Product Description:

The AKM43K-ANSNR-03 servo motor is produced by Kollmorgen within the AKM Synchronous Servo Motors series. The unit serves as a direct-drive actuator for industrial automation tasks that demand accurate velocity regulation and repeatable positioning. By coupling the rotor directly to belts, gearheads, or lead screws, it lets machine controllers generate programmable motion profiles without mechanical backlash. Its size-4 housing offers a midrange torque envelope while preserving the compact footprint expected in multi-axis packaging, printing, and robotic work cells.

The motor has an 84 mm frame dimension, allowing it to fit inside narrow machine frames without obstruction. A lamination stack with rotor length index 3 increases magnetic volume, so continuous torque is higher than that of shorter variants with the same diameter. The coil pattern has winding designation K, with resistance and inductance values suited to Kollmorgen drives rated for this voltage class. Mounting is handled through an IEC flange with accuracy N, which maintains concentricity tolerances for gearheads or load adapters. Output power is transmitted through a smooth shaft, enabling the use of clamp couplers or shrink discs instead of keyed hubs. Cabling exits through a special connector arrangement that repositions the power and feedback plugs to accommodate confined installation layouts and reduce bending stress on the harnesses.

The unit is supplied without a brake, so static load retention must be provided by the drive or external clamps. Position sensing is delivered by a resolver, a passive electromechanical transducer that withstands high temperatures and vibration while returning sine-cosine signals to the controller. The resolver has two poles, providing one electrical cycle per mechanical revolution and supporting single-turn inductive angle detection. This feedback method does not require multi-turn gearing or batteries, which keeps the encoder section compact and reduces maintenance requirements.
