Product Description:

The AKM42J-EKC22-01 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. The unit translates commanded current into tightly regulated torque and speed, allowing precise indexing, coordinated robotics, and packaging motions inside automated cells. Its electromagnetic core, compact mechanical envelope, and integrated feedback path suit installations that demand repeatable positioning and fast acceleration while conserving panel and machine space. In servo systems, this combination supports accurate starts, stops, and dwell positions without excessive overshoot. It also fits machine layouts where limited clearance around the motor body makes compact drive hardware especially useful.

Reliable axis retention is provided by a 24 V holding brake that locks the shaft whenever bus power is removed. Power and feedback cabling terminate through two SpeedTec Ready connectors, a twist-lock interface that shortens cable attachment time and resists vibration during operation. Rotor position is sampled at 2048 lines per revolution by the integrated Comcoder. Because the sensing element is single-turn optical, the drive receives an absolute angle within one revolution and can restart without homing. Motion data are formatted as EPC 15T, giving a digital signal compatible with AKD drives and many third-party controllers.

The housing follows IEC geometry and uses an 84 mm frame, giving mid-range torque density in a compact footprint. A winding J design sets the copper fill and resistance so the stator works with standard 230 VAC bus systems while keeping thermal rise moderate across the length 2 active stack. Output torque is transmitted through an open keyway shaft that accepts standard keyed couplings, and a front shaft seal helps block coolant or lubricant ingress at the bearing. The IEC-based dimensions support straightforward integration into machines that use standardized mounting interfaces. The sealed shaft area is also useful in enclosed gear stages, conveyor sections, and other installations where moisture or process residue may be present near the drive end.
