Product Description:

The AKM42E-GNC2R-00 is a synchronous servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. It is intended for closed-loop positioning and velocity regulation in automated machinery, where accurate torque generation and rapid response are required to coordinate tooling, conveyors, or robot joints. When paired with a compatible drive, the motor supports precise motion control during repeated starts, stops, and speed changes. This type of motor is commonly used where a controller must maintain stable speed at varying loads without excessive lag. Its synchronous design helps the commanded position track the motion profile closely during cycle-to-cycle operation.

An integrated 24 V holding brake locks the rotor when power is removed, preventing load drift on vertical or suspended axes. Quick installation is supported by 2 SpeedTec Ready connectors, which separate power and feedback lines and use bayonet latching for secure attachment. Separating these connections helps keep wiring orderly in compact machine layouts. Rotor position is measured by a resolver, whose analog sine-cosine signals tolerate electrical noise and high temperatures. Its electrical feedback uses 2 poles, aligning the resolver cycle with the motor’s magnetic field for smooth commutation. The square housing has an 84 mm frame dimension that fits standard IEC size 80 mounting patterns. A standard customization level, single-turn inductive feedback, and a feedback package classified as size 10/15/21 complete the control interface.

An alternative flange variant G provides a different bolt circle to match legacy gearboxes or linear actuators, while a smooth shaft permits clamp couplings without keyways for minimal runout. A smooth shaft also supports clamping elements that rely on even contact around the shaft surface. The medium magnetic circuit produced by rotor length index 2 balances inertia and continuous torque for mid-range duty cycles. Winding designation e pairs that rotor with drive outputs suited to moderate bus voltages. This rotor and winding combination is aimed at balanced dynamic response for motion axes that require steady operation and a consistent electrical interface.
