AKM22C-ENB2R-00 by Kollmorgen

The AKM22C-ENB2R-00 is an AC synchronous servo motor manufactured by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. This compact unit functions as a rotary actuator that delivers programmable motion for pick-and-place heads, light gantries, and packaging axes, pairing with a matched drive to regulate velocity and position through real-time feedback. It combines smooth shaft mechanics with an internal resolver so closed-loop control can be maintained during rapid load changes, and its compact format suits installations where mounting space is limited.

The motor body measures 58 mm across the frame, and six rotor poles interact with winding designation C to create the magnetic field used for torque production. A rear-mounted 24 V brake supplies 1.42 Nm of holding torque, allowing vertical axes to remain locked when power is removed. Two SpeedTec-ready connectors simplify cabling by separating power and feedback lines. Dynamic profiles are supported by a peak current of 5.6 A, which can generate up to 2.73 Nm of peak torque for acceleration, while the rotor inertia of 0.16 kg cm² keeps response quick. Position information comes from a resolver with 2-pole electrical resolution; its single-turn inductive design in size 10/15/21 provides feedback without batteries.

During steady operation, the motor draws 1.39 A of standstill current to deliver a continuous torque of 0.84 Nm, which suits small indexing tables and feed rollers. The electromagnetic conversion factor is 0.61 Nm/A, enabling the drive to predict output torque directly from commanded current. Coil design includes a phase-to-phase inductance of 35.5 mH and a resistance of 20.0 ? at 25 °C, and these values influence servo loop bandwidth and thermal rise. These values also affect current response during dynamic operation. The build follows the standard customization level, and rotor length index 2 identifies the mechanical stack used in this model.
