AKM41S-ANS22-03 by Kollmorgen

The Kollmorgen AKM41S-ANS22-03 servo motor is a high-performance unit in the AKM Synchronous Servo Motors series, engineered for demanding industrial automation tasks. It delivers a continuous stall torque of 2.1 N-m and a peak stall torque of 7.26 N-m within a compact 70 mm diameter housing. The design features an IP54 protection rating for resistance to dust and water spray, making it suitable for semi-protected or light industrial environments. With a rotor inertia of 0.000059 kg-m², the AKM41S-ANS22-03 ensures rapid acceleration and precise dynamic response under varying load conditions. Its robust construction and compact form factor enable seamless integration into space-constrained systems.

Key technical specifications underscore the motor’s versatility and performance. The device incorporates a Brake System: 24V holding brake for secure stops in vertical or safety-critical axes. It uses an EPC 15T feedback type to deliver high-resolution position feedback, paired with a Special Connector Arrangement for simplified cabling. The Frame Dimension is 84 mm, with a Shaft Diameter of 14 mm on a Smooth Shaft detail, and a Rotor Length Index of 1. A Torque Constant of 0.38 N-m/Arms and a Continuous Stall Current of 5.5 Arms enable efficient torque delivery, while the Peak Stall Current of 22 Arms supports high startup loads. The motor’s Motor Length is 140.8 mm, with a Special Winding designation and an IEC flange configuration with accuracy N for precise mounting alignment.

Operational performance benefits from a Thermal Time Constant of 17 minutes, allowing sustained operation without thermal runaway during repeated duty cycles. The low rotor inertia of 0.000059 kg-m² ensures minimal overshoot and fast settling times in positioning tasks. Continuous torque capability of 2.1 N-m and a peak torque of 7.26 N-m accommodate rapid acceleration demands while maintaining accuracy. The combination of 0.38 N-m/Arms torque constant and robust feedback minimizes electrical consumption, optimizing mechanical efficiency across a wide speed range. Its IP54 protection and rugged build quality deliver reliable operation in dusty or slightly wetted environments, reducing maintenance intervals.

System integration is streamlined through compatibility with a broad range of Kollmorgen drives and controllers, facilitating advanced motion control features such as auto-tuning and vibration suppression. The motor’s compact 70 mm diameter and 140.8 mm length make it ideal for retrofit projects, robotics, packaging machinery, and compact conveyor systems where space is at a premium. Engineers benefit from standardized IEC flange configuration and Special Connector Arrangement to reduce design complexity and shorten time to market. The AKM41S-ANS22-03 excels in industrial automation, precision assembly, and laboratory instrumentation where reliability, accuracy, and dynamic performance are paramount.
