Product Description:
The LSM130-78-454-E2-2KA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. As a rotary actuator, it supplies commanded torque and speed to automated machinery that requires precise motion control. The motor converts drive current into mechanical output through a permanent-magnet rotor, while its feedback system allows the drive to regulate position during operation. This combination supports controlled movement in indexing tables, pick-and-place heads, material-handling equipment, and other automated axes that require accurate speed and position adjustments.
Under continuous load, the motor delivers 8.8 Nm of torque while maintaining a rated shaft speed of 4500 rpm. Its continuous current is 10.7 A, while acceleration and other short-duration demands can draw a peak current of 50.9 A. The copper windings have a resistance of 1.68 Ω and an inductance of 8.46 mH, which affect current response and compatible drive selection. A torque constant of 0.88 Nm/A relates the applied current to the resulting motor torque. The back electromotive force constant is 107 V/kRPM, indicating the voltage generated as rotational speed increases. Position feedback is supplied by a 2000-line incremental encoder, giving the drive detailed movement information for closed-loop control. A 24 VDC brake circuit provides static holding when the motor shaft must remain stationary.
For short operating intervals, the shaft can produce a peak torque of 38 Nm to support rapid acceleration or temporary load changes. The rotor has an inertia of 0.00049 kg·m², balancing responsive speed changes with rotational stability under load. The motor has an overall mass of 11.2 kg, which must be considered when sizing machine supports and mounting surfaces. Mechanical attachment is provided by an M8 × 1.25 mm threaded shaft hole with a depth of 19 mm, allowing compatible tie rods or couplings to be secured. The motor housing and mounting interface should be aligned carefully to avoid imposing excessive radial or axial loads on the bearings during operation.
