XSM165-172-404-M-2KA by Kollmorgen

The XSM165-172-404-M-2KA servo motor from Kollmorgen is a high-performance member of the XSM Centurion Servo Motors series designed for demanding industrial automation applications. This robust unit delivers a continuous torque of 19.4 Nm and an impressive peak torque of 48.6 Nm, ensuring responsive power delivery and precise motion control. Weighing just 15 kg, it maintains a compact footprint with a diameter of 28 mm and offers versatile mounting options. The motor’s design prioritizes torque density and dynamic responsiveness, making it ideal for high-precision positioning tasks.

Featuring advanced electrical characteristics, the XSM165-172-404-M-2KA provides a torque constant (Kt) of 1.07 Nm/A and a voltage constant (Ke) of 130 V/krpm, facilitating efficient conversion of electrical energy into mechanical output. Its winding inductance of 13 mH minimizes ripple torque and electromagnetic interference, while a winding resistance of 0.65 Ohms ensures stable performance under varying loads. The motor’s rotor inertia of 0.00147 kg-m² contributes to excellent dynamic response and precise speed regulation. With overall lengths of 283.8 mm in brake configuration and 233 mm without brake, the motor fits seamlessly into both compact and more spacious assemblies.

Operational reliability is enhanced by the motor’s capacity to withstand substantial axial loads, supporting up to 143 kg at 1000 rpm and 90 kg at 4000 rpm, thus accommodating a range of shaft-mounted components. Embedded temperature sensors within the stator windings enable real-time thermal monitoring and intelligent shutdown to prevent overheating. The standardized M10 x 1.5 shaft thread with 22 mm shaft thread depth simplifies direct coupling to gearboxes, pulleys, or encoders, reducing assembly complexity and slippage risks. Its efficient stator construction promotes effective heat dissipation for continuous operation in high-duty-cycle environments.

Integration into existing systems is straightforward: the XSM165-172-404-M-2KA interfaces seamlessly with Kollmorgen servo drives and controllers, leveraging standardized electrical and mechanical connections. Its compact form factor and dual-length options allow customization for space-constrained machine tools or large-scale automated lines. Typical applications include precision robotics, CNC machining centers, packaging equipment, and semiconductor handling systems. With its blend of high torque density, thermal intelligence, and mounting flexibility, this servo motor is a versatile solution for next-generation industrial automation.
