Product Description:
The AKM74Q-GN1NR-02 is a synchronous servo motor produced by Kollmorgen and offered within the AKM Synchronous Servo Motors series. As a compact rotary actuator, it converts electrical drive signals into precise mechanical motion for positioning, indexing, and speed-regulated tasks in industrial automation cells, packaging lines, and electronic assembly stations. Its servo design supports repeatable acceleration and stable speed control on axes that require accurate response during frequent start-stop operation.
This unit is supplied without a brake, so any static holding must be handled by external mechanics or drive torque. A smooth shaft is provided, allowing friction couplings or clamp hubs to seat evenly around the shaft surface without a keyway. The square frame measures 188 mm, which sets the motor's mounting envelope and helps determine machine-side spacing. The housing uses alternative flange variant G, which provides a bolt pattern different from the standard IEC face and can ease installation on legacy equipment. Rotor position is monitored by a resolver, an electromagnetic transducer that outputs sine-cosine signals with good tolerance to vibration and temperature, and those signals are decoded by the drive for commutation and velocity control.
The resolver uses 2 poles, which helps the drive maintain electrical angle accuracy during each revolution. Its feedback is single-turn inductive, so absolute position is available within one mechanical turn and resets after that range, which suits short-stroke applications that do not require multi-turn tracking. The resolver body is Size 10/15/21, indicating a modular range of stator and rotor diameters that fits within the 74-frame stator stack without changing overall motor length. Internal windings use a Q winding layout, matching phase resistance and inductance to compatible drives that can supply high peak current for rapid torque transients. The rotor length index of 4 increases active iron length for higher continuous torque density.
