Product Description:
The AKM51G-HNCN2-00 servo motor is produced by Kollmorgen within the AKM Synchronous Servo Motors series. As an AC synchronous unit, it delivers precise position and velocity control for packaging stations, pick-and-place axes, and other industrial automation tasks that rely on closed-loop drives. The motor has a Standard customization level, allowing it to be integrated without special machining or wiring changes.
The motor body has a frame dimension of 108 mm, and its housing uses an alternative H flange as the mounting face. Power and feedback are routed through two SpeedTec-ready connectors, which support keyed quarter-turn locking and simplify cable installation. Position signals are generated by a Comcoder that provides 2048 lines per revolution of incremental resolution, giving the drive the granularity needed for smooth motion at low speeds. The keyed connectors help prevent incorrect cable alignment while providing secure power and feedback connections. The mounting arrangement supports direct attachment to compatible machine frames, gearboxes, and coupling assemblies without requiring an intermediate mounting plate.
The motor uses a smooth shaft that mates with clamp or compression couplings and eliminates the stress concentration associated with a keyway. Inside the stator, the motor has a G winding designation, which corresponds to the electrical characteristics required by a compatible drive amplifier. The feedback assembly uses a single-turn optical arrangement and has an EPC 15T feedback type, allowing the drive to monitor rotor position over one mechanical revolution while supporting high-speed signal scanning. Because the motor is supplied without a brake, an external holding mechanism is required if the load must remain stationary after drive power is removed. A rotor length index of 1 shortens the magnetic stack to reduce rotor inertia, which supports responsive acceleration and deceleration during repetitive positioning cycles.
