Product Description:

The AKM42J-ACCN2-00 is a brushless AC servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. It is engineered for closed-loop positioning and velocity control, and it couples directly to precision machinery while transmitting commanded torque with low rotor inertia. In automated assembly cells, packaging lines, and semiconductor handling stations, the unit serves as the rotary actuator that follows drive-generated motion profiles with repeatable accuracy.

For mechanical integration, the motor is delivered without a brake, so any load-holding function must be provided by the drive or by an external locking device. Two power and feedback leads exit through two SpeedTec Ready connectors, permitting tool-free quarter-turn mating and quick cable connection. Rotor position is detected by a Comcoder that supplies incremental and commutation signals at a native resolution of 2048 lines/rev, enabling tight servo loop bandwidth. The front face measures 84 mm square, allowing the motor to fit into compact multi-axis stages while still delivering moderate continuous torque. Thermal balance and electrical constants are set by the J winding, which matches typical 230-VAC drives.

The feedback chain is reinforced by a single-turn optical feedback track, eliminating cumulative turn count errors during rapid reversals. Its code wheel follows the EPC 15T format, so the connected drive can read absolute commutation vectors immediately after power-up. Mounting accuracy is governed by an IEC flange with accuracy N, providing consistent pilot centering for repeatable shaft alignment. Torque is transferred through a keyway shaft, a detail that simplifies coupling to pulleys, gearboxes, or rigid hubs without relying on friction alone. The rotor length index 2 supports a compact motor length for general-purpose automation axes.
