Product Description:

The XSM100-27-352-M-0AA belongs to the XSM Centurion Servo Motors series produced by Kollmorgen. This brushless servo motor provides position and velocity control in automation cells by transmitting precise shaft rotation to actuators and gearboxes. The motor is supplied without a brake, so an external mechanism must prevent unwanted movement when the axis is not energized. A multi-turn feedback device reports the absolute shaft position to the drive, supporting coordinated motion without requiring the axis to establish its position after each power cycle. Frame size 100 indicates the square flange envelope, while the motor operates from a 230 V supply.

Continuous mechanical output is available at speeds up to 3500 rpm, and the rated torque reaches 27 in-lb, allowing the drive to supply the current required by the connected load. The torque constant is 0.56 Nm/A, so each ampere of phase current produces slightly more than half a newton-meter of torque. A phase inductance of 24 mH moderates the rate at which current rises through the windings during changes in the drive command. The phase resistance is 3.9 ohms, which contributes to copper losses and winding heat during continuous operation. A voltage constant of 72 V/krpm relates the generated back electromotive force to shaft speed, helping the controller regulate current as motor speed increases.

The mounting face has a bolt circle of 100 mm with 7.0 mm mounting holes, providing a secure connection to a machine plate or gearbox. A pilot diameter of 80 mm centers the housing accurately in the mating surface and helps maintain shaft alignment. The ground shaft has a diameter of 16.0 mm and includes an M5 × 0.8 mm tapped thread for drawbar retention. An overall motor length of 189.3 mm supports installation in compact machine assemblies where axial clearance is limited. The motor has a mass of 3.6 kg, which helps limit the weight carried by moving axes while providing a stable housing for the rotor, bearings, and feedback components.
