Product Description:
The XSM100-27-502-S-2AA is a brushless AC servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. As part of a closed-loop axis, the unit converts drive current into precisely controlled rotary motion for pick-and-place heads, form-fill-seal actuators, and general material-handling stations. Its electromagnetic core is optimized for mid-range inertia loads, providing a direct-coupled alternative to pneumatic cylinders in applications that require repeatability, programmable motion profiles, and digital diagnostics. The brushless design also supports frequent acceleration and deceleration without the mechanical wear associated with brushes.
The rotor can reach a top speed of 5000 rpm, while the continuous output torque is rated at 27 in-lb. The torque constant of 0.40 Nm/A relates motor current to output torque, while the back EMF constant of 52 V/krpm indicates the voltage generated as rotor speed rises. The windings have an inductance of 12 mH and a resistance of 1.8 Ω, balancing dynamic response with thermal loss during operation. The motor has a square frame measuring 100 mm, and its stainless-steel shaft is supplied without a keyway. The shaft is tapped with an M5 × 0.8 thread to a depth of 12.5 mm for coupling hardware. Nominal operation from a 230 V drive bus allows connection to compatible servo amplifiers in the Centurion product group.
The motor supports an axial thrust limit of 34 kg and a radial bearing load capacity of 87 kg at 500 rpm, permitting the use of belt tensioners or pinion gears without premature bearing wear. When holding torque is required while power is off, an optional 24 V brake can be fitted to secure the shaft. Installing this brake adds only 1.368 in to the motor’s overall length. Position data is returned by a SinCoS encoder, which supplies high-resolution feedback for accurate interpolation by the connected servo drive. This feedback allows the drive to monitor rotor position and regulate motion throughout acceleration, constant-speed operation, and deceleration.
