Product Description:
Kollmorgen manufactures the XSM100-27-502-M-2AA servo motor within the XSM Centurion Servo Motors series. This model belongs to the Centurion product group and uses a frame size 100 housing that fits midsize machine axes. As a brushless AC unit, it supplies rotational power to positioning tables, pick-and-place heads, and packaging spindles that require accurate closed-loop motion. The motor is supplied with multi-turn feedback, allowing the drive to track absolute shaft position over multiple revolutions without an external homing routine.
The winding has a base speed of 5000 rpm, allowing rapid traverses while keeping the electrical frequency compatible with 230 V class drives. At the rated current, the motor produces 27 in-lb of continuous torque, which supports the acceleration of moderate-inertia loads. The electromagnetic design provides a torque constant of 0.40 Nm/A, helping the controller convert measured phase current into output torque. Back electromotive force rises at 52 V/krpm, so the drive must accommodate the resulting voltage at peak speed. A line-to-line voltage rating of 230 V matches common industrial power systems and reduces the need for a step-up transformer.
A factory-installed 24 V brake clamps the shaft during power loss, helping prevent movement on vertical axes. The shaft has no keyway, so torque is transmitted through a friction coupling secured with an M5 × 0.8 mm thread that extends 12.5 mm into the shaft nose. The stator windings have an inductance of 12 mH, which affects current rise time and drive current-loop response. A phase resistance of 1.8 ohms also influences electrical losses and controller tuning. The rotor has a low inertia of 0.00009 kg-m², improving responsiveness when the direction of rotation changes. The assembly has a net mass of 3.6 kg, which limits the added load when the motor is mounted on a gantry or robotic arm.
