Product Description:

The AKM21E-ENBN2-00 is a brushless servo motor manufactured by Kollmorgen in the AKM Synchronous Servo Motors series. It is intended for precise rotary motion in packaging equipment, pick-and-place units, and compact robotic axes where accurate speed and position control are required. When paired with a compatible drive, the motor converts commanded current into repeatable shaft motion for automated machinery. Its compact format suits installations that need responsive movement, predictable feedback behavior, and reliable operation in tightly spaced mechanical assemblies.

This model uses a frame dimension of 58 mm, which helps it fit compact mounting spaces while providing room for the active magnetic parts needed for its torque range. Power and feedback connections are made through two SpeedTec Ready connectors, and the keyed bayonet style supports fast, secure cable attachment without loose coupling during machine vibration. Position data is supplied at 2048 lines/rev, giving the drive fine incremental information for stable servo control, and the sensing element also includes an index channel for reference tracking. Mechanical output is transmitted through a smooth shaft, which works well with clamp-style hubs and avoids the stress concentration associated with a keyway.

The winding designation is e, indicating the electrical winding version used for this motor. Feedback is provided by single-turn optical feedback, which gives precise rotor position information without using a multi-turn gear train and suits high-cycle motion. The feedback format is EPC 15T, allowing recognition by supported controllers, while rotor length index 1 identifies the shortest active stack in this frame size. The customization level is standard rather than modified, and the motor is supplied without a brake, so holding torque at standstill must be provided by the drive or by an external mechanical restraint.
