Product Description:
The LSM34N-10-602-E2-0KA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. As a rotary actuator, it converts controlled electrical power into precise shaft motion, allowing automated machinery to position loads, index tooling, or regulate continuous processes without mechanical gearing. Its electrical design supports closed-loop control when paired with a matching drive, making it suitable for packaging lines, electronic assembly stations, and material-handling axes that demand repeatable accuracy.
Rated continuous torque reaches 1.1 Nm, giving the drive a steady output capacity during continuous-duty operation. Speed can be commanded up to 6000 rpm, so the motor accommodates high-throughput moves without overspeeding the rotor magnets. The windings are designed for a 230 VAC power supply, and a 2000-line incremental encoder supplies feedback for fine velocity and position regulation. Electrical behavior is characterized by a torque constant of 0.37 Nm/A and a back-EMF constant of 45 V/kRPM; these parameters allow the drive to calculate current and voltage limits in real time. The phase inductance of 23.8 mH and line-to-line resistance of 4.0 Ω influence current response, ripple, and thermal loading. A 0.5-inch shaft diameter simplifies coupling to standard pulleys or gears, and the stator housing extends 118 mm from the mounting face, leaving space for cable routing.
For dynamic events such as acceleration and shock loads, the motor delivers a peak torque of 4.4 Nm. This transient capability works with a rotor inertia of 0.000022 kg·m² to balance responsiveness against overshoot in servo loops. The motor has a total mass of 2.3 kg, reducing the moving load on linear slides or robot wrists. The output shaft is machined with a keyway to provide positive torque transfer to a compatible coupling. The overall length, including the encoder housing, measures 148.2 mm, enabling compact installation in tight enclosures. This length should be considered when routing the feedback cable and providing rear clearance within the machine frame.
