Product Description:
The XSM215-531-304-M-0KA belongs to the XSM Centurion Servo Motors series produced by Kollmorgen. It is an AC brushless servo motor designed for closed-loop positioning and speed control in industrial automation systems. The motor supports applications that require high continuous torque and direct mounting to heavy mechanical loads.
This model draws a continuous stall current of 48.0 A, which is the steady-state current the drive must supply when the shaft is locked under rated thermal conditions. Stator copper losses are influenced by a winding resistance of 0.189 Ω, while an inductance of 5.5 mH shapes current ripple and affects the current-loop bandwidth in the drive electronics. A voltage constant of 168 V/krpm indicates the back EMF generated per thousand revolutions per minute. This value helps determine the required DC-bus voltage so the amplifier can achieve the commanded speed without saturation. Dynamic response is aided by a rotor inertia of 0.00775 kg·m², allowing rapid acceleration while providing enough rotational mass for smooth velocity regulation at low speeds.
The shaft can support up to 47 kg of axial load at 3000 rpm and up to 160 kg of radial load at the same speed, enabling direct coupling to belts, gears, or lead screws without auxiliary support bearings. The rated operating speed is 3000 rpm, matching many standard servo drives and keeping surface velocity within bearing limits. The motor weighs 40.25 kg, so suitable lifting hardware is recommended during mounting. The keyed shaft has an M12 × 1.75 mm central thread with a thread depth of 28 mm, providing attachment points for couplings and retention hardware. Because the motor does not have an internal brake, the connected gearbox or an external clamping device must provide holding torque when the shaft is stationary.
