Product Description:

The AKM21C-ANBN1-00 is a brushless servo motor manufactured by Kollmorgen and supplied as part of the AKM Synchronous Servo Motors series. Designed for closed-loop motion axes in pick-and-place gantries, indexing tables, and light assembly tooling, the unit provides precise torque output when paired with a digital drive. Its compact housing and permanent-magnet rotor allow tight mounting envelopes while delivering repeatable position control for demanding industrial automation tasks. This makes it suitable for compact machinery that requires responsive motion and consistent tracking through repeated cycles.

A frame diameter of 58 mm keeps the motor narrow enough for multi-axis clusters. Winding designation C sets the voltage-current profile that the matching drive must supply. Power and feedback exit through two SpeedTec Ready connectors, allowing keyed push-and-turn mating and reliable EMC grounding. The separated connections also help keep cabling organized in dense machine layouts. Rotor position is monitored at a native resolution of 1024 lines per revolution, produced by the integrated Comcoder sensor. This incremental feedback lets the controller interpolate fine position data for smooth velocity loops, stable low-speed control, and accurate short moves under high dynamic loads.

The feedback track uses a single-turn optical code disk and carries model-specific index information through the EPC 15T signal format. This arrangement helps the control system recover reference information after power cycles. An IEC flange with accuracy N mates directly to standardized gearheads, and the smooth shaft eases coupling alignment while minimizing backlash. This layout supports direct coupling to common transmission components. The rotor length index of 1 keeps inertia low for quick acceleration. The motor is supplied without a brake, so static holding torque must come from the drive or external mechanics.
