Product Description:

The AKM51G-ANCNR-00 is a synchronous servo motor produced by Kollmorgen in the AKM Synchronous Servo Motors series. Designed for closed-loop motion, it converts electrical power into controlled rotation for pick-and-place systems, feeders, and indexing modules. Its mechanical outline supports straightforward integration with gear reducers and machine frames, which helps maintain alignment in compact automation layouts. In automated equipment, that controlled motion helps transfer parts, meter product flow, and index tooling with consistent repeatability from one cycle to the next. This motor is suited for applications that need accurate speed and position control during frequent operating cycles.

This version is supplied without a brake, so holding torque must be provided by the drive or by an external locking device when power is removed. Power and signal wiring use 2 SpeedTec Ready connectors, a keyed arrangement that supports quick connection and secure cable routing. Position feedback is generated by a Resolver with 2 poles, giving the motor a rugged inductive sensing method suited for vibration-prone machinery. The feedback system uses single-turn inductive feedback, and the sensor head matches size 10/15/21 so standard cable sets can be used between the motor and the controller. Because resolver sensing is analog and inductive, it remains effective in environments with electrical noise or mechanical shock.

The motor uses the Standard configuration, so it is supplied without special shaft or winding modifications. The flange is machined to IEC with accuracy N, which helps maintain concentricity during mounting, and the square frame measures 108 mm across. The output end features a smooth shaft that mates with compression couplings or clamps without keyways. Internal construction uses winding designation G, and the rotor length index 1 matches the thermal capacity of this frame size for moderate bus-voltage applications. The frame code 5 housing gives a compact mounting envelope for machinery that needs servo performance without a large motor footprint.
