Product Description:

The AKM44J-ANCNDB00 synchronous servo motor is part of the AKM Synchronous Servo Motors series from Kollmorgen. This brushless rotary unit supplies tightly regulated torque, speed, and position control for automated pick-and-place stations, packaging axes, and general-purpose gantries. By pairing with a digital drive, it converts commanded current into proportional electromagnetic torque, making it a practical actuator wherever high cycle rates and repeatability are critical.

It is equipped with 2 SpeedTec Ready connectors, so separate power and feedback leads lock in place with a quarter-turn rather than threaded couplings. The output shaft is a smooth shaft, simplifying the use of compression or shrink-fit couplings and avoiding keyway fatigue. A frame size of 84 mm places the motor in size class 4, establishing its bolt circle and pilot diameter. The assembly ships without a brake, meaning static load holding must be managed by the drive or an external mechanical lock. Coil geometry identified by the J winding sets the resistance and inductance values that match medium-voltage servo amplifiers, while the rotor length index 4 increases continuous torque compared with shorter stacks.

Motion feedback is delivered at 512/2048 lines/rev, supplying the controller with high interpolation capacity for smooth low-speed motion. The sensing element is an EnDAT 2.1 encoder, which streams absolute position, temperature, and status data over a single differential pair. Its multi-turn optical feedback stores revolution counts in a nonvolatile manner, so the axis can recover absolute position immediately after power is restored. The internal scanning head follows the EQN1125/1325 format for compatibility with Kollmorgen AKD drives. An IEC flange with accuracy N tolerance maintains precise concentricity when the motor is bolted to gearboxes or machine frames, supporting repeatable alignment during high-speed operation.
