Product Description:
The XSM215-531-304-M-2KA is a brushless servo motor engineered by Kollmorgen for the XSM Centurion Servo Motors series. In automated assembly cells, pick-and-place gantries, and coordinated packaging axes, the unit generates repeatable rotary motion while reporting absolute position through its high-resolution multi-turn absolute feedback device. The 215-frame housing provides a compact form for integration into industrial machinery. A shaft fitted with a keyway allows direct coupling to compatible gearboxes, pulleys, and other driven components without relying solely on friction-based connections.
Continuous output is sustained with a phase current of 48.0 A, and each ampere of drive current produces 1.39 Nm/A of torque through the motor’s electromagnetic design. Electrical loading is shaped by a winding inductance of 5.5 mH and a phase resistance of 0.19 Ω; these values affect current rise time and stator power loss. A rotor inertia of 0.00773 kg-m² balances responsive acceleration with stable speed control. The motor develops 53 lb-in of continuous torque for normal duty cycles, while its 531 lb-in peak torque accommodates brief increases in mechanical load. The shaft can reach a rated speed of 3000 rpm, and the voltage constant is 168 V/krpm. This electrical profile allows a compatible servo drive to regulate torque and speed across demanding motion cycles.
A factory-installed 24 V brake holds the connected load whenever the controller disables motor torque. The brake assembly adds 3.5 in to the motor’s overall length, which must be considered when establishing axial clearance inside the machine. Power leads exit the stator through an 8 AWG cable that carries the full-load current while limiting voltage drop. The shaft has an M12 × 1.75 mm thread with a depth of 28.0 mm, providing secure retention for compatible mechanical components. Operation below the 1500 rpm corner speed supports efficient torque production before increasing back EMF begins to restrict the available voltage margin from the drive bus.
