Product Description:

Kollmorgen manufactures the XSM100-27-502-M-0AA as part of the XSM Centurion Servo Motors series. This brushless servo motor converts drive current into controlled shaft motion for positioning or speed-regulated duties in automated cells, allowing compact machines to move loads smoothly without overshoot. It belongs to the Centurion product group and is intended for mid-power motion axes that require precise feedback control.

The windings are rated for 230 V, so standard industrial inverters can energize the motor directly. Under continuous stall conditions, the phase current reaches 9.0 A, establishing the thermal sizing point for the drive. The design permits a maximum speed of 5000 rpm, and the shaft can deliver 27 in-lb of torque. A torque constant of 0.40 Nm/A relates the commanded current to the torque produced by the motor. The back-EMF constant of 52 V/krpm indicates the voltage returned to the drive during regeneration. The three-phase stator has a winding resistance of 1.8 Ω, and the aluminum housing helps dissipate heat generated during prolonged operation.

Frame size 100 provides a square mounting face with M5 × 0.8 mm threaded holes that are 12.5 mm deep for direct flange attachment. The rotor has a moment of inertia of 0.00009 kg·m², supporting quick acceleration without excessive overshoot. The electrical inductance is 12 mH, which helps smooth current at high switching frequencies. The shaft bearings tolerate a radial load of 40 kg and an axial load of 13 kg at rated speed. A multi-turn feedback encoder reports absolute position across multiple revolutions, allowing the controller to retain position information beyond a single shaft rotation. No holding brake is installed, so static holding torque must be supplied by the drive or external mechanics. The motor weighs 3.6 kg, which supports installation on light- to medium-payload motion axes without adding excessive machine mass.
