Product Description:
The LSM165-173-304-M-0KA is a brushless servo motor manufactured by Kollmorgen and assigned to the LSM Brushless Servo Motors series. As a rotary actuator, it delivers commanded torque and speed to machine axes in automation cells, packaging lines, and material-handling stations. The motor operates with a compatible drive connected to a 460 VAC bus. A multi-turn absolute encoder reports the shaft position, allowing the controller to maintain closed-loop awareness of the mechanical angle during coordinated motion. This feedback also allows the drive to regulate speed and position without requiring the motor to complete a homing cycle after each power interruption.
The motor delivers a continuous torque of 19.5 Nm at a nominal speed of 3000 rpm. Its 1.29 Nm/A torque constant provides the relationship between supplied current and generated torque. As the shaft rotates, the motor produces a back electromotive force of 156 V/kRPM, which the drive accounts for during field-oriented control and regenerative operation. During rapid acceleration, the windings can draw up to 72.1 A peak. The insulation system is suitable for operation with a 460 VAC drive bus. The motor weighs 18.7 kg and has a housing length of 330 mm, providing the physical dimensions needed for machine layout and mounting clearance.
Short-duration dynamic loads are supported by a peak torque of 75 Nm. The rotor has an inertia of 0.00128 kg·m², supporting responsive acceleration while allowing the connected load to be matched to the servo system. Electrical response is influenced by a winding inductance of 9.6 mH and a winding resistance of 0.98 Ω, which the drive uses when regulating current and applying short-circuit protection. At standstill, the motor can hold a stationary load with a peak stall current of 16.5 A. Mechanical attachment is provided by M10 × 1.5 mm mounting holes with a thread depth of 22 mm. These threaded mounting points allow the motor housing to be secured directly to a compatible machine frame or mounting plate.
