Product Description:

The AKM42S-ASSNAD-02 is a synchronous servo motor manufactured by Kollmorgen and included in the AKM Synchronous Servo Motors series. Designed for closed-loop motion platforms, the unit translates commanded current into precise angular displacement and torque, enabling coordinated movement in pick-and-place heads, metering pumps, and small gantry carriages. Its construction focuses on compactness and dynamic response so that integration into multi-axis systems imposes minimal space and inertia penalties, which helps when several axes must fit within a limited machine envelope. This makes it a practical fit for compact equipment that depends on repeatable acceleration and smooth position control.

The motor’s square housing measures 84 mm across the frame, a dimension that fixes its bolt circle and helps machine builders predict payload inertia. Mounting occurs through an IEC flange with accuracy grade N, so alignment tolerances match standard planetary gearboxes without additional centering rings. Cabling departs through a special connector arrangement, which permits alternate pinouts or clocking angles when the default AKM orientation conflicts with enclosure layouts. The unit is supplied without a brake, so no holding mechanism adds axial length or residual drag during high-speed duty cycles. The motor uses a rotor length index 2 core, balancing copper fill against magnetic path length for moderate continuous torque at rated speed.

Performance tailoring is completed by a special winding that changes the voltage-constant relationship, allowing the drive to reach nominal torque when bus voltages differ from the standard baseline and giving the matching amplifier more flexibility in systems with nonstandard supply conditions. Output is carried through a special shaft detail so couplings or pulleys unique to an OEM platform can be mounted without secondary machining. This combination is useful in compact servo axes where standard electrical matching and standard shaft geometry do not suit the surrounding mechanical package in tightly packed machinery.
