Product Description:

The XSM100-27-502-E2-0AA is a brushless servo motor produced by Kollmorgen as part of the XSM Centurion Servo Motors series. This frame-mounted unit converts drive current into controlled rotary motion for positioning axes, indexing tables, and light conveyor sections in automated machines. An eight-pole electromagnetic structure and an incremental encoder supply the feedback required by digital drives to close the velocity and position loops. The motor is supplied without an integral brake, making it suitable for systems that rely on external holding devices when the axis is stationary.

With a frame size of 100 and an overall length of 189.3 mm, the motor weighs 3.6 kg, allowing compact mounting in confined spaces. The shaft can reach up to 5000 rpm with the rated 230 VAC supply while producing 27 in-lb of continuous torque. Electromagnetic conversion is supported by a torque constant of 0.40 Nm/A, a phase resistance of 1.8 ohms, and a phase inductance of 12 mH. The incremental encoder produces 2,000 pulses per revolution, providing real-time position data for servo control. An M5 × 0.8 mm shaft thread supports secure attachment to pulleys or precision collets.

The motor supports a maximum radial load of 69 kg at 1000 rpm, permitting direct belt tensioning without supplementary bearings. Dynamic response is aided by a rotor inertia of only 0.00009 kg·m², enabling fast acceleration with modest drive current. The back-EMF profile has a constant of 52 V/kRPM, providing predictable voltage generation during regenerative braking. The coil insulation withstands test voltages up to 1800 VAC RMS, supporting safe operation in grounded systems. Kollmorgen applies the standard options build code to this model, so cable exits, seals, and connector orientations use the default Centurion configuration.
