Product Description:
The XSM215-425-304-M-0KA is a brushless servo motor produced by Kollmorgen within the XSM Centurion Servo Motors series. Designed for servo loops that demand quick acceleration and stable velocity, the unit converts electrical power into controlled mechanical rotation for machine tools, pick-and-place heads, and packaging axes. Its 215-frame stator, keyway shaft, and 1144-steel construction allow direct coupling to gear reducers or belt drives while maintaining alignment under repeated reversals.
During continuous stall conditions, the motor draws 38.5 A, indicating the current the drive must supply while the rotor is locked and rated torque is required. Once motion begins, it reaches a nominal shaft speed of 3000 rpm, ensuring compatibility with drive stages that use a standard 1 kHz commutation frequency. The phase resistance is 0.254 Ω, and the back EMF increases by 168 V/krpm; these electrical constants guide drive selection and regenerative braking limits. When rapid indexing is needed, the motor can deliver a peak torque of 101.1 Nm at the published peak corner speed of 2000 rpm, providing capacity for load surges without exceeding thermal limits. The 7.2 mH inductance smooths current transitions, reducing ripple and audible noise.
A rotor inertia of 0.0058 kg-m² supports fast settling without excessive overshoot, while the housing has a net weight of 35 kg and a shipping weight of 36.8 kg. The insulation system withstands a hipot test of 2350 VAC, and the motor has 8 poles that support its commutation sequence. No brake is installed, so static holding torque must be provided by the drive or an external actuator. The 28 mm-deep M12 × 1.75 thread in the 1144-steel shaft simplifies chuck or coupling attachment. The keyed shaft carries the continuous 42 in-lb rating with capacity up to 425 lb-in during peak operation.
