Product Description:
The XSM115-42-502-S-0AA is a brushless servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. As a component in positioning axes, it converts drive current into rotary motion with tightly controlled speed and torque for packaging lines, pick-and-place robots, and similar automation tasks. The unit is supplied without an internal holding brake, making it suitable for systems that use external clamping or rely on drive torque to hold position.
With a frame size of 115, the housing matches Kollmorgen’s midrange mounting pattern. The shaft reaches a maximum speed of 5000 rpm, allowing fast indexing on conveyors and pick stations. Continuous torque is rated at 42 in-lb, providing output for moderate loads. The stator windings are designed for a 230 V bus, and their 5.6 mH phase inductance smooths current transitions, helping the drive maintain steady torque. SinCos feedback returns high-resolution position data to the controller for accurate closed-loop operation. The bearings support radial and axial loads of 78 kg and 36 kg, respectively, at 1000 rpm. The 19.0 mm shaft has an M6 × 1.0 mm thread that is 16 mm deep for puller or coupling hardware. The overall length is 185.7 mm, helping the motor fit installations with limited enclosure depth.
Dynamic response is supported by a rotor inertia of 0.00026 kg·m², keeping acceleration times low while allowing stable control. The motor has a torque constant of 0.41 Nm/A, providing predictable torque for each ampere of current. Its back-EMF constant is 52 V/krpm, which the drive uses when calculating field-oriented control limits. Phase resistance is 1.0 Ω, helping keep winding temperature manageable near the rated current. The motor weighs 4.2 kg, which facilitates handling during installation while providing sufficient mass for mechanical damping.
