Product Description:

The AKM52E-CNA2R-70 is a brushless servo motor made by Kollmorgen for the AKM Synchronous Servo Motors series. As a rotary actuator, it converts drive current from a matched servo amplifier into precise mechanical motion for indexing tables, packaging axes, or articulated robot joints. The motor couples directly to the load to deliver repeatable position, speed, and torque control in industrial automation cells where coordinated multi-axis motion is required. Its compact servo design makes it suitable for installations that need accurate response without adding unnecessary mechanical complexity.

It incorporates a 24 V holding brake that locks the shaft when power is removed, helping prevent back-driving on vertical or load-biased axes. Motion feedback is supplied through a resolver, an electromagnetic transducer that tolerates electrical noise and elevated operating temperatures. Inside that feedback device, the rotor uses 2 poles. The feedback system is a single-turn inductive type, so one mechanical revolution corresponds to one electrical cycle. Kollmorgen assigns feedback package Size 10/15/21, which places the feedback hardware within a compatible stator diameter group used across related motor configurations. The rotor length index is 2, placing this model in the mid-torque range of the 52 frame.

The housing measures 108 mm across the mounting pilot, matching medium machine frames used in automated equipment. An alternative flange variant C hole pattern provides added clearance for through-bolts on compact gearboxes or tight mounting faces. A smooth shaft avoids keyway stress concentrations and is suitable for shrink-fit couplings or clamp collars that rely on frictional locking. Electrical behavior is tied to winding code e, which sets the back-EMF constant and rated current range expected by compatible Kollmorgen AKD or S200 drives. This arrangement supports stable integration where shaft alignment, clean feedback signals, and consistent drive matching are important for axis performance.
