Product Description:

The Kollmorgen XSM165-172-404-S-2KA Servo Motor is a high torque precision motor. It supports efficient motion control with low winding resistance and high peak torque output. It is ideal for demanding applications needing stable operation and compact design.

The XSM165-172-404-S-2KA servo motor from the XSM Centurion offers a peak torque of 48.6 Nm (430 lb in) and a continuous torque of 19.4 Nm (172 lb in) that is suitable for high load applications. The rotor inertia is 0.00147 kgm² (0.013 lb·in·s²) which supports fast acceleration and deceleration. It has a weight of 15.0 kg (33.0 lb). The torque constant of the servo motor is rated at 1.07 Nm/Amp while the voltage constant is 130 Volts/Krpm that enables high responsiveness and energy efficiency. Winding resistance is measured at 0.65 ohms and the motor features a phase to phase winding inductance of 13 mH. The motor is engineered with durability and consistent performance in mind. It operates efficiently at 460 volts. The compact construction of the motor reduces installation space while delivering high torque performance. Its weight to torque ratio is optimized for balancing power and manageability.

The XSM165-172-404-S-2KA servo motor includes a Cannon TNM 16-19, 192993-0110 encoder connector and a Cannon TNM 16-4, 192993-0106 power connector that ensures secure and efficient electrical connections. The construction of the motor ensures thermal efficiency and reduced losses under operational load. Its shaft sealing system supports extended lifespan and dust resistance. The shaft seal kit for the motor is M.1301.9161 with dimensions of 30 mm inside diameter, 72 mm outside diameter and 8 mm width. It supports precise control even in dynamic loads with reduced mechanical vibrations and improved energy transmission due to its neodymium magnet rotor.
