Product Description:

The AKM22E-BNM22-01 belongs to the AKM Synchronous Servo Motors series manufactured by Kollmorgen. It is a compact rotary actuator built for closed-loop motion tasks in industrial automation, where precise torque, speed, and position control are required. The motor is used with Kollmorgen drives and uses the series' modular winding and feedback options to suit different application voltages, feedback requirements, and inertial loads. Its compact format is suited to axes where installation space is limited but repeatable motion is still required.

This model includes a 24 V holding brake that locks the rotor when power is removed, preventing drift on vertical or indexing axes. Position data are delivered through a 2048 lines/rev incremental encoder that offers fine commutation and velocity feedback. The sensing hardware is a Comcoder, which combines optical tracks and commutation channels in one housing to minimize wiring. A NEMA flange pattern supports mounting in equipment that uses this geometry, while the 58 mm frame dimension keeps the package small for space-limited machines. The winding designation e and rotor length index 2 indicate the copper fill and magnetic stack depth, which shape the continuous torque curve and compatible drive current range.

A shaft seal blocks coolant or dust from traveling along the output shaft into the stator cavity, complementing the smooth-body housing. Inside the encoder, a single-turn optical track records absolute position within one revolution, and the EPC 15T code wheel identifies the photolithographic pattern used for that measurement. The motor employs a smooth shaft, which helps reduce fretting at the coupling interface and supports sliding-fit assemblies. That arrangement keeps the output interface simple for direct coupling to light gearheads or pulleys.
