Product Description:
The XSM115-42-502-E2-2AA is a servo motor manufactured by Kollmorgen and supplied under the XSM Centurion Servo Motors series. Designed for closed-loop positioning and speed regulation, it integrates into industrial automation axes that require repeatable motion profiles. An incremental encoder provides feedback to the connected drive or controller for precise commutation and position verification. The encoder produces 2,000 pulses per revolution, giving the control system detailed information about rotor movement during operation.
The unit reaches a top speed of 5000 rpm, and at this operating point, it can generate a continuous shaft torque of 42 in-lb. Its torque constant is 0.41 Nm/A, allowing the required drive current to be calculated from the load torque. The phase-to-phase resistance is 1.0 Ω, which affects conductor heating during continuous operation, while the motor has an electrical rating of 230 V. The motor has a frame size of 115 and a pilot diameter of 95 mm. A 115 mm bolt circle aligns the housing with compatible gearboxes or machine plates. The output shaft has a diameter of 19.0 mm and an internal M6 × 1.0 mm thread extending to a depth of 16 mm, providing a secure coupling interface.
At rated speed, the shaft accepts a radial load of 45 kg and an axial load of 25 kg when no radial component is present. The phase-to-phase inductance is 5.6 mH, which influences winding current response and drive behavior. Generated back electromotive force follows a voltage constant of 52 V/krpm, providing an important value for matching the motor to a compatible servo drive. An optional 24 V brake adds 1.91 inches to the overall motor length and provides static holding capability when power is removed. This configuration uses standard options, so the housing dimensions, mounting interfaces, and shaft thread do not require special modifications.
