Product Description:

The LSM23N-12-602-E1-0KA is a brushless servo motor manufactured by Kollmorgen for the LSM Brushless Servo Motors series. In industrial automation, it serves as the rotary actuator that a matched drive commands for precise speed, torque, and position control on conveyor lanes, pick-and-place heads, or small indexing tables. By integrating incremental feedback and a low-inertia rotor, the device converts electrical power into controlled mechanical motion that repeats cycle after cycle with minimal positional error.

The motor delivers a continuous torque of 1.4 Nm without exceeding its thermal limits, while its peak torque reaches 5.6 Nm for short acceleration bursts. The stall current is 4.1 A, which helps determine the appropriate current limit in the drive. The motor has a rated voltage of 230 VAC, allowing its stator windings to operate with a compatible servo drive. The torque constant is 0.36 Nm/A, enabling the drive to estimate shaft torque from the applied phase current. Position data are returned through a 1000-line incremental encoder, providing 4000 counts per revolution when quadrature decoding is used for closed-loop positioning.

The winding has an inductance of 13.0 mH and a resistance of 3.68 Ω, which influence current ripple and the selection of a suitable PWM switching frequency. Back EMF develops at 43 V/kRPM, so the drive must provide additional voltage headroom during high-speed operation. Dynamic response is aided by a rotor inertia of 0.000023 kg·m², allowing rapid velocity changes with limited control effort. The housing measures 130 mm from the mounting face to the end bell, while the motor weighs 1.8 kg for installation on lightweight gantries. The 0.375-inch shaft has a machined keyway that provides positive torque transmission to pulleys or gearheads.
