets. Motor constants are matched to winding code H, so the drive receives the expected voltage and resistance characteristics for accurate current control. Because the rotor length index is 1, the motor uses the shortest magnetic stack in this platform and is well suited to low-inertia applications where fast response is important. This layout supports stable operation in compact motion axes that require precise speed and position control.
