Product Description:

The AKM22C-ANBNGB-00 is a permanent-magnet synchronous servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. Installed on an automation axis, it converts drive current into controlled torque and speed for packaging, electronics assembly, and light robotics. The model belongs to the 22C rotor group, providing medium inertia for responsive yet stable motion. It integrates directly with SERVOSTAR drives and other IEC-compatible drive controllers used in industrial machinery.

Its housing is built on a 58 mm square frame, and the front face uses an IEC flange with accuracy class N so reducers or actuators can be mounted without alignment blocks. Output torque is carried through a smooth shaft, allowing collet or clamp couplings to seat without key backlash. Power and feedback conductors leave the stator through two SPEEDTEC-ready connectors. Their quarter-turn bayonet sleeves simplify wiring and lock securely against vibration. The magnetic stack has a rotor length index of 2, providing higher continuous torque than index 1 units while keeping the overall length moderate. Electrical resistance and inductance follow winding designation C, matching the rated current range of mid-power AKD and SERVOSTAR amplifiers.

Position information is generated at 128 lines per revolution by a HIPERFACE encoder, and drive-side interpolation supports fine velocity control from this feedback. The sensing assembly is a multi-turn optical encoder based on the SKM36 platform, so it retains the absolute shaft angle across 4,096 turns after power loss. Because the motor is supplied without a brake, static holding torque must be provided by the drive’s torque mode or by an external mechanical device when the axis is idle. This arrangement allows the motor to provide position feedback immediately after power is restored without requiring the axis to repeat a homing cycle.
