Product Description:
The LSM100-35-454-M-0KA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. As a rotary actuator, it delivers commanded torque and speed to automated axes in packaging lines, gantry stages, and material-handling fixtures. The unit is supplied without an integral holding brake, so an external mechanism or drive-applied torque is required when a stationary load must be secured. Its high-resolution multi-turn absolute encoder supplies precise position data to the drive controller, allowing closed-loop motion to resume after a power cycle without repeating a homing routine.
The motor delivers a continuous torque of 4.0 Nm when mounted to a suitable heat-dissipating surface. During acceleration or shock loading, it can reach a peak torque of 16 Nm for short periods, giving machinery the additional force needed to overcome inertial or frictional loads. Mechanical output reaches a maximum speed of 4500 rpm, establishing the highest operating speed without overspeeding the rotor. Reaching peak output can draw up to 22.6 A peak from the drive, so conductors and protective devices must accommodate that transient load. A rotor inertia of 0.000144 kg·m² supports quick velocity changes while helping the axis settle smoothly after rapid positioning movements.
At zero speed, the winding requires 5.0 A peak to maintain the rated stall torque, providing a baseline for current-loop adjustment. The windings are designed for a 460 V DC bus, matching common three-phase power systems and permitting long cable runs with moderate losses. A torque constant of 0.86 Nm/A links drive current to mechanical output, supporting feedforward calculations in precise control loops. The motor has a phase inductance of 16.8 mH, which works with the 5.9 Ω winding resistance to shape current rise time. These electrical characteristics also influence pulse-width modulation frequency selection and help the drive limit electrical noise during rapid torque commands.
