Product Description:
The XSM115-42-502-E2-0AA is a brushless servo motor manufactured by Kollmorgen within the XSM Centurion Servo Motors series. Designed for closed-loop positioning tasks, the unit converts drive current into controlled rotary motion for indexing tables, pick-and-place actuators, and other automation axes. It accepts power from a matched servo amplifier and returns position data through its incremental encoder, allowing the controller to correct velocity or angular errors in real time. This feedback arrangement supports accurate movement during repeated acceleration, positioning, and stopping cycles.
A mounting flange for frame size 115 provides a standardized bolt circle for coupling the motor to gearboxes or direct-drive loads. The winding supports a maximum speed of 5000 rpm, allowing rapid traverse moves without overshoot. Continuous stall output reaches 42 in-lb of torque, providing stable force for holding or slowly moving loads. The motor has a torque constant of 0.41 Nm/A, so every ampere of phase current produces just under half a newton-meter at the shaft. Copper loss at the rated temperature is affected by a phase resistance of 1.0 Ω, which assists with current-loop tuning and thermal modeling inside the servo drive. The electrical characteristics allow a compatible amplifier to regulate torque across both low-speed holding tasks and faster positioning movements.
When radial force is applied at the shaft centerline, the bearings tolerate up to 78 kg at 1000 rpm. Simultaneous axial thrust can reach 51 kg without shortening the expected bearing service life. A rotor inertia of 0.00026 kg-m² provides quick acceleration while retaining enough momentum to smooth minor torque ripple. The attached incremental encoder generates 2000 pulses per revolution, enabling the drive to interpolate fine position steps and maintain accurate feedback during motion. The motor also has a phase inductance of 5.6 mH and a voltage constant of 52 V/kRPM. An M6 × 1 thread extends 16 mm into the shaft end for secure mechanical attachment.
