Product Description:
The AKM22H-CKSNAD-02 is a brushless servo motor in the AKM Synchronous Servo Motors series and is produced by Kollmorgen for precision motion tasks in industrial automation. Serving as the electromechanical actuator between a servo amplifier and a load, the unit delivers rapid torque response and repeatable positioning. Its compact build facilitates integration into pick-and-place heads, indexing tables, and other small-frame axes where dynamic performance and a limited installation envelope are equally important.
The frame measures 58 mm across the mounting pilot, providing a balanced ratio between inertia and continuous torque for midsize tooling. An alternative C flange shifts the bolt circle relative to the standard AKM pattern, simplifying installation on legacy gearboxes. Axial wiring exits through a special connector arrangement that accommodates shielded power and feedback leads while keeping the total motor length unchanged. The shaft has an open keyway, allowing positive coupling to pulleys or rigid hubs without relying on friction alone. Because the unit is supplied without a brake, external holding measures are required when vertical loads or emergency stops require static torque retention.
The rotor length index of 2 indicates the active stack height and supports the continuous torque capacity available from this frame size. The stator uses a high-temperature winding system with winding designation H, permitting higher current before the motor reaches its thermal limits. Rare-earth magnets provide a strong magnetic field for responsive torque production, while digital feedback supplies the servo amplifier with motion data for synchronous operation across the speed range. The electromagnetic configuration supports accurate current regulation during acceleration, steady-speed operation, and controlled deceleration. These operating characteristics allow the motor to maintain repeatable motion without requiring forced cooling in applications that remain within its rated load and temperature limits.
