Product Description:
The XSM115-53-502-S-2AA servo motor is produced by Kollmorgen within the XSM Centurion Servo Motors series. It is an AC permanent-magnet unit intended for closed-loop motion axes in packaging, pick-and-place, and indexing machinery. The motor supplies mid-range torque and integrates into machinery that uses other Centurion motors across multiple frame sizes.
With a frame size of 115 and an overall length of 211.1 mm, the motor occupies a compact envelope for machine assemblies. It delivers 53 in-lb of continuous torque, which supports moderate-duty servo axes without gearbox multiplication. The shaft has a diameter of 19.0 mm, allowing direct connection to standard metric hubs. At 1000 rpm, the shaft can carry a radial load of up to 84 kg and an axial load of up to 39 kg without reducing the expected bearing life. The rated speed reaches 5000 rpm, allowing high-throughput positioning over short move distances. A factory-installed 24 V brake secures the axis during a power loss, while the motor weight of 5.5 kg supports installation on gantries and other moving assemblies. The motor uses standard options without special flanges or seals.
The winding is designed for a 230 V bus and provides a torque sensitivity of 0.41 Nm/A, giving digital drives predictable current requirements. Back EMF increases at 50 V/krpm, supporting consistent velocity measurement across the operating speed range. Dynamic response is aided by a rotor inertia of 0.00038 kg-m². The winding has an inductance of 3.3 mH, allowing the current control loop to respond quickly to changing torque commands. Its resistance of 0.64 Ω limits steady-state resistive heating during continuous operation. SinCos feedback supplies position information to the controller for closed-loop speed and motion control. The feedback signal enables the connected drive to monitor rotor movement and correct deviations caused by changing loads. The permanent-magnet rotor and low electrical time constant support responsive acceleration and deceleration in repetitive automation cycles.
