Product Description:
The XSM115-53-502-E2-0AA is a brushless AC servo motor manufactured by Kollmorgen as part of the XSM Centurion Servo Motors series. It is designed for industrial automation systems that require precise regulation of position, velocity, and torque. When connected to a compatible servo drive, the motor can control packaging equipment, electronics assembly machinery, and light material-handling axes that operate with frequent starts, stops, and changes in speed.
The motor provides a continuous shaft output of 53 in-lb and can operate at speeds up to 5000 rpm. Its 0.41 Nm/A torque constant establishes the relationship between supplied current and mechanical torque, while its voltage constant of 50 V/kRPM indicates the back electromotive force generated as rotational speed increases. The winding is designed to operate from a 230 V bus. A phase resistance of 0.64 ohm supports predictable calculations of copper loss and thermal rise under sustained loading. The winding inductance is 3.3 mH, allowing the drive to regulate current during rapid motion commands without excessive electrical delay. A rotor inertia of 0.00038 kg·m² supports responsive acceleration and deceleration in dynamic applications. Position feedback comes from an incremental encoder that produces 2000 pulses per revolution, giving the connected drive detailed motion information for closed-loop control.
The housing uses frame size 115 and has an overall length of 211.1 mm. Its net mass is 5.5 kg, which is appropriate for a mid-frame motor with this output capacity. The shaft has a diameter of 19 mm and does not include a keyway, so a suitable clamping coupling can transfer torque to the driven component. An M6 × 1.0 mm center thread extends 16 mm into the shaft and provides an axial attachment point. The motor does not have a holding brake, so an external brake or drive-supplied holding torque is required when a stationary load must remain secured. At 1000 rpm, the bearing system supports an axial load of 39 kg and a radial load of 84 kg, accommodating common belt-driven and direct-coupled arrangements.
