Product Description:

Kollmorgen manufactures the XSM165-172-404-S-2KA brushless servo motor as part of the XSM Centurion Servo Motors series. This rotary actuator provides precise velocity and position control for industrial automation when paired with a compatible drive. Its moderate frame dimensions and high torque density make it suitable for indexing tables, feeders, and similar motion axes that require responsive acceleration and repeatable movement.

The motor delivers a continuous stall torque of 19.4 Nm with forced-convection cooling, and producing that torque requires a winding current of 20.5 A. Its torque constant is 1.07 Nm/A, allowing the drive electronics to calculate current demand across the operating range. The rated speed is 4000 rpm, supporting continuous operation at elevated shaft speeds before the back EMF approaches the available bus voltage. The voltage constant is 130 V/krpm. Electrical response is influenced by a phase inductance of 13 mH and a winding resistance of 0.65 Ω, which affect drive bandwidth and copper losses. The frame size 165 housing accepts a 14 AWG power lead, while the optional 24 V holding brake increases the overall motor length by 2.03 inches without changing the mounting registers.

The motor supports a peak torque of 48.6 Nm up to a corner speed of 2000 rpm, providing additional output during acceleration and other short dynamic events. At 1000 rpm, the bearing arrangement permits a maximum radial load of 143 kg; with no radial load applied, it also permits an opposing axial load of 67 kg at the same speed. Mechanical output is transmitted through a keyed shaft with an M10 × 1.5-6H central thread, which accepts locking hardware to a depth of 22 mm and helps secure the connected coupling during directional reversals.
