Product Description:
The XSM115-42-502-S-2AA servo motor is produced by Kollmorgen within the XSM Centurion Servo Motors series. As part of the Centurion platform, it functions as a permanent-magnet rotary actuator that converts drive current into controlled shaft motion for positioning axes, indexing tables, and similar automation tasks. The motor interfaces with compatible servo drives to provide precise torque and velocity control in compact machinery.
Rated output torque reaches 42 in-lb, allowing the shaft to drive couplings under continuous operation. For high-speed moves, the rotor can run at 5000 rpm, supporting applications with demanding linear speed requirements while keeping bearing losses within acceptable limits. A factory-installed 24-volt brake holds the load when power is removed. This spring-applied brake provides load retention for vertical axes and other applications that must remain stationary without motor torque. Nominal operation uses a 230 V winding that receives controlled power from a compatible inverter. The stator has a phase inductance of 5.6 mH, which filters current ripple and affects the current-loop bandwidth of the connected drive.
Dynamic response is supported by a rotor inertia of 0.00026 kg-m², helping limit overshoot during fast reversals while retaining enough rotational energy for smooth movement. Electromagnetic coupling is characterized by a torque constant of 0.41 N·m/A, while the voltage constant is 52 V/kRPM for use in servo regulator scaling. The motor uses frame size 115 and has a 19.0 mm shaft diameter for connection to compatible couplings, pulleys, or pinions. Its shaft end contains an M6 × 1.0 mm tapped hole that is 16 mm deep, and SinCoS feedback supplies position information to the servo drive. The bearings accommodate a 45 kg radial load and a 25 kg axial load at maximum speed. Phase resistance is 1.0 Ω, providing an additional electrical value for drive configuration and current regulation.
