Product Description:

The AKM73S-ACC2R-03 is a brushless servo motor in the AKM Synchronous Servo Motors series from Kollmorgen. It is intended for position and velocity control tasks in industrial automation, where direct coupling to precision machinery benefits from its electromagnetic torque output and feedback interface. By combining compact dimensions with matched feedback, the unit supports closed-loop motion axes in packaging, printing, and assembly equipment. Its design is suited to applications that require repeatable motion, stable speed regulation, and accurate response to changing load conditions.

Its integrated 24 V holding brake engages automatically when power is removed, keeping the load stationary without external clamping. Power and feedback connections exit through 2 SpeedTec Ready connectors, a layout that supports quick keyed engagement and organized cable routing. Rotor position is measured by a resolver, whose analog signals remain reliable in electrically noisy and high-temperature environments. The resolver inside this motor is implemented as a single-turn inductive device with two poles, giving absolute position within one mechanical revolution for accurate commutation. The motor uses a 188 mm frame, allowing installation in IEC-based machine layouts with minimal adapter hardware.

To match application torque and inertia targets, the design uses rotor length index 3, which helps balance thermal capacity and dynamic response. Output torque is transferred through a shaft with a precision-ground keyway, simplifying coupling to gearboxes or pulleys while helping prevent slip when the brake is applied. The windings use a special winding arrangement that supports operation with drives outside the standard AKM voltage tables. Mounting interfaces comply with an IEC accuracy N flange arrangement, which helps maintain alignment during installation. This combination of brake, feedback, shaft, and mounting features supports steady operation in repetitive start-stop motion and continuous positioning duty.
