AKM42G-EKCNR-00
by Kollmorgen
The AKM42G-EKCNR-00 servo motor, manufactured by Kollmorgen as part of the AKM Synchronous Servo Motors series, delivers a compact, high-performance solution for precision motion control. With a Frame Size of AKM4 and an 84 mm Frame Dimension, this motor fits seamlessly into modular automation systems. The unit supports a Max BUS (VDC) of 640, offering ample voltage headroom for demanding applications, and produces a peak torque (Max Tp) of 20.4 Nm. Its continuous mechanical output is rated at 1.73 kW (Max Rated Power at Max BUS), while sustaining speeds up to 6000 rpm (Max Rated N). The motor’s front end is built without a brake (Brake System: Without brake) and utilizes an Open Keyway Shaft Detail for straightforward mechanical coupling.
Performance characteristics of the AKM42G-EKCNR-00 center on precise feedback and robust electromagnetic design. A Resolver Feedback System provides rotational position data with a Feedback Resolution of 2 poles over a Single turn, inductive Feedback Turns arrangement, ensuring reliable operation under variable loading. The motor windings bear the designation G (Winding Designation), optimized for torque density and thermal management. With a Rotor Length Index of 2 and a Stack Length of 2, the design balances inertia and dynamic response to support rapid acceleration and deceleration cycles. Rated stall torque (Max Stall Tc) reaches 6.0 Nm, allowing the servo to maintain stability under transient loads. Two SpeedTec Ready connectors (Connector Arrangement) simplify electrical integration and reduce installation time.
Engineered for durability and seamless system integration, the AKM42G-EKCNR-00 features a robust enclosure and modular interface that support high-duty-cycle operation. The standard customization level (Customization Level: Standard) streamlines selection and delivery, while the inclusion of a single-turn inductive resolver enhances long-term reliability in harsh environments. This motor excels in applications such as robotic articulation, pick-and-place machinery, and CNC tooling, where precise torque control, high speed, and compact form factor are essential. Its open-keyway shaft, flexible mounting options, and compatibility with Kollmorgen AKD servo drives make it ideal for system upgrades and new machine designs requiring consistent, repeatable performance.
