Product Description:

The AKM42J-EKCN2-00 is a brushless AC servo motor manufactured by Kollmorgen and assigned to the AKM Synchronous Servo Motors series. In automated machinery, it supplies tightly regulated torque and speed so that motion controllers can position loads accurately over repeated cycles. Its design focuses on high feedback fidelity and mechanical flexibility, allowing quick mounting and straightforward integration with Kollmorgen servo drives in packaging lines, robotics, and material-handling equipment.

The motor has a frame dimension of 84 mm, which sets the square flange size for compatibility with gearboxes and mounting plates. A shaft machined with an open keyway allows couplings to transmit torque without slip or additional locking hardware. Because the model is supplied without a brake, holding torque during power-off must be provided by the drive or an external mechanism. Electrical and feedback wiring are routed through two SpeedTec Ready connectors, which use bayonet latches to shorten installation time and maintain UL-recognized sealing. Position data are generated by an incremental encoder that delivers 2048 lines/rev, giving motion controllers fine resolution for velocity loops and accurate positioning during slow moves.

Additional characteristics refine how the motor interfaces with the drive electronics. The J winding is matched to drive tables that set current limits for this thermal class, and rotor length index 2 gives a medium magnetic stack that balances inertia and continuous torque. Feedback is handled by a Comcoder, a combined Hall and optical device that returns incremental signals on a single channel. Its tracking span is single-turn optical, so absolute position is maintained over one mechanical revolution. The sensor format is EPC 15T, which matches Kollmorgen's standard servo drive pinout. The customization level is standard, so the motor is delivered with standard seals, bearings, and paint for general factory environments.
