AKM53K-ACCNEF-00 by Kollmorgen

The Kollmorgen AKM53K-ACCNEF-00 synchronous servo motor from the AKM Synchronous Servo Motors series delivers precision motion control in industrial automation environments. This compact design provides a continuous stall torque of 11.6 n-m and a peak stall torque of 30.3 n-m, driven by a permanently magnetized rotor that ensures consistent performance. Rated power output reaches 3228 watts at 480VAC, with a corresponding maximum speed of 5550 rpm under the same conditions. The motor's robust frame and optimized electromagnetic design accommodate demanding acceleration and deceleration profiles with minimal cogging and harmonic distortion. Integrated thermal management achieves reliable operation from -20°C to 40°C, making the AKM53K-ACCNEF-00 suitable for a wide range of factory and process automation tasks.

Detailed specifications underscore the AKM53K-ACCNEF-00's engineering precision: it features a torque constant of 1.23 n-m/Arms and a back EMF constant of 79.8 Vrms/krpm for efficient energy conversion. Electrical characteristics include a peak stall current of 28.2 Arms and a continuous stall current of 9.4 Arms, with derated performance of 7.48 Arms and 9.28 n-m continuous torque at 60°C rise. The motor's Rotor Length Index of 3 aligns with the IEC flange configuration with accuracy N and a 108 mm frame dimension, facilitating direct replacement or new installation in standard mounts. Two SpeedTec Ready connectors provide a streamlined connector arrangement with and without optional brake configurations, while the brake system without brake variant maintains a lightweight profile.

Operational performance is optimized by a thermal time constant of 28 minutes, allowing predictable heat dissipation under sustained load. Static friction is maintained at 0.058 n-m (less shaft seal), ensuring low drag torque for precise low-speed positioning. The unit operates across input voltages of 240VAC, 400VAC, and 480VAC, achieving 2780 rpm at 240VAC and 4860 rpm at 400VAC alongside its top speed. Inertia and vibration characteristics support high dynamic responsiveness, while durable materials and compliance with CE and UL approvals guarantee reliability in harsh industrial conditions.

Seamless integration with Kollmorgen servo drives and controllers is achieved through the native AKM Synchronous Servo Motor product family interface and SpeedTec Ready connectors. The AKM53K-ACCNEF-00 supports multiple feedback options and is compatible with Brake System expansions and shaft arrangement variants for customized motion solutions. Its modular architecture and standardized frame dimensions simplify system design, maintenance, and scalability. Ideal for CNC machinery, robotic articulations, packaging lines, and high-precision indexing tables, this motor excels where accuracy, repeatability, and uptime are paramount.
