Product Description:

The XSM165-172-404-M-2KA servo motor is manufactured by Kollmorgen as part of the XSM Centurion Servo Motors series. Designed for industrial automation, the motor interfaces with a servo drive to deliver commanded torque and velocity to rotary mechanisms such as pick-and-place heads, feed rollers, and rotary tables. Its closed-loop design allows machine controllers to position loads with repeatable precision, coordinate multiple axes, and shorten operating cycles without the mechanical backlash associated with gear reductions. The unit combines a permanent-magnet rotor with a stator optimized for high power density, making it suitable for applications with limited space on mechanical frames.

The motor reaches a rated speed of 4000 rpm, supporting drive platforms that modulate frequency for medium- and high-speed motion tasks. A 24 V brake locks the shaft when power is removed, preventing vertical or suspended loads from drifting. The mounting holes are arranged on a 165.0 mm bolt circle, providing compatibility with corresponding NEMA-equivalent mounting interfaces. The windings withstand a hipot test of 2350 VAC, indicating sufficient insulation strength for mains-powered installations. The magnetic circuit has a phase inductance of 13 mH, which moderates current rise, reduces thermal stress on the drive, and supports smooth torque production during rapid acceleration.

The feedback channel uses a multi-turn encoder that delivers absolute position data across multiple revolutions, eliminating the need for homing after power-up. Dynamic response is influenced by a rotor inertia of 0.00147 kg·m², balancing rapid acceleration with stable tracking at commanded velocities. The motor generates back electromotive force at a constant of 130 V/krpm, which the drive uses when calculating voltage limits during field weakening. The copper windings have a phase resistance of 0.65 Ω, which affects steady-state current draw and supports thermal modeling for continuous-duty operation.
