Product Description:
The LSM100-35-454-R-0KA is a brushless servo motor produced by Kollmorgen in the LSM Brushless Servo Motors series. It is intended for closed-loop industrial automation where coordinated position and speed control are required, such as indexing tables or packaging axes. By combining a permanent-magnet rotor with stator windings designed for sinusoidal commutation, the unit converts drive current into rotary motion with high accuracy and repeatability. It is built for precise servo duty in industrial machines.
This model delivers a continuous output torque of 4.0 Nm, allowing it to maintain load without overheating during steady operation, and it can reach a peak of 16 Nm for short dynamic events like acceleration or impact loads. The rated speed is 4500 rpm, so mechanical transmission ratios can be minimized while retaining fast cycle times. To support these figures, the drive may supply up to 22.6 A of peak phase current, while the stall current is 5.0 A. With a torque constant of 0.86 Nm/A, commanded current translates into predictable torque for tight current-loop regulation. The magnetic circuit contains 8 rotor poles, which sets the electrical frequency required for synchronous operation.
An unloaded rotor inertia of 0.000144 kg·m² promotes quick start-stop profiles and limits overshoot in high-gain position loops. Back electromotive force is characterized by a voltage constant of 103 V/kRPM, which supports velocity estimation and field weakening. The 3-phase windings exhibit an inductance of 16.8 mH and a resistance of 5.9 Ω, which affect current rise time and thermal loss. The amplifier uses these electrical values to shape current response during rapid command changes. Radial bearing load capacity is 56 kg at 1000 rpm, while the net mass is 5.3 kg. The shaft is made of ST-60 steel to resist fatigue under cyclic torque.
