Product Description:

The AKM42C-AC5NR-01 synchronous servo motor is produced by Kollmorgen as a member of the AKM Synchronous Servo Motors series. Within an automation cell, this unit converts electrical power from a digital drive into tightly regulated mechanical motion for indexing tables, gantry axes, or coordinated robot joints. Its design follows the AKM platform’s modular approach, letting OEMs choose windings, feedback, and mounting options that match dynamic requirements while keeping the same envelope and cabling style across multiple machine models in a production line.

This version is supplied without a brake, which shortens the package length and lowers reflected inertia, so external holding devices must secure loads when power is removed. The square flange measures 84 mm, giving a mounting face that aligns with common IEC gearheads in medium-torque zones. Position feedback is delivered by a resolver, a transformer-based sensor that tolerates oil mist, vibration, and temperature extremes. With 2 poles of electrical resolution, the magnetic cycles are tracked precisely, enabling smooth field-oriented commutation. Rotor length index 2 increases the active stack height to raise continuous torque within the same frame.

The feedback assembly uses single-turn inductive sensing, so absolute position is known once per mechanical revolution without batteries or multi-turn gears. An IEC flange with accuracy N keeps concentricity errors low, helping the drive maintain efficient torque production at high bandwidths. The output shaft has a keyway, and a factory-installed shaft seal limits dust or coolant ingress along the bearing journal. The motor uses winding C, which matches standard AKD bus voltages. This arrangement suits automated equipment that needs stable feedback, sealed shaft support, and a keyed mechanical connection.
