Product Description:
The LSM100-46-454-E2-2KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. It is built for closed-loop positioning and velocity control in industrial automation. Its rapid response and repeatable torque support precise load movement on assembly lines, packaging machines, and robotic systems.
This motor delivers a continuous torque of 5.2 Nm, allowing it to hold steady loads without overheating, while a peak torque of 16 Nm supports short acceleration bursts. Its rated speed reaches 4500 rpm, so high-throughput motion profiles can be executed without gear reduction. During stall, the windings draw 6.4 A(pk), and the torque constant of 0.88 Nm/A relates drive current to shaft torque for straightforward gain tuning. The drive may supply up to 21.2 A(pk) for dynamic moves, and the eight rotor poles synchronize with the stator’s electronic commutation to minimize cogging. The copper windings have a resistance of 3.9 Ω and an inductance of 12.44 mH, which the amplifier uses when regulating its current loops. A metric M5 × 0.8 threaded shaft end accepts standard couplings or pulleys and provides a secure connection to the driven equipment.
For holding functions, an integral brake operates on 24 VDC and increases reflected inertia to 0.0002 kg·m², compared with 0.00017 kg·m² when the rotor spins freely. Position feedback is generated by a quadrature encoder with 2000 lines, providing fine resolution for closed-loop position and velocity control. The back-EMF constant is 106 V/kRPM, helping the drive anticipate voltage demand as motor speed rises. The motor has a total mass of 7.1 kg, including the brake assembly, which must be considered when sizing the machine mounting surface. The integrated brake can hold the connected load when commanded, while the encoder supplies the motion controller with incremental position data during operation.
