AKM44J-ANRNMB-02

The AKM44J-ANRNMB-02 from Kollmorgen represents a high-performance member of the AKM Synchronous Servo Motors series designed for demanding industrial automation applications. This synchronous servo motor delivers a continuous stall torque of 6.00 Nm and operates up to a maximum speed of 6000 rpm, ensuring dynamic response for precision motion control. With a compact frame dimension of 84 mm and a motor weight of 5.3 kg, the unit balances high torque density and minimal footprint. The motor’s two-pole design and rotor length index of 4 further contribute to its agile performance and rapid acceleration profiles. This unit supports high-voltage operation on both 480 VAC input voltage and 400 VAC systems, offering flexibility across industrial power infrastructures.

Featuring an advanced winding and rotor assembly, this servo motor exhibits a winding resistance of 0.88 Ω and an inductance of 6.16 mH, optimized for efficient current-to-torque conversion. The device achieves a voltage constant of 44.2 mV/min⁻¹ and generates a torque constant of 0.69 Nm/A, delivering precise torque per ampere in dynamic applications. The rotor inertia of 0.000273 kg·m² ensures low reflected inertia for improved positioning accuracy, while the static friction torque of 0.04 Nm minimizes stiction at start-up. Thermal performance is managed through a thermal time constant of 22–24 minutes, enabling reliable overload handling. Peak current capacity reaches 35.2 A, producing a maximum torque of 20.4 Nm for short-duration high-load events.

Operational reliability is guaranteed by robust protection and feedback systems. The motor’s standard IP54 rating (upgradable to IP65 and IP67 with shaft seal suffix) defends against dust and water ingress, while its insulation class F construction ensures sustained performance at elevated temperatures. The motor incorporates a smooth shaft design and a precision shaft seal (suffix 02) to maintain environmental integrity. The integrated resolver feedback system provides closed-loop accuracy without external encoders. Optional brake configurations (Brake System: Without brake or with brake) feature a brake torque of 6 Nm and additional Brake Inertia of 0.0000068 kg·m², ensuring safe holding capability and controlled deceleration.

Seamless integration into automation architectures is facilitated by a versatile Connector Arrangement: 1 M23-6 Power, 1 M12 Feedback, supporting industry-standard feedback protocols including SFD3, HIPERFACE, DSL, EnDat 2.2, BiSS, and resolver interfaces. The motor’s Flange Configuration: IEC with accuracy N and Product Family: AKM Synchronous Servo Motor designation simplify mechanical mounting and controller compatibility. Engineers can leverage the unit’s compact Frame Dimension and consistent interface for rapid deployment in robotics, packaging machinery, and CNC systems. With its combination of high torque density, configurable protection levels, and broad feedback support, the AKM44J-ANRNMB-02 is an ideal solution for advanced motion control challenges.
