Product Description:
The XSM130-50-504-S-2AA servo motor is produced by Kollmorgen within the XSM Centurion Servo Motors series. This AC rotary unit serves as the prime mover in closed-loop axes where precise velocity and position control are required on packaging lines, pick-and-place stages, and other industrial automation equipment. By combining a frame size 130 stator with matched windings, the motor converts drive current into regulated shaft torque without mechanical gearing, allowing direct-drive assemblies to minimize backlash.
The motor’s nominal speed reaches 5000 rpm, enabling high surface velocities on directly coupled loads while staying within the 460 V winding rating. At this speed, the shaft can deliver 50 in-lb of continuous torque. Dynamic response benefits from a rotor inertia of only 0.00027 kg·m², so acceleration occurs rapidly when commanded through the SinCoS feedback loop. The motor has a torque constant of 0.79 Nm/A, which relates drive current to mechanical output. Its back electromotive force voltage constant is 96 V/krpm, indicating the counter-electromotive force seen by the amplifier during regeneration. These electrical values help the drive regulate current while remaining within the available bus voltage.
Electrical response is governed by a phase inductance of 21 mH and a winding resistance of 2.5 Ω. These values affect current rise time and copper losses that must be managed by the control loops. Eight stator poles provide synchronous commutation, so the unit pairs with digital drives that support an 8-pole profile. The motor uses a smooth 1144 steel shaft without a keyway. A brake interface adds 1.91 inches to the overall length when the 24 V holding brake is fitted. The overall mass remains modest at 5.9 kg, simplifying integration into gantries or robotic arms while keeping moving inertia low.
