Product Description:

The LSM165-119-454-M-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It supplies tightly regulated rotary power to automated machinery where coordinated motion, accurate speed tracking, and repeatable positioning are required. A multi-turn absolute encoder on the rear of the frame delivers position data to the drive so the axis can be synchronized with other plant devices.

The motor delivers a continuous shaft output of 13.5 Nm, ensuring sustained load support without excessive heating when operated from the rated supply of 460 VAC. Its windings permit a top mechanical speed of 4500 rpm, so transmission ratios can be reduced while still achieving fast cycle times. With a torque constant of 0.87 Nm/A, the drive can calculate the phase current required for the requested torque. A phase inductance of 6.68 mH influences the current ripple that must be filtered by the inverter. At standstill, the motor draws a peak current of 16.4 A, a value used to size the drive’s continuous current channel. The winding resistance is 0.76 Ω, and feedback signals are transmitted through the absolute encoder interface.

For transient moves, the actuator can reach a peak torque of 51 Nm while accepting a maximum phase current of 70.7 A. These operating limits allow acceleration of high-inertia loads without loss of synchronization. The rotor’s moment of inertia is 0.00092 kg·m², balancing fast response with mechanical stability when coupled to gearboxes or pulleys. The total assembly mass is 16.2 kg, which affects mounting hardware selection and the dynamic load placed on support structures. The shaft end has an M10 × 1.5 threaded hole with a depth of 22 mm, enabling secure attachment of couplings or timing-belt hubs. A voltage constant of 105 V/krpm allows the drive to account for back electromotive force during field-oriented control.
