Product Description:

The AKM42J-ACC2C-00 is a permanent-magnet servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. It is intended for industrial automation tasks that demand accurate bidirectional torque, allowing a drive controller to position loads quickly and repeatably in assembly stations, electronic packaging lines, and multi-axis gantries. By combining a compact electromagnetic core with low-inertia rotor laminations, the motor translates digital current commands from the drive into real-time rotary motion that stays synchronized with feedback for tight process control.

The unit incorporates a 24 V holding brake that secures the shaft when power is removed, preventing backdriving on vertical or safety-critical axes. Power and feedback are routed through 2 SpeedTec Ready connectors; the bayonet design shortens installation time and provides a vibration-resistant lock. Rotor position is monitored by a Kollmorgen SFD feedback device that transmits incremental and commutation data over 4 lines, and its accuracy is maintained by a single-turn inductive resolver that is immune to magnetic stray fields. The frame body measures 84 mm across the mounting pilot. The front face uses an IEC flange with accuracy N, so the motor bolts directly to standard gearboxes or machine plates without adapters.

Shaft power is transferred through a hardened steel hub that includes a keyway for positive torque transmission to couplings or pulleys. The stacked iron core is built to the J winding designation, giving the torque constant associated with that coil set while keeping copper losses within drive limits. Mechanical length corresponds to Rotor Length Index 2, providing a balance between continuous torque capability and overall mass so machine builders can achieve dynamic acceleration without exceeding payload constraints.
