Product Description:

The AKM31C-ACCNR-00 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. This compact rotary actuator converts drive current into controlled mechanical power for indexing tables, packaging axes, and other automation tasks that demand rapid acceleration and repeatable positioning. When paired with a digital drive and motion controller, it closes the feedback loop required for coordinated multi-axis systems and keeps cycle times short while maintaining commanded trajectories.

The motor is supplied without a brake, so holding position after power is removed requires drive torque or external clamps. Electrical terminations are handled through 2 SpeedTec Ready connectors, a paired plug set that shortens installation time and maintains EMC shielding. Position and velocity are monitored by a Resolver, whose sinusoidal signals tolerate high temperatures and electrical noise, and its housing follows the Size 10/15/21 profile common in Kollmorgen feedback devices. The aluminum stator housing spans a 70 mm frame, matching common IEC size 70 gearboxes and linear stages. Output torque is delivered through a keyway shaft, allowing standard couplings or pulleys to be mounted without additional machining. The unit uses the standard customization level.

With rotor length index 1, moving mass is minimized for short cycles. The rotor employs single-turn inductive feedback, providing an absolute electrical reference inside each revolution without batteries. Commutation uses 2-pole resolution, which supports smooth torque production at low speed. Mechanical centering is provided by an IEC flange with accuracy N, helping reduce runout when the motor is coupled to a gearbox or ball screw. Internally, the copper winding uses winding code C, which matches the current limits and thermal model used by compatible drives.
