Product Description:

The AKM22C-ENB2R-00 is a compact brushless servo motor manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. Supplied with a smooth shaft and two SpeedTec-ready power and feedback connectors, it is intended for positioning or velocity control tasks in industrial automation where rapid response and precise repeatability are required. A single-turn inductive resolver supplies rotor position data through a two-pole design, while the six-pole electromagnetic configuration delivers consistent torque across the motor’s operating range.

The motor frame measures 58 mm, allowing installation in tight mechanical spaces. During acceleration or brief load spikes, the motor can deliver a peak torque of 2.73 Nm, supported by a peak phase current of 5.6 A. The electromagnetic circuit converts current to torque at a rate of 0.61 Nm/A. The phase-to-phase winding inductance of 35.5 mH moderates current rise time and helps filter high-frequency inverter pulses. Winding designation C, combined with rotor length index 2, establishes the copper fill and magnetic stack depth associated with these electrical characteristics. Six rotor poles interact with the stator field, and the resolver matches the size 10/15/21 mechanical outline so it fits directly behind the stack without increasing the motor’s overall length.

The motor develops a continuous standstill torque of 0.84 Nm at a standstill current of 1.39 A. Its rotor inertia of 0.16 kgcm² supports responsive acceleration while maintaining smooth mechanical movement. A 24 V holding brake supplies a static torque of 1.42 Nm to secure vertical or biased loads when motor power is removed. The phase winding resistance is 20.0 Ω at 25 °C, an electrical value that must be considered when matching the motor to a compatible servo drive. The smooth shaft supports clamping couplings, while the separate power and feedback connections simplify cable routing in compact machine assemblies.
