Product Description:

The AKM65K-ACCNR-B0 is a synchronous servo motor manufactured by Kollmorgen and supplied within the AKM Synchronous Servo Motors series. The model belongs to the AKM family of brushless permanent-magnet actuators that provide closed-loop torque and speed control for industrial machinery. By integrating a compact stator, a rare-earth rotor, and a precision feedback device, it drives linear slides, rotary tables, and gantry axes with repeatable accuracy and high dynamic response in packaging lines, semiconductor tools, and general automation equipment. Its electromechanical interface conforms to IEC mounting conventions, allowing installation in existing layouts without adapter redesign.

Electrical terminations are handled through two SpeedTec Ready connectors, allowing keyed plug-in power and feedback cables that lock with a quarter turn and do not require hand tools. Motion feedback is provided by a resolver, a transformer-based sensor that tolerates heat and electrical noise. This resolver is configured for single-turn, inductive operation, so the absolute position repeats every revolution and no multi-turn memory is needed. The housing outside diameter measures 138 mm, which supports direct attachment to a matching gearbox or machine flange. Because the unit is supplied without a brake, any holding function must be provided by the drive or an external clamp.

Commutation accuracy is maintained by a resolver that incorporates 2 poles, aligning electrical phase with mechanical rotation for consistent torque production. Installation precision benefits from a flange machined to IEC accuracy N, which matches standard reducers and helps minimize shim requirements. Torque is transmitted through a shaft with a keyway, ensuring positive engagement with couplings and helping prevent slip under peak demand. The electromagnetic section corresponds to index 5 in the rotor length scale, and its K winding variant balances voltage use and continuous current so the motor can pair with medium-voltage drives while still delivering high peak torque during rapid cycles.
