XSM165-95-404-S-2KA by Kollmorgen

The Kollmorgen XSM165-95-404-S-2KA is a high-performance industrial servo motor from the XSM Centurion Servo Motors series by Kollmorgen designed for demanding automation tasks. This compact yet powerful unit delivers a peak torque of 23.2 Nm and a continuous torque rating of 10.7 Nm, providing smooth and reliable motion control. With a mounting flange dimension of 165 mm and a weight of 9.8 kg, it integrates seamlessly into existing equipment while maintaining a robust footprint. The motor’s shaft diameter of 28.0 mm and precision-machined keyway ensure secure mechanical coupling and efficient torque transfer.

Technical excellence is built into every aspect of the XSM165-95-404-S-2KA. Featuring a voltage class of 460 Volt, it achieves rapid responsiveness with a torque constant (Kt) of 1.07 Nm/A and a voltage constant (Ke) of 130 V/kRPM. The winding inductance of 27 mH and winding resistance of 1.49 Ohms (phase to phase at 25°C) are optimized for low electrical losses and precise current control. Its rotor inertia of 0.00078 kg·m² supports high acceleration profiles, while the bolt circle dimension of 143.5 mm ensures compatibility with standard drive train interfaces. Length variations to accommodate auxiliary components include 233 mm without brake and 283.8 mm with 24 VDC brake, giving system designers flexibility in cabinet layout.

Operational reliability is reinforced by robust mechanical and thermal characteristics. The motor can sustain an axial load force up to 42 kg at 1000 rpm without compromising performance or service life. The precision SinCos feedback system delivers high-resolution position and speed data, enabling sub-micron accuracy and tight loop control. Under regular operating speeds up to 3000 rpm and a maximum speed of 4000 rpm, the XSM165-95-404-S-2KA maintains stable torque output with minimal vibration. Its integrated key size of 8 x 7 x 40 mm ensures dependable torque transfer even under peak loads, while the standardized frame reduces installation time and simplifies maintenance.

Integration into complex automation architectures is straightforward thanks to standardized mechanics and clear electrical characteristics. The mounting flange dimension of 165 mm and bolt circle dimension of 143.5 mm match industry norms, facilitating drop-in replacement and retrofit applications. Ideal for packaging lines, robotic arms, CNC machinery, and material handling systems, this servo motor offers scalable performance from high-precision indexing to heavy-duty positioning. Combined with Kollmorgen drives and motion controllers, the XSM165-95-404-S-2KA provides a turnkey solution for optimizing throughput, accuracy, and system uptime.
