Product Description:

The AKM42G-EKC22-00 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. Within an automation cell, it converts commanded current from the drive into precise rotary motion for positioning axes, indexing tables, or coordinated gantry elements. Its compact frame size allows direct mounting on machinery, and the motor’s electromagnetic design supports rapid torque changes needed in closed-loop motion systems that require high throughput and repeatable accuracy.

This model incorporates a 24 V holding brake that clamps the rotor when power is removed, helping prevent unintended drift on vertical or load-bearing axes. Position data is supplied by a Comcoder device that combines commutation and incremental tracks so the drive immediately knows the electrical angle and can fine-tune velocity. The optical disc yields a native resolution of 2048 lines/rev, giving the controller detailed feedback for smooth speed regulation and tight position control. Because the encoder is a single-turn optical unit, absolute position is retained over one mechanical revolution without additional multiturn gearing.

The motor housing follows an IEC 60349 footprint and has an 84 mm square frame that fits compactly into multifunctional assemblies. Power and feedback are routed through two SpeedTec Ready connectors, allowing quick plug-in wiring and positive bayonet locking in high-vibration areas. For coupling to gearboxes or pulleys, the shaft is machined with an open keyway, which provides a positive torque transfer path without custom hubs. The electromagnetic length corresponds to Rotor Length Index 2, and the stator uses a G winding that matches this frame to drives delivering voltage and current suited to medium-speed, moderate-inertia loads in packaging lines, pick-and-place heads, and electronic assembly stations.
