Product Description:

The LSM34N-29-602-E2-2KA is a Kollmorgen servo motor from the LSM Brushless Servo Motors series. It converts electrical energy into controlled rotation for axes that require accurate positioning and speed regulation in automated packaging lines, pick-and-place modules, and indexing tables. By integrating the rotor, stator, and feedback elements in a single housing, it provides a compact drive source that simplifies machine integration. The motor is well suited for applications that require rapid starts, stops, and repeatable settling during each operating cycle.

At rated conditions, the motor delivers 3.3 Nm of continuous torque, allowing it to support moving loads during 100% duty cycles without overheating. When rapid acceleration or shock loads occur, the electromagnetic stack can generate up to 13.2 Nm of peak torque for brief intervals. These torque levels are supported by a stall current of 8.3 A peak, which is the maximum winding current that can be applied while the shaft remains locked. During dynamic transients, the drive may reach 33 A peak, so the associated amplifier must provide adequate current headroom. With a torque constant of 0.40 Nm/A, each additional ampere of phase current produces a predictable rise in torque, which helps support stable control response.

Electrical behavior includes a 49 V/kRPM voltage constant that links back EMF to speed and helps with winding supply selection. The windings have 12.4 mH of phase-to-phase inductance and 1.32 Ω of resistance at 25 °C, values that affect current ripple and thermal loss. The motor has 8 rotor poles, which support smooth low-speed motion while maintaining high torque density through the keyed shaft interface. Position data is transmitted through a 17-pin feedback connector from a 2000-line incremental encoder, allowing fine interpolation in digital drives. A 24 VDC holding brake secures vertical axes whenever power is removed.
