Product Description:
The AKM22H-CKS2AD-02 is a brushless synchronous servo motor built by Kollmorgen and supplied in the AKM Synchronous Servo Motors series. Serving as a compact rotary actuator, it converts drive current from a matched servo amplifier into controlled torque and speed for positioning tables, packaging axes, or pick-and-place heads in automated equipment. Integrated feedback channels allow the motion controller to regulate position and velocity, providing repeatable indexing and contouring across a range of production environments. Its compact design supports automated machinery where precise movement and limited installation space are important.
A 24 V holding brake keeps the shaft locked when power is removed, preventing load drift on vertical or suspended axes. The mounting face uses an alternative C flange with a bolt pattern that differs from the standard square arrangement. The motor has a 58 mm frame, which allows it to fit into compact gear stages while retaining adequate stator volume for heat dissipation. Output torque is transmitted through an open keyway on the shaft, providing positive engagement with pulleys, couplings, or gear wheels in servo transmissions. This keyed connection helps prevent rotational slippage between the shaft and the attached transmission component during acceleration and deceleration.
The stator uses an H winding, which provides a voltage constant suited to low-to-medium bus voltages and supports moderate current draw during acceleration. The magnetic stack has a rotor length index of 2, balancing continuous torque capability with a compact axial size. Connection to the drive is handled through a special connector arrangement that separates power and feedback pins for straightforward cable routing and plug-in access. Separating these circuits helps organize the motor connections and reduces the chance of confusing power conductors with feedback wiring during installation. The motor can be paired with a compatible servo amplifier that supplies the required current and processes its feedback signals for closed-loop motion control.
