AKM42E-EKM22-00 by Kollmorgen

The Kollmorgen AKM42E-EKM22-00 is a precision servo motor controller module in the AKM Synchronous Servo Motors series, designed by Kollmorgen for high-performance motion control. This unit is electrically isolated and supports an input voltage range of 100-240 VAC, ensuring broad compatibility with standard industrial power systems. Featuring 2 CAN interfaces, it enables robust real-time communication over CAN networks. As a controller module, its primary function is to drive and regulate a 3-phase brushless motor winding integrated within the stator, providing reliable torque and positional accuracy in automated machinery.

Detailed technical specifications include a compact 84mm frame dimension and a rotor length index of 2, balancing power density and inertia for rapid dynamic response. The unit incorporates a 24V holding brake for secure stops and controlled deceleration during positioning tasks. Feedback is handled by an EPC 15T encoder with 2048 lines/rev single-turn optical resolution, offering precise position feedback for closed-loop control. The open keyway shaft detail facilitates integration with standard couplings and power transmission components. This model’s electrically isolated design and network capability make it uniquely resistant to ground-loop interference while enabling seamless integration into modern industrial automation systems.

Additional features emphasize installation flexibility and operational efficiency. The module supports screw-in mounting (TB712 terminal block ordered separately) for secure attachment within motor assemblies. Its standard customization level and compact form factor simplify system design and maintenance. With power consumption of just 14.5 W, the controller minimizes heat generation and energy costs during idle and low-load conditions. The integration of dual CAN interfaces ensures high reliability in multi-axis configurations and complex control architectures. In industrial applications, the AKM42E-EKM22-00 delivers exceptional durability, precise motor control, and streamlined connectivity, resulting in enhanced throughput, reduced downtime, and optimized energy efficiency.
