Product Description:
The XSM115-58-504-S-2AA is a servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. The unit converts electrical energy into controlled rotary motion for positioning axes, conveyors, and indexing tables in automated machinery. Its 115 mm square frame supports installation with midrange gearheads and machine plates. SinCos feedback supplies high-resolution rotor data to the drive, enabling precise velocity and position control during rapid or repetitive motion. This feedback arrangement also allows the drive to monitor shaft movement and correct deviations caused by changing loads.
Rated output torque reaches 58 in-lb, allowing the motor to handle moderate inertial loads without excessive overshoot. Continuous operation at speeds up to 5000 RPM supports equipment that requires rapid cycles and quick acceleration. The motor has a torque constant of 0.83 Nm/A, indicating how much shaft torque is produced for each ampere of stator current. Its voltage constant is 100 V/krpm, so the required drive voltage rises in proportion to motor speed. A rated input voltage of 460 V is compatible with common industrial power systems and helps limit current in the connected power cables. These operating values allow a compatible servo drive to regulate torque and speed across the intended working range without relying on unnecessary mechanical modifications.
A 24 V mechanical brake clamps the shaft when power is removed, helping prevent vertical axes from drifting. The encoder subsystem operates from a dedicated +9 VDC supply provided by the drive, supporting stable feedback signals during operation. The windings have an inductance of 13 mH, which helps filter switching ripple from the drive output. Phase resistance is 2.4 ohms, and this resistance contributes to copper losses and winding heat under load. The electrical characteristics should be considered when matching the motor with a servo amplifier and setting current limits. Proper drive matching also supports consistent acceleration, controlled stopping, and accurate position holding throughout repeated production cycles. The standard motor configuration does not add specialized shaft, flange, or sealing features beyond the stated arrangement.
