Product Description:

The AKM21E-ANCN1-00 is a compact servo motor manufactured by Kollmorgen as part of the AKM Synchronous Servo Motors series. Designed to convert electrical power into precisely controlled rotary motion, the unit integrates easily into packaging, electronics assembly, and material-handling axes that rely on tight position loops. Its frame size, electrical design, and feedback arrangement allow motion controllers to command incremental moves, speed changes, and torque response with minimal following error. In compact automation cells, that combination supports accurate starts, stops, and direction changes during repetitive cycles. The motor can serve as a precise rotary actuator in equipment that requires repeatable positioning in a limited installation space.

The frame dimension of 58 mm across the IEC flange fits the motor to gear stages and slide tables. Power and feedback conductors exit through 2 SpeedTec Ready connectors, allowing tool-free mating while preserving connector sealing. Rotor position is reported by a Comcoder device that delivers 1024 lines/rev, and the drive multiplies these lines for velocity and position loops. This transducer is a single-turn optical device, so absolute angle is valid within one revolution and the system must index at startup. The motor is supplied without a brake, so a mechanical clamp or drive torque must hold the load during power loss.

The flange follows IEC with accuracy N, so concentricity and perpendicularity match the normal tolerance class used on modular gearheads. A smooth shaft permits coupling with clamp hubs or timing pulleys without keyways, which helps reduce backlash in servo assemblies. Internally, winding code e indicates the voltage constant and rated current used with drives that operate in low-to-medium bus voltage ranges. The feedback identification string EPC 15T supports plug-and-play recognition inside Kollmorgen motion controllers, and rotor length index 1 helps keep inertia low for high-acceleration profiles.
