XSM115-55-352-S-2AA by Kollmorgen

The Kollmorgen XSM115-55-352-S-2AA is a high-performance servo motor from the XSM Centurion Servo Motors series by Kollmorgen. Designed for industrial automation, this compact unit delivers a peak torque of 19.8 Nm and a continuous torque of 6.2 Nm at a 230 Volt class supply. Weighing just 5.5 kg, it balances power density with a lightweight design ideal for space-constrained installations. Its rotor inertia of 0.00038 kg·m² ensures rapid dynamic response and precise motion control. Maintenance-free construction guarantees extended operational life and minimal downtime.

Featuring advanced electrical and mechanical characteristics, this servo motor offers a back EMF constant (ke) of 76 Volts/kRPM and a torque constant (kt) of 0.6 Nm/Amp, ensuring linear torque output proportional to current input. The winding inductance of 7.5 mH (phase-to-phase) and winding resistance of 1.3 Ohms (phase-to-phase @ 25°C) have been optimized for smooth current control and reduced heat generation under varying load conditions. A robust shaft design incorporates an M6 x 1.0 mm thread size with a 16 mm thread depth, facilitating secure coupling to gearboxes, encoders, and load interfaces. The motor’s ability to withstand severe torque spikes without performance degradation underscores its reliability in demanding environments.

Operational features emphasize consistent, quiet performance and minimal maintenance requirements. The maintenance-free design eliminates the need for periodic bearing or seal replacements, reducing lifecycle costs and service interruptions. Effective heat dissipation is achieved through a thermally conductive housing and precision-wound stator, ensuring thermal stability under sustained loading. Its smooth electromagnetic design minimizes vibration and acoustic noise, making it suitable for applications where low noise is critical. Symmetric winding behavior and balanced rotor dynamics allow continuous operation under over-duty cycles without risk of thermal overload.

Integration is straightforward thanks to standard industrial mounting dimensions and compatibility with common feedback devices and drives. The motor’s electrical interface conforms to 230 Volt class systems, simplifying retrofit into existing control architectures. Compact size and standardized shaft configuration enable seamless incorporation into robotic arms, pick-and-place systems, packaging machinery, and CNC platforms. With its combination of high torque density, precision control constants, and robust construction, the XSM115-55-352-S-2AA is an ideal solution for performance-critical industrial automation applications.
