Product Description:
The LSM54-3-602-E1-0KA brushless servo motor is manufactured by Kollmorgen as part of the LSM Brushless Servo Motors series. Designed for compact automation stages, it converts electrical power into precise rotary motion that can be commanded in velocity or position mode. A built-in optical encoder provides rotor-angle feedback, allowing the connected controller to maintain tight tolerances during indexing, dispensing, or micromachining operations.
This model delivers a continuous torque of 0.33 Nm, providing a stable force range for steady-state cutting or feeding operations, while a maximum speed of 6000 rpm supports rapid movement between work points. The motor can draw up to 3.8 A peak when the application demands short bursts, and its peak torque reaches 1.32 Nm before magnetic saturation limits further loading. An incremental feedback disk provides 1000 lines per revolution, giving the controller sufficient resolution for smooth motion interpolation. The torque constant is 0.35 Nm/A, and the peak stall current is 1 A when the winding remains energized without shaft rotation. The back electromotive force constant is 43 V/krpm, indicating how much countervoltage is generated as rotational speed increases.
The shaft can accept a radial load of 20 kg at full speed, and the motor has 8 poles for finely stepped electronic commutation. Its low rotor inertia of 0.0000029 kg·m² supports rapid reversals and responsive acceleration, while the motor has a net mass of 0.7 kg to reduce the load on moving carriages. The motor operates from a single-phase 230 VAC supply that is compatible with many light-duty servo amplifiers. Its steel shaft resists fretting under repeated coupling loads and directional changes. The copper windings have an inductance of 57.5 mH and a resistance of 30.29 Ω, allowing the drive to regulate current and estimate winding temperature rise during operation.
