LSM100-35-454-S-0KA by Kollmorgen

The Kollmorgen LSM100-35-454-S-0KA is a high-performance component in the LSM Brushless Servo Motors series from Kollmorgen, engineered for demanding industrial automation tasks. This compact servo motor delivers a continuous torque of 4 Nm and a peak torque of 16 Nm, ensuring both sustained operation and rapid dynamic response. Operating at a rated maximum speed of 4500 rpm, it is optimized for high-throughput applications such as packaging, labeling, and conveyor systems. With a lightweight design of 5.3 kg (11.7 lb), the LSM100-35-454-S-0KA balances power density and ease of integration into existing equipment architectures.

The technical capabilities of this motor are underpinned by a robust 8-pole construction that enhances torque density and reduces cogging torque. Electrical parameters include a Ke voltage constant of 103 V/krpm and a torque constant (Kt) of 0.86 Nm/A, facilitating precise current-to-torque conversion. Thermal and current-handling performance are managed through a winding resistance of 5.9 Ohm (phase-to-phase @25 °C) and a winding inductance of 16.8 mH, providing a balanced trade-off between heat dissipation and dynamic response. The servo’s stall current of 5 A peak and maximum current rating of 22.6 A peak ensure reliable operation under sudden load changes. An integrated ST-60 shaft material adds mechanical robustness while maintaining minimal rotational inertia.

Operational features of the LSM100-35-454-S-0KA include a rotor moment of inertia of 0.00017 kg·m² (0.0015 lb·in·s²) and an incrementally increased inertia of 0.0002 kg·m² (0.0018 lb·in·s²) when equipped with the optional brake assembly. The motor net weight increases to 7.1 kg (15.7 lb) with this brake, offering smooth deceleration and holding torque when stationary. Its design emphasizes minimal thermal buildup, leveraging the interplay of winding resistance and inductance to support continuous operation without risk of thermal derating. High-speed stability is maintained by precise electromagnetic design, ensuring that rapid acceleration to and deceleration from 4500 rpm do not compromise positional accuracy. The combination of high torque, controlled current, and low inertia delivers exceptional repeatability in cyclic motion profiles.

Integration of the LSM100-35-454-S-0KA into complex automation systems is simplified by its standard mounting dimensions and direct-mechanical-drive compatibility. Its electrical interface supports seamless connection to Kollmorgen and third-party servo drives, facilitating system-level tuning and fieldbus integration. Application versatility ranges from rigid coupling in robotic joints to belt-driven indexing tables, offering engineers broad flexibility in motion control architectures. The motor’s industrial-grade construction and precise feedback characteristics make it an ideal choice for high-speed packaging lines, labeling machines, conveyor systems, and other process-critical installations.
