Product Description:

The AKM22G-CKB22-00 servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. It is a compact permanent-magnet unit intended for closed-loop motion axes in packaging, pick-and-place, and other industrial automation machinery. With its brushless design and integrated feedback, the motor delivers repeatable positioning while keeping installation dimensions small. It supports precise rotary motion on axes that require stable speed control and accurate stopping points during repetitive machine cycles.

Its mechanical envelope uses a 58 mm square frame and Rotor Length Index 2, giving a balanced torque-to-inertia ratio for moderate duty cycles. The stator uses winding designation G to match drives that supply the required current and voltage profile. For power and signal wiring, the housing carries 2 SpeedTec Ready connectors that accept keyed half-turn plugs for quick cable connection. Separate connection points help keep cable routing orderly in compact machine layouts. A 24 V holding brake is installed to lock the shaft when power is removed, supporting vertical loads. The motor reports position through a Kollmorgen Comcoder encoder that delivers 2048 lines/rev of incremental resolution to the controller. The square frame maintains stiffness while allowing the alternative flange to fit the specified bolt circle.

The feedback chain is completed by a single-turn optical disk inside the EPC sensor stack. This architecture omits multi-turn data but minimizes latency during velocity loops. That arrangement supports responsive control during rapid changes in commanded speed. The optical disk works with the EPC 15T ASIC to shape differential channels that resist electrical noise. When space constraints require nonstandard mounting, the motor ships with alternative flange variant C, and the shaft is machined with an open keyway so couplings can be installed without set screws. Because the unit follows the series' standard customization level, no application-specific machining is present.
