Product Description:
The XSM165-95-404-S-0KA is a brushless servo motor manufactured by Kollmorgen for the XSM Centurion Servo Motors series. As a mid-frame member of this product group, it supplies closed-loop rotary motion for indexing tables, pick-and-place heads, and general automation axes. The motor couples electromagnetic torque to a 28.0 mm keyed shaft, allowing position controllers to command repeatable movement with positive engagement at the coupling. Its brushless design reduces wear associated with mechanical commutation and supports frequent changes in speed and direction. A compatible servo drive regulates current according to feedback from the motor, maintaining accurate position and velocity under changing loads.
Rated continuous torque reaches 95 in-lb, allowing the shaft to handle moderate load moments without overheating. A maximum speed of 4000 rpm supports short cycle times while remaining within the operating limits of the resolver and bearings. The windings are designed for a line voltage of 460 V, making the unit suitable for many North American servo amplifiers. System responsiveness benefits from a rotor inertia of 0.00078 kg·m², which helps minimize settling time after rapid acceleration. The torque constant is 1.07 Nm/A, providing a fixed relationship between motor current and generated torque for current-loop tuning. Winding resistance is 1.49 Ω, and winding inductance is 27 mH; these electrical values affect current ripple and filter selection.
The housing supports axial loads up to 67 kg and radial loads up to 127 kg at 1000 rpm, accommodating belt-pulley or gear-pinion arrangements without external support bearings. A 165.0 mm bolt circle, a 130 mm pilot, and a 22 mm thread depth support secure face mounting. The overall length is 233 mm, which limits the installation depth required behind the mounting surface. Electrical feedback is provided by a SinCos encoder, giving the drive continuous sine-and-cosine signals for position and speed control. No brake is installed, so static holding torque must come from the drive or an external mechanical device. The motor generates back EMF at 130 V/krpm, a value used when evaluating bus voltage and regenerated energy. The motor weighs 9.8 kg, providing a manageable mass for mounting on multi-axis gantries and other automated machinery.
