AKM44J-ANCNDB00 Kollmorgen
Wake Industrial LLC is not an authorized distributor of this product.
The AKM44J-ANCNDB00 is a standard servo motor from Kollmorgen, part of the AKM Synchronous Servo Motors series. It uses an EnDAT 2.1 multi-turn optical encoder for feedback, with a resolution of 512 or 2048 lines per revolution. The motor has a frame dimension of 84mm, a smooth shaft, and two SpeedTec Ready connectors, and it does not include a brake system.
Internal Product Review
The AKM44J-ANCNDB00 is a Kollmorgen AKM synchronous servo motor with an EnDAT 2.1 encoder and multi-turn optical feedback. The smooth shaft and 2 SpeedTec Ready connectors support clean mechanical integration and efficient electrical hookup. A standard configuration without brake makes the AKM44J-ANCNDB00 a strong choice for precise servo applications.

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.
