Product Description:
The AKM22C-ACBNAA-01 is a synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. As a compact rotary actuator, the motor converts controlled current from a drive into precise torque and speed, allowing machinery axes to position loads, follow motion profiles, or maintain tension in automated cells. It is delivered without a brake, making it suitable for systems that rely on drive holding torque or external locking devices to secure loads at a standstill.
Its electrical and sensing interfaces are organized for rapid installation. Power and signal lines terminate on two SpeedTec-ready connectors, which use a keyed arrangement to support quick and secure mating. Rotor position is measured by a BiSS B encoder that provides 2048 lines per revolution of optical resolution. This resolution allows the drive to execute high-bandwidth current loops and support accurate commutation. The single-turn optical encoder retains absolute position over one revolution without batteries. The encoder electronics use the AD34/AD58 protocol designator, allowing standardized cabling across the AKM family. A compact stator and rotor package fits within a 58 mm square frame, keeping the motor envelope small for multi-axis machines and installations with limited space.
The motor’s mechanical coupling interfaces support installation with compatible IEC gearboxes and mounts. The housing carries an IEC flange with accuracy class N, which keeps runout and pilot tolerances within normalized limits. The shaft transmits torque through a keyway that accepts standard metric hubs and provides positive engagement with the connected coupling. The magnetic stack uses rotor length index 2, balancing continuous torque and rotor inertia for moderate-duty motion cycles. The C winding designation provides phase resistance and inductance suited to typical 230 V-class drives. This winding supports controlled current delivery during acceleration, steady-speed operation, and positioning moves while retaining the compact dimensions associated with this motor frame.
