Product Description:

The XSM100-37-502-E2-0AA is a brushless servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. The motor supplies closed-loop rotary power to packaging, indexing, and conveyor axes in industrial automation. It fits a 100-frame housing and is supplied without a holding brake, so an external mechanical stop can be added when required. A smooth shaft without a keyway simplifies connection to zero-backlash clamping couplings. The incremental encoder on the rear flange sends position data to the drive for precise motion control.

The motor draws a continuous stall current of 12.0 A, allowing it to hold load torque during continuous air-cooled operation. This current produces a continuous stall torque of 37 in-lb, providing steady rotary force for medium-duty webs and pick-and-place heads. The rotor has a moment of inertia of 0.00011 kg·m², which supports rapid acceleration and deceleration during repetitive motion. A base speed of 5000 rpm provides a broad operating range for high-speed automation. The phase windings have an inductance of 7.5 mH, which limits the rate of current change and supports stable current regulation by the drive.

The motor has a back EMF constant of 52 V/krpm, allowing the drive to account for generated voltage as shaft speed changes. Its torque constant is 0.40 Nm/A, providing a predictable relationship between commanded phase current and mechanical output. The winding resistance is 1.2 ohms, which affects resistive heating during continuous operation. The motor operates with a DC-link voltage of 230 V, making it suitable for compatible servo amplifiers that use this bus level. The incremental encoder produces 2,000 pulses per revolution and supplies 8,000 counts per revolution when its quadrature outputs are decoded. The threaded shaft end has an M5 × 0.8 mm thread with a depth of 12.5 mm, which accommodates compatible puller hardware. The complete motor assembly weighs 4.6 kg with standard options.
