Product Description:

The AKM74P-ACCNR-01 is a synchronous servo motor engineered by Kollmorgen as part of the AKM Synchronous Servo Motors series. Designed for closed-loop automation, the unit converts drive-controlled electrical power into rotary motion for tooling, indexing tables, and gantry axes that require repeatable positioning. Its compact electromagnetic package helps reduce machine footprint while preserving the fast response needed in packaging, assembly, and robotics applications. A permanent-magnet rotor and precision stator laminations support steady torque production, while internal thermal paths help move heat away from active components during continuous-duty operation.

Its mechanical construction is supplied without a brake, so holding torque must be provided by the drive or by an external locking device when the axis is stopped. Power, feedback, and ground connections reach the motor through 2 SpeedTec Ready connectors, which provide keyed mating and keep the main interfaces organized in a compact layout. Motion feedback comes from a resolver that generates analog signals with strong noise immunity in demanding industrial environments. The motor uses a 188 mm square frame, and a keyway on the shaft transfers torque to couplings or pulleys. A shaft seal helps limit oil ingress during washdown exposure, and rotor length index 4 adds thermal mass for sustained operation.

Control resolution is set by 2 poles, aligning the electrical cycle with the rotor magnetic structure for accurate commutation. The feedback device provides single-turn inductive position data, giving absolute position information within one revolution and supporting startup without a full multi-turn reading. Mounting uses an IEC flange with accuracy N for consistent pilot fit and bolt alignment on mating machine surfaces. Electrical characteristics match the winding designation P coil set, which is intended for balanced torque density with compatible servo drives.
