Product Description:
The XSM165-172-402-S-0KA servo motor is manufactured by Kollmorgen and belongs to the XSM Centurion Servo Motors series. It is a three-phase brushless unit intended for precision position or velocity control in automated machining centers, material-handling axes, and indexing tables. A keyed steel shaft simplifies mechanical coupling, while the high-resolution sine/cosine encoder supplies detailed feedback to the drive for tight closed-loop control. The absence of an internal brake keeps the rotating mass low for a highly dynamic response.
At the motor flange, a continuous output of 19.4 Nm provides steady-state torque without exceeding the thermal limit of the frame 165 housing. Short bursts can rise to 48.6 Nm, supporting rapid acceleration of inertial loads during cycle changes. Electromagnetic conversion efficiency is indicated by a torque constant of 0.54 Nm/A, and this ratio helps determine the required current rating of the companion inverter. The back-EMF factor is 65 V/kRPM, so the drive bus voltage must exceed that value at the highest commanded speed. The stator has a phase-to-phase inductance of 3.3 mH, which filters ripple current. Its copper resistance is 0.167 Ω, which affects resistive heating under load.
The rotor inertia is 0.00147 kg·m², permitting fast speed changes while resisting minor load disturbances. The coil insulation withstands a hipot test of 1800 VAC RMS for 1 s, providing protection against voltage transients in industrial cabinets. An 8-pole magnet array balances torque density and smooth operation, reducing cogging as the sine/cosine sensor interpolates small position increments. The motor weighs 15 kg, allowing its mass to be considered when sizing machine supports and calculating axis dynamics. It uses an M10 × 1.5 shaft thread cut to a depth of 22 mm for secure coupling. The Grade 1144 steel shaft offers good machinability for custom adapters while providing the strength needed to transmit torque to the connected load.
