Product Description:

The AKM11E-BNMN2-00 is a compact servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. It is intended for closed-loop motion axes in packaging, semiconductor, and general automation equipment, where accurate torque and speed response are needed during frequent starts, stops, and position changes. The motor converts commanded drive current into controlled rotary motion for small stages, feed mechanisms, and other space-limited assemblies. Its compact housing also helps it fit installations where the motor must be mounted close to guides, couplings, or process tooling. Its electrical design is intended to work with Kollmorgen drive families for coordinated servo control and consistent feedback handling.

Feedback performance is provided by the integrated Comcoder, an electro-optical sensor that returns 2048 lines/rev of incremental position data to the drive. The encoder is a single-turn optical device that supports precise position feedback in short-stroke mechanisms and other axes that require repeatable motion within a limited travel range. Mechanical attachment follows the NEMA flange pattern, so the housing bolts directly to standardized face plates without special adapter hardware. The square frame dimension of 40 mm keeps the overall footprint small, and the smooth shaft favors clamp couplings that reduce backlash at the connection point.

The rotor length index indicates the shortest magnetic stack in this frame size, and the Standard customization level uses the regular option set for this model. A winding designation of e matches the stator to medium bus voltages, supporting a balance between torque output and thermal behavior during continuous duty. Because the motor ships without a brake, holding torque must be supplied by the drive or by an external clamp when power is removed. This configuration also avoids the extra inertia that a brake assembly would add. That arrangement is commonly acceptable on axes that already use a mechanical lock or do not need a parking brake at standstill.
