Product Description:
The AKM31C-ANSNS-02 is a compact servo motor produced by Kollmorgen for the AKM Synchronous Servo Motors series. This rotary unit acts as a torque source in positioning stages, pick-and-place heads, and small indexing tables where fast, closed-loop motion is required. Its compact housing supports installation in space-limited machinery, while its electromagnetic design provides responsive acceleration and precise velocity control when paired with a compatible digital drive. The permanent-magnet motor converts regulated electrical current into controlled rotary motion for applications that require frequent starts, stops, and direction changes.
The motor is supplied without a brake, so drive torque or an external clamping device must hold the load when power is removed. A 70 mm frame dimension provides a square mounting interface suitable for compatible IEC gearheads and machine plates. The IEC flange with accuracy N maintains the concentricity needed for repeatable alignment between the motor shaft and the connected load. Internally, the stator uses winding designation C, which corresponds to the resistance and inductance profile required by compatible Kollmorgen drives in the mid-voltage range. Power and feedback leads exit through a special connector arrangement that combines both circuits in a keyed housing, helping prevent incorrect connections during installation. The connector layout also keeps cable routing compact around closely spaced machine components.
Position signals are provided through a special feedback arrangement that supplies high-resolution data to the controller and supports accurate closed-loop regulation. The motor uses rotor length index 1, balancing inertia and torque for controlled acceleration of small loads without excessive overshoot. Output torque is transmitted through a smooth shaft, which accepts clamp-style couplings or press-fit gears without requiring a keyway. The motor’s low-cogging design promotes smooth rotation at low speeds, while efficient internal heat paths help maintain stable operation during demanding duty cycles. These characteristics support precise motion in compact automation equipment where smooth torque delivery and responsive control are important.
