Product Description:

The Kollmorgen XSM130-73-304-M-2AA is a servo motor with brush-free construction for durable performance. Its precision-balanced internals and vibration-damped housing contribute to smooth and quiet operation, even during demanding motion sequences. The absence of brushes reduces mechanical wear and eliminates the need for routine brush maintenance, which helps extend the motor’s service life. The motor comes with a balanced rotor and a damped housing structure that help to suppress vibrations during rapid speed changes. This allows the motor to maintain stability and control.

The XSM130-73-304-M-2AA is equipped with a winding inductance of 41 millihenries (mH), which slows the rate of current rise. This results in a dampening effect on sudden electrical transients, reduced torque ripple for smoother control. The motor has a base speed of 3000 rpm that enables adjustable performance in both steady-state and fast-paced applications. It delivers a continuous rotational force of 8.2 Nm under the rated load conditions, ensuring ample driving power for a wide range of industrial equipment. This model relies on a multiturn absolute encoder for enhanced precision, providing real-time data on positioning and velocity for fine-tuning of motor performance.

The XSM130-73-304-M-2AA features an M8 x 1.25 mm thread size at the shaft end, which provides a standardized and secure interface for mechanical coupling. The fine 1.25 mm pitch allows for precise fastening and helps prevent loosening during high-speed or high-vibration operation. This contributes to overall drivetrain stability and ensures reliable torque transmission to connected components. For efficient operation, this motor should be used within a permissible temperature range of 0 to 40°C. Its humidity tolerance is rated at 5% to 95% (non-condensing), which enables the motor to perform reliably in areas where moisture levels fluctuate.
