Product Description:
The AKM41H-ACSN2-02 is a brushless servo motor produced by Kollmorgen and supplied under the AKM Synchronous Servo Motors series. This model belongs to the AKM family frame 4 platform and is built to deliver controlled torque and speed for indexing tables, packaging axes, and other precision motion stages used in industrial automation. The motor pairs with matched Kollmorgen drives to form a closed-loop system that maintains position accuracy under varying process loads.
The mechanical stack follows rotor length index 1 and the H winding designation, resulting in thermal and electrical parameters suited to moderate continuous duty cycles. The unit is supplied without a brake, so holding torque during power loss must be provided by the drive or an external mechanism. Position data originates from an optical feedback disk that offers 2048 lines per revolution of incremental resolution. This signal is generated by the integrated Comcoder, a sensor that combines commutation and incremental channels in a single module. This configuration allows the drive to read the rotor position during startup while supporting high-bandwidth velocity loops. The square housing measures 84 mm across the frame, allowing the motor to fit IEC 72 standard gearboxes and compatible machine plates without adapters.
A special connector arrangement places the power and feedback plugs on the stator perimeter to accommodate tight installation layouts. Absolute indexing within one revolution is provided by a single-turn optical track, and the identification code EPC 15T allows the drive to load the correct scaling factors automatically. The motor uses an IEC flange with accuracy N, so concentricity and perpendicularity remain within standard limits when the motor is clamped to precision actuators. Output torque is transmitted through a shaft machined with a keyway, simplifying connections to pulleys or rigid hubs while preventing slip under peak acceleration. The flange arrangement supports accurate alignment between the motor shaft and connected equipment. The keyed shaft provides positive mechanical engagement where a clamping-only connection is not suitable.
