Product Description:
The XSM115-42-502-M-0AA is a brushless permanent-magnet servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. It converts controlled current from a servo amplifier into precise rotary motion for industrial machinery. Its high-response operation supports tight position and speed regulation in indexing tables, feeders, and other automated axes.
This model reaches a top shaft speed of 5000 rpm, allowing fast cycle completion when paired with a compatible drive. Its continuous stall torque is rated at 42 in-lb, providing moderate rotary force for medium-frame actuators supplied from a 230 V bus. The motor has a torque constant of 0.41 Nm/A, so stator current produces output torque at a consistent rate. The phase winding has an inductance of 5.6 mH, which affects current rise time and current-loop bandwidth. Its winding resistance is 1.0 Ω, a value that determines copper loss under a steady load. A multi-turn feedback device supplies absolute position data to the controller, allowing the drive to retain position information across multiple shaft revolutions. The motor is supplied without a holding brake, reducing its mass and rotor load. Its frame-size 115 housing and standard configuration support installation where available space and payload are limited. The motor has a net weight of 4.2 kg, which should be considered when selecting mounting hardware and support structures.
The motor supports an axial load of 51 kg and a radial load of 78 kg at 1000 rpm, permitting direct pulley or belt loading without auxiliary bearings. Dynamic performance is supported by a rotor inertia of 0.00026 kg·m², allowing quick acceleration while maintaining smooth low-speed control. The voltage constant is 52 V/kRPM, indicating the back electromotive force generated as shaft speed increases. The 19.0 mm shaft includes an M6 × 1.0 mm end thread with a depth of 16 mm, simplifying attachment to gearheads, couplings, or load hubs. Correct alignment of the shaft and driven component helps prevent unnecessary radial loading during operation. The permitted axial and radial forces should be evaluated together when belts, pulleys, or offset couplings apply combined loads to the motor shaft.
