LSM165-173-304-E2-2KA by Kollmorgen

The LSM165-173-304-E2-2KA is a high-performance brushless servo motor from Kollmorgen's LSM Brushless Servo Motors series, combining precision engineering with robust industrial design. This unit delivers a peak torque of 75 Nm (664 In-lb) and a continuous torque of 19.5 Nm (173 In-lb) at a rated speed of 3000 rpm, making it ideal for demanding automation tasks. Its winding resistance (phase-to-phase at 25°C) of 0.98 Ohm and voltage constant of 156 V/kRPM ensure efficient power conversion and stable performance under variable loads. The compact form factor, with a flange diameter of 165 mm and an overall length of 388 mm, simplifies system integration and saves valuable space on the factory floor.

With advanced electrical characteristics, the LSM165-173-304-E2-2KA excels in dynamic motion control. The motor's stator winding inductance of 9.6 mH and a stall current rating of 16.5 A peak enable rapid acceleration and precise deceleration, while a maximum current of 72.1 A peak supports short bursts of high-power operation. The built-in rotor moment of inertia of 0.00128 kg·m² (0.0113 lb·in·s²) (or 0.00163 kg·m² with brake) contributes to low overall inertia, further enhancing responsiveness. With an integrated motor model LSM165-173-304 designation and rigorous quality control, this servo motor maintains consistent performance even under stringent cycle requirements.

Operational reliability is reinforced by a rugged metallic housing and a shaft constructed from ST-60 steel, capable of supporting substantial radial loads. The motor net weight of 18.7 kg (41.2 lb) (or 21 kg (46.3 lb) with brake) balances solidity with manageable mass for automated handling. A dedicated temperature sensor embedded in the winding enables real-time thermal monitoring and intelligent shutdown in overload scenarios, prolonging service life and reducing maintenance needs. The brushless design, coupled with high-energy neodymium magnets, results in low electromagnetic interference and minimal maintenance, driving down total cost of ownership.

Engineered for seamless integration, the LSM165-173-304-E2-2KA interfaces effortlessly with industrial drives and motion controllers, offering configurable feedback options for precision indexing. Its standard flange and shaft dimensions accommodate direct mounting of pinions, belt pulleys, and encoders without additional adapters. Typical applications include punch presses, material feeding systems, high-duty transfer lines, and other continuous-duty automation tasks. With its blend of high torque density, efficient thermal management, and robust construction, this Kollmorgen servo motor is well suited to the most rigorous industrial environments.
