Product Description:
Kollmorgen produces the XSM165-172-402-M-2KA servo motor as part of the XSM Centurion Servo Motors series. This motor is intended for precision motion axes in industrial automation, where closed-loop speed and position control improve throughput and repeatability. The 165-frame unit fits medium-sized machinery and supports multi-turn absolute feedback, allowing the drive to retain the shaft position after a power cycle.
The motor delivers a continuous shaft torque of 19.4 Nm when cooled under rated conditions, allowing steady operation without thermal derating. For rapid acceleration, it can supply a peak torque of 48.6 Nm, providing additional force to overcome inertia during indexing moves. Its electromagnetic design produces a torque constant of 0.54 Nm/A, indicating the relationship between supplied current and generated torque. Back electromotive force measured at the leads is characterized by a voltage constant of 65 V/kRPM, enabling the controller to calculate suitable commutation voltages throughout the operating range. With a rotor inertia of 0.00147 kg-m², the motor balances fast response with stable speed regulation on loads that change direction frequently.
The bearings sustain a radial shaft load of 143 kg and an axial shaft load of 48 kg at 1,000 rpm, allowing couplings and pulleys to be mounted without external supports. The internal three-phase windings have a resistance of 0.167 ohms, which limits conductor losses and affects the current needed to generate torque. Their inductance of 3.3 mH establishes the electrical time constant that the drive must overcome with adequate voltage slew during field-oriented control. The optional 24-volt brake adds only 2.03 inches to the motor’s overall length. The motor also has a keyed shaft and eight magnetic poles. Its M10 × 1.5 threaded hole has a depth of 22 mm, supporting attachment to compatible transmission hardware.
