Product Description:

The AKM11B-ANC2R-00 is a brushless AC servo motor manufactured by Kollmorgen and supplied as part of the AKM Synchronous Servo Motors series. This motor serves as the prime mover for compact automation axes, converting controlled stator currents into precise rotary motion for pick-and-place heads, metering pumps, and small material-handling stages. When paired with a digital servo drive, it delivers closed-loop speed, torque, and position regulation, enabling fast cycle times and repeatable motion in semiconductor tools, light packaging equipment, and laboratory devices.

Mechanical holding is provided by a 24 V holding brake, allowing the shaft to remain locked when power is removed so vertical loads are not back-driven. Field wiring is streamlined by two SpeedTec-ready connectors that separate power and feedback lines while maintaining keyed, tool-free coupling. Rotor position is measured with a resolver, giving analog sine-cosine signals that remain tolerant of heat and vibration. The motor seats against an IEC flange with accuracy class N, which supports interchange with IEC-pattern gearheads without bracket rework. Its 40 mm frame size keeps the package compact for tightly spaced machine layouts.

The output end uses a smooth shaft so couplings or pulleys can be installed without a keyway, which can help reduce concentricity error during high-speed cycles. Position information is based on a 2-pole feedback design, and its single-turn inductive topology avoids mechanical gear sets that can wear or slip over time. Electromagnetic behavior follows winding designation B, which sets resistance and inductance values matched to low-voltage servo drives. A rotor length index of 1 keeps inertia low for quick response, and the standard customization level supports consistency across similar AKM motor builds.
