LSM215-589-204-S-0KA by Kollmorgen

The Kollmorgen LSM215-589-204-S-0KA is a high-performance industrial servo motor in the LSM Brushless Servo Motors series, designed by Kollmorgen for demanding automation tasks. Its robust construction delivers a continuous torque capacity of up to 66 Nm, making it suitable for heavy-duty machinery and precise motion control applications. Weighing 45.5 kg in its base configuration, the LSM215-589-204-S-0KA combines substantial power output with a compact footprint for flexible mounting options. Featuring eight poles, the motor ensures smooth, disturbance-free operation across a wide speed range. Peak torque capabilities of up to 210 Nm enable rapid acceleration and high-load handling in dynamic processes.

Detailed technical parameters underline the motor’s engineering precision. It provides Continuous Torque of 66 Nm (589 In-lb) and a Peak Torque of 210 Nm (1859 In-lb). The torque constant Kt is rated at 1.84 Nm/amp, while the voltage constant Ke reaches 222 V/krpm for accurate speed regulation. Electrical limits include a Maximum Current (peak) of 144.2 Amps and a Stall Current (peak) of 38.9 Amps. The winding assembly offers Winding Inductance (phase-to-phase) of 7.4 mH and Winding Resistance (phase-to-phase At 25 °C) of 0.31 Ohms. Mechanical specifics include Poles: 8, Rotor Moment Of Inertia: 0.0077 kg-m^2 (0.0681 lb-in-s^2), and Rotor Moment Of Inertia With Brake: 0.00856 kg-m^2 (0.0758 lb-in-s^2). The motor’s net mass is Motor Net Weight: 45.5 kg (100.3 lb) and rises to Motor Net Weight With Brake: 48.7 kg (107.4 lb) when a holding brake is installed. The shaft is constructed from Shaft Material: ST-60 Steel to withstand high torsional loads.

Operational capabilities emphasize reliability and precision. The high torque-to-current ratio minimizes power consumption without sacrificing output, enhancing thermal efficiency during continuous operation. With an eight-pole configuration and Ke and Kt constants optimized for linear response, the motor maintains stable speed control under variable loads. Inertia values both with and without brake facilitate smooth start-stop cycles and finer position resolution in closed-loop systems. The robust ST-60 steel shaft and optional brake module ensure fail-safe holding torque and long service life in industrial environments.

System integration is simplified through standard interface compatibility with Kollmorgen servo drives and feedback controllers, allowing rapid deployment in existing automation architectures. The motor’s precise electrical and mechanical characteristics support advanced motion profiles in robotics, CNC machining, and packaging systems. Designed for industrial automation, the LSM215-589-204-S-0KA excels in applications requiring high dynamic performance, repeatable accuracy, and continuous duty cycles. Its durable build and comprehensive spec sheet make it an ideal choice for demanding process control and material handling equipment.
