Product Description:

The XSM115-53-502-M-2AA is a brushless servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. Serving as a rotary actuator in automated assembly lines, the unit converts drive current into controlled shaft rotation, allowing motion controllers to command speed, position, and holding force with repeatability. Its multi-turn encoder supplies absolute position data through multiple revolutions, simplifying homing and supporting coordinated multi-axis machinery.

Under continuous operation, the motor reaches a rated speed of 5000 rpm, allowing fast indexing without mechanical gear reduction. At that speed, it can deliver up to 53 in-lb of output torque with a torque constant of 0.41 Nm/A. Dynamic response is aided by the low rotor inertia of 0.00038 kg·m², which limits overshoot during rapid acceleration. The shaft and bearings can sustain an axial thrust of 51 kg and a radial side load of 84 kg at 1000 rpm, supporting belt-driven and pulley-driven applications. Loads applied to the shaft must remain within these limits to avoid excessive stress on the bearings during operation.

The motor uses a size 115 frame pattern with a 115 mm bolt circle, a 95 mm pilot, and 10.0 mm mounting holes, supporting direct flange attachment to compatible gearboxes. Its 19.0 mm shaft is tapped with an M6 × 1.0 mm thread to a depth of 16 mm for secure coupling. The optional brake adds 1.91 inches to the motor’s overall length. When installed, the 24 V brake engages automatically after power is removed to hold the shaft in position. The windings are rated for a nominal bus voltage of 230 V, making the motor compatible with drives that use this voltage class. The assembly weighs 5.5 kg, which reduces the load placed on compact gantries and mounting structures. Standard design and accessory options are used, so the motor retains the corresponding external dimensions and connector arrangement for the Centurion product group.
