Product Description:

The LSM165-173-304-E2-0KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. It acts as a rotary actuator that receives regulated current from a matched drive and produces controlled torque for indexing tables, pick-and-place heads, and other precision axes in automated machinery. Integrated 2000-line incremental encoder feedback reports position and velocity to the controller so that motion profiles remain accurate under variable loads.

During continuous operation, the motor delivers 19.5 Nm of torque, a level set by the thermal limits of its windings and housing so production duty cycles can run indefinitely. At the rated speed of 3000 rpm, this torque equals about 6 kW of mechanical power. A torque constant of 1.29 Nm/A links phase current to shaft output; each ampere therefore generates 1.29 Nm, simplifying current-loop tuning. The drive may supply 72.1 A(pk) during acceleration, and the back EMF rises in proportion to the 156 V/kRPM voltage constant. These values combine with 9.6 mH inductance and 0.98 Ω resistance to determine the electrical time constant that shapes current response.

The motor tolerates short bursts of load by delivering up to 75 Nm of peak torque, a capacity used for overcoming static friction or indexing heavy fixtures without oversizing the frame. A rotor inertia of 0.00128 kg·m² balances rapid acceleration with speed stability, while the eight-pole design helps the control loop hold position with fine electrical resolution. A stall current of 16.5 A(pk) marks the threshold at which the shaft can be locked without damage. The mechanical interface is provided by a 28 mm shaft with an 8 mm key, allowing power to be transmitted through standard couplings. The overall mass is 18.7 kg, and the three-phase windings are optimized for a bus supply of 460 V, allowing direct connection to common industrial inverters.
