Product Description:

The LSM215-451-204-S-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. Designed for closed-loop motion axes in automated machinery, the unit converts electrical power into precisely regulated shaft rotation. Positioning controllers can use this controlled motion to execute accurate velocity and torque profiles on conveyors, presses, or robotic joints.

During continuous operation, the motor can sustain 51 Nm of torque while spinning at up to 2000 rpm, giving system planners a predictable torque-speed envelope for high-duty cycles. Its stator windings are optimized for a three-phase bus of 460 VAC, and a winding constant of 1.84 Nm/A means each ampere of drive current produces nearly two newton-meters of shaft torque. Peak electrical demand reaches 106.1 A(pk), so power modules must accommodate this transient draw. A rotor inertia of 0.0060 kg·m² balances quick acceleration with mechanical stability, helping servo loops limit overshoot during fast indexing moves. Single-turn, high-resolution sine-cosine feedback supplies the drive with absolute position data. The machined case depth from the mounting face measures 372 mm, providing a reference for cabinet or gearbox layouts.

When rapid load changes occur, the motor can deliver a maximum torque of 158 Nm. At standstill, the windings tolerate 29.7 A(pk) without loss of synchronism, providing a safety margin for holding or clamping duties. The assembly weighs 38.5 kg, which influences mounting hardware and vibration isolation choices. Electrical characteristics used for thermal modeling include a voltage constant of 222 V/kRPM, a phase inductance of 10.0 mH, and a phase resistance of 0.50 Ω. An M12 × 1.75 mm shaft thread is cut to a depth of 28 mm, allowing standard retention hardware to secure the rotor end.
