Product Description:
The LSM54-3-602-E1-2KA Brushless servo motor is one of Kollmorgen's widely praised electric motion solutions for industrial automation. Kollmorgen servo motors are ideal for applications that require a wide range of speed and torque ratings, as well as precise control and dependability. The LSM servo motor is designed to deliver consistent performance in demanding motion control systems.
The LSM54-3-602-E1-2KA brushless servo motor has a maximum torque output of 1.32 Nm and can rotate at 6,000 RPM continuously. The torque output is 3 in-lb (0.33 Nm). A 1000-line encoder and a 24-volt DC brake offer precise feedback and holding power to the motor. A motor with eight poles and a 230 VAC voltage class is built. The current parameters show a maximum peak current of 3.8 A and a stall current of 1.0 A. The winding inductance of the servo motor is 57.5 mH, and the resistance between phases is 30.29 Ω at 25°C. This servo motor is capable of operating in temperatures ranging from -20°C to +40°C, with a typical thermal time constant of 20-45 minutes. Its thermal resistance, which is within the range of 0.4 to 0.6 °C/W, enables efficient heat disposal during operation.
The LSM54-3-602-E1-2KA servo motor is equipped with a 1000-line incremental encoder to guarantee that users receive precise position feedback, which is essential for closed-loop control in automation systems. The integrated 24V DC brake ensures secure load holding even when the engine is turned off. The servo motor's structure assures durability over the temperature range, and the thermal resistance and thermal time constant data indicate consistent thermal management over long-term usage. The torque distribution is effective and smooth due to the 8-pole design, inductance, and high winding resistance.
