Product Description:
The XSM100-27-352-S-2AA is produced by Kollmorgen for the XSM Centurion Servo Motors series. As a rotary actuator for positioning and velocity control, it interfaces with drives that read SinCos feedback for high-resolution commutation. Its frame size 100 housing supports compatibility with common IEC flange patterns, while the 230-volt winding class suits mid-power machinery in assembly lines, electronics packaging, and automated inspection stations.
The motor reaches a rated speed of 3500 rpm and delivers up to 27 in-lb of continuous torque to couplings or gearheads. Its torque constant is 0.56 Nm/A, allowing moderate phase current to produce the required shaft load. The winding is designed for a 230 V bus and has a phase resistance of 3.9 ohms. A corresponding inductance of 24 mH affects the current rise time and drive filter requirements. Back EMF develops at a rate of 72 V/krpm, establishing the voltage margin that the inverter must accommodate during dynamic deceleration. The rotor inertia is 0.00009 kg·m², allowing the axis to accelerate rapidly with controlled motion during pick-and-place or indexing cycles that require frequent starts and stops.
A factory-installed 24 V brake adds 1.368 inches to the motor’s overall length. The brake locks the shaft when control power is removed, which helps prevent unintended movement when the axis is stationary. Axial retention reaches 49 kg, and radial capacity is 87 kg at 500 rpm, allowing the shaft to support belt or pulley loads without additional bearings. The motor has a net mass of 3.6 kg, making its weight suitable for compact automated equipment. The front face has M5 × 0.8 mm mounting threads with a depth of 12.5 mm for secure attachment to the machine or mounting plate.
