Internal Product Review
The XSM100-37-502-M-2AA is a Kollmorgen Centurion servo motor rated for 5000 RPM and 37 in-lb torque. Multiturn feedback and a 24 Volt brake support accurate positioning and controlled stopping in demanding motion applications. Low rotor inertia of 0.00011 kg-m2 gives this motor especially sharp dynamic response.

Product Description:
The XSM100-37-502-M-2AA is a servo motor produced by Kollmorgen for the XSM Centurion Servo Motors series. Within automated assembly, packaging, and material-handling cells, this AC motor delivers controlled rotary motion to position loads rapidly and repeatably. It has a frame size of 100, placing it in the mid-frame class commonly used for compact, high-torque drive axes. As a Centurion model, it pairs with compatible digital drives and multi-turn feedback devices to close the position loop without external encoders.
The shaft can reach 5000 rpm, a speed ceiling suited to indexing tables and high-speed pick-and-place heads. Continuous torque capability is 37 in-lb, and the electromagnetic design converts current into torque with a constant of 0.40 Nm/A. This torque constant helps the drive predict load response for precise velocity regulation. Back electromotive force rises at 52 V/krpm, so a drive sized for the motor’s 230 V winding can recover energy during deceleration without exceeding its DC-bus rating. The permissible radial load is 74 kg at 1000 rpm, helping protect the bearing set when pulleys or gears overhang the flange. Multi-turn feedback retains absolute position data after power loss, which allows the system to resume operation without performing a homing cycle.
Electrical characteristics include a phase inductance of 7.5 mH, which filters ripple current, and a winding resistance of 1.2 ohms, which contributes to copper losses at rated load. The rotor’s low inertia of 0.00011 kg-m² supports rapid acceleration, while the assembly mass of 4.6 kg limits the moving load on gantry or robot joints. A 24 V brake is available and holds the shaft when power is removed. Installing the brake extends the motor length by 1.368 inches. The smooth shaft has no keyway and accepts an M5 × 0.8 mm mounting thread with a depth of 12.5 mm. Its shaft design maintains alignment when connected through clamp-style hubs.
