XSM115-42-504-M-2AA by Kollmorgen

The Kollmorgen XSM115-42-504-M-2AA brushless servo motor from the XSM Centurion Servo Motors series represents a high-performance solution for industrial automation and precise motion control. Manufactured by Kollmorgen, this model delivers a Peak Torque of 13.5 Nm alongside a Continuous Torque of 4.7 Nm, ensuring reliable operation under sustained loads. The motor’s torque constant (Kt) of 0.83 Nm/A and back EMF constant (Ke) of 100 V/kRPM provide predictable electrical-to-mechanical conversion for tight torque regulation. A built-in multi-turn absolute encoder eliminates homing routines and guarantees accurate position feedback across multiple revolutions. This robust design, weighing 4.3 kg, integrates seamlessly into complex automation systems without additional support structures.

Detailed technical specifications define the XSM115-42-504-M-2AA’s capability envelope with precision. The phase-to-phase winding inductance of 21 mH and winding resistance of 3.8 Ohm @25 °C enable consistent current control and minimal thermal drift. The motor is rated for a Voltage Class of 460 Volt, supporting high-voltage drive architectures. A Rotor Inertia of 0.00026 kg·m² facilitates rapid acceleration and deceleration cycles. Dimensional interface tolerances of +0.0004/–0.0002 in on the shaft and thread hole specifications of M6 × 1.0 mm; depth 16 mm ensure repeatable mounting geometry. Insulation meets Class-F rating, providing high dielectric strength under demanding conditions.

Operational features highlight system performance and mechanical resilience. The XSM115-42-504-M-2AA sustains axial loads up to 78 kg at 1000 RPM, 62 kg at 2000 RPM, 51 kg at 3500 RPM, and 45 kg at 5000 RPM, supporting vertical or cantilevered shaft applications. Its low inertia and high torque density deliver precise motion profiles for synchronous multi-axis systems. A keyless brake operating at 24 VDC secures the shaft in emergency or power-off states, enhancing safety. The combination of high-resolution absolute feedback and robust electrical constants allows for stable closed-loop control even under variable speed and load conditions.

System integration is straightforward with standard 1144 steel shaft construction and industrial connectivity. The XSM115-42-504-M-2AA is optimized for use with Kollmorgen drives, PLCs, and motion controllers in robotic assembly, CNC machining, and material handling applications. Its multi-turn absolute encoder and Class-F insulation make it suitable for environments requiring long-term reliability and minimal maintenance. This servo motor excels in high-precision automation tasks, from semiconductor equipment to precision packaging lines.
