XSM130-73-404-M-0AA by Kollmorgen

The XSM130-73-404-M-0AA is a brushless motor manufactured by Kollmorgen within the XSM Centurion Servo Motors series. It is intended for integration into industrial automation where closed-loop drive amplifiers command the stator windings to generate tightly regulated torque and speed on rotary axes. The model is supplied without an integral holding brake, its shaft is smooth without a keyway, and a 16 AWG power lead is specified for field wiring.

Under continuous duty the motor delivers 8.2 Nm while maintaining the rated shaft speed of 4000 rpm; this combination allows sustained mechanical output without overheating. A continuous stall current of 9.9 A is required at the terminals to hold that torque when the rotor is locked, and thermal sizing of the drive must consider this figure. The motor has a torque constant of 0.95 Nm/A, indicating nearly one newton-meter of torque per ampere. Power is supplied from a 460 V AC bus, matching common factory mains for high-power servo axes. During rotation the winding generates a back electromotive force of 115 V/kRPM, a parameter used by the drive to predict commutation voltages and to limit regenerative overvoltage during rapid deceleration.

For transient events such as indexing moves or accelerations, peak torque rises to 20.3 Nm, allowing short bursts of force well above the continuous rating before thermal limits are reached. The rotor inertia is held to 0.00041 kg-m², enabling responsive speed changes without excessive control effort. Electrical dynamics are influenced by a phase-to-phase inductance of 18 mH, which filters current ripple and affects switch-frequency selection in the drive amplifier. Multi-turn absolute feedback is integrated for position reporting across power cycles, and the assembly weighs 7.3 kg, simplifying installation on moderate-sized gantries or indexing tables.
