Product Description:

The AKM51G-DSCNR-03 is a rotary actuator produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. This brushless unit converts drive current into precise torque for indexing tables, gantry axes, and light machining centers where repeatable positioning is critical. Its electromagnetic design, matched to Kollmorgen drives, allows tight loop control so motion commands issued by the controller are followed with minimal lag or overshoot in industrial automation tasks.

The motor is built with a winding code of G, a configuration that matches the copper fill and electrical resistance to medium-voltage servo amplifiers. A square frame measuring 108 mm on each side keeps the package compact while supplying enough stator volume for continuous torque generation. Inside that frame sits a rotor length index of 1, indicating the shortest rotor stack offered in the 5 × series and reducing inertia for faster acceleration. The unit is supplied without a brake, so holding torque during power-off must be provided by the drive or an external clamp. Power and feedback leave the housing through 2 SpeedTec Ready connectors, allowing keyed, tool-free mating for simpler cable connection.

Position feedback is generated by a resolver, which uses analog sine and cosine signals and maintains strong immunity to electrical noise. The feedback device uses 2 poles, so one electrical cycle represents a full mechanical revolution. Its pickup is rated as single-turn inductive, meaning multi-turn data are not stored, but one-turn accuracy is maintained without batteries. Mechanical mounting follows Flange Variant D, an alternate 108 mm interface that repositions pilot bosses and bolt holes to clear tight frames, while a special nonstandard shaft detail supports proprietary couplings without additional machining.
