Product Description:

The LSM34N-10-602-E2-OKA is a brushless servo motor manufactured by Kollmorgen for the LSM Brushless Servo Motors series. Designed for industrial automation, it converts electrical energy into controlled rotary motion for tasks such as gantry positioning, indexing tables, and packaging axes. An integrated 2000-line incremental encoder provides the feedback necessary for high-resolution position and speed loops. This arrangement allows the motor and drive to maintain accurate response during repeated starts, stops, and directional changes.

At its continuous operating point, the motor delivers 1.1 Nm of torque, meaning it can sustain this load without exceeding thermal limits. During short transients, it withstands up to 4.4 Nm, supporting rapid acceleration and deceleration. The rotor can reach 6000 rpm, allowing high shaft speed when the motor is coupled directly to the load. A torque constant of 0.37 Nm/A links commanded phase current to produced torque, which helps the drive respond predictably to changing load demand. The windings are optimized for a DC bus derived from 230 VAC, helping the motor operate with the intended electrical match. The motor also has a 0.5 in keyway shaft and an overall body length of 118 mm from the mounting face, which supports direct coupling to common machine elements and compact axis layouts.

A rotor inertia of 0.000022 kg·m² helps reduce the energy needed for speed reversals, which is useful on axes that change direction frequently. The square mounting face measures 85 mm across, allowing direct attachment to NEMA 34 brackets without an adapter plate. The electrical time constant is affected by a winding inductance of 23.8 mH, which helps moderate current rise during sharp command changes. With an assembled mass of 2.3 kg, the motor can be mounted on moving gantries without adding excessive payload. Its combination of moderate weight, compact mounting format, and encoder feedback makes it suitable for responsive motion systems that require stable speed control and repeatable positioning.
