Product Description:
The LSM130-78-454-E2-0KA is an AC brushless servo motor built by Kollmorgen for the LSM Brushless Servo Motors series. As a rotary actuator for industrial automation, it converts drive current into controlled mechanical torque, allowing machine tools, positioning tables, or packaging axes to follow programmed motion profiles. Its design pairs permanent-magnet excitation with encoder feedback so that a matching Kollmorgen drive can regulate torque, speed, or position in real time. The unit supports applications that require high peak output without sacrificing continuous-duty capability.
During steady operation, the motor supplies 8.8 Nm of continuous torque while maintaining the coil temperature within its operating limit. The speed limit is 4500 rpm, based on mechanical balance and back EMF. To reach the commanded acceleration, the drive may deliver up to 50.9 A peak, and the magnetic coupling converts that current to torque at a rate of 0.88 Nm/A. The voltage constant is 107 V/1000 rpm, indicating the back EMF generated per thousand revolutions, so a 400 V DC link leaves voltage margin for control. A stall current of 10.7 A peak applies when the rotor is stopped but the windings remain energized. The resistance of 1.68 Ω and inductance of 8.46 mH establish electrical time constants that influence current-loop behavior. A keyed shaft transmits torque directly to couplings or pulleys.
For short bursts, the motor can deliver 38.0 Nm, which supports rapid indexing and helps overcome static loads. Dynamic response is aided by a rotor inertia of 0.00041 kg·m², balancing low overshoot with adequate load matching. Four front-face holes tapped for M8 × 1.25 mm fasteners simplify installation, and each hole has a thread depth of 19 mm. An optical feedback device provides 2000 lines of incremental resolution to the controller, supporting accurate position and speed measurements. The total mass is 10.0 kg, so the mounting structure must support the motor while limiting vibration during acceleration, deceleration, and continuous operation.
