Product Description:

The AKM44E-SSCNR-04 is a brushless servo motor assembled by Kollmorgen for the AKM Synchronous Servo Motors series. In automated machinery, it supplies closed-loop torque and position control, allowing motion controllers to drive axes precisely without mechanical backlash. The unit fits medium-frame applications where compact dimensions and resolver feedback are preferred, making it appropriate for packaging, electronic assembly, and pick-and-place stages. It converts drive current into synchronous rotation that follows commanded motion profiles.

The motor’s power and signal cabling is handled through two SpeedTec-ready connectors, which use a twist-lock arrangement that reduces installation time and maintains the enclosure seal once engaged. Rotor position and velocity are reported by a resolver, providing analog sine-cosine feedback that resists electrical noise. This transducer uses a single-turn inductive architecture, so the controller can read the absolute angle within one mechanical revolution. The motor has a frame dimension of 84 mm, allowing direct attachment to gearheads and mounts sized for IEC 72-compatible motors. Dynamic capability is increased by rotor length index 4, which adds active iron length for higher continuous torque without widening the frame.

The shaft is supplied without a brake, so any static holding requirement must be met by the drive or an external clamp. Feedback wiring follows the industry coding for Size 10/15/21, supporting integration with compatible feedback connections in mixed-vendor installations. The mounting holes follow a special flange outline, enabling installation on custom plates where standard square flanges would interfere with adjacent components. The internal winding designation E corresponds to the phase resistance and inductance parameters used by compatible Kollmorgen drives, allowing the axis to reach commanded accelerations while remaining within the thermal limits of the frame and rotor geometry.
