Product Description:

The AKM22C-ESDNC-02 servo motor is built by Kollmorgen for the AKM Synchronous Servo Motors series and is used on closed-loop axes that require repeatable torque and rapid velocity transitions. It converts drive current into mechanical rotation for feeders, small conveyors, and compact pick-and-place heads, helping machine builders maintain tight position tolerances in space-limited equipment. Its compact frame simplifies direct flange mounting and keeps thermal paths short, supporting continuous operation in typical production environments. The permanent-magnet design provides responsive acceleration when the motor is paired with a compatible servo drive. Closed-loop control also allows the connected drive to correct changes in speed or position as the mechanical load varies.

The aluminum housing measures 58 mm across the flange, providing a standardized footprint that aligns with planetary gearboxes in the same size class. The stator coils use winding code C, indicating resistance and inductance values selected for moderate bus voltages and quick current rise. The unit is supplied without a brake, so holding force must come from external mechanics or the servo drive’s torque mode when the axis is stationary. Rotor position is captured through the SFD feedback interface, which combines inductive sensing with electronic memory for parameter storage. This interface transmits incremental and commutation data over four lines, reducing cable bulk while preserving noise immunity in electrically harsh cabinets. The streamlined feedback connection helps reduce the number of individual conductors that must be routed between the motor and drive.

The feedback housing uses the Size 10/15/21 outline, providing a consistent mechanical interface for the encoder assembly. Its sensing element provides single-turn inductive feedback without relying on optical disks or geared mechanisms that may be affected by contamination or wear. Power conductors, commutation channels, and encoder signals are routed through one i-tec Hybrid or SpeedTec-ready Hybrid connector, reducing the number of separate cable connections and minimizing wiring errors. Torque is delivered through a special shaft configuration that mates with custom couplings, while the rotor uses a length index of 2. The selected rotor stack balances inertia against peak torque for responsive and stable motion profiles. This balance supports controlled acceleration and deceleration in compact machinery with frequently changing movement commands.
