Product Description:

The H-344-H-0413 is a brushless servo motor produced by Kollmorgen as part of the Silverline Brushless Servo Drives series. In motion systems, it delivers commanded torque and velocity to belts, ball screws, or direct-drive loads. This compact electromechanical unit provides repeatable positioning and speed regulation in automated cells, packaging stations, and light machining centers while allowing the connected controller to regulate motion through a closed feedback loop.

The motor can supply 701 W of continuous mechanical power while drawing a steady current of 11.7 A DC. These ratings indicate how much work the axis can perform without overheating during normal duty cycles. A continuous stall torque of 2.10 N·m keeps loads motionless when the drive holds position, and the rated shaft speed of 4050 rpm suits many medium-inertia transmission ratios used in indexing equipment. Back electromotive force measures 21.3 V peak per krpm, allowing the drive amplifier to predict the generated voltage and adjust current loops for stable operation. The motor has a line inductance of 2.04 mH and a line resistance of 0.360 Ω, which affect current ripple, electrical losses, and compatibility with current-mode drives.

For short bursts, the amplifier may deliver 32.6 A DC, letting the rotor produce a peak torque of 5.26 N·m to accelerate loads quickly during index moves. A rotor inertia of 0.000092 kg·m² helps keep settling times low, so feedback loops can reach commanded positions with minimal overshoot. Thermal behavior has a time constant of 16.2 minutes; this delay between copper heating and frame temperature rise provides capacity for intermittent overloads before temperature sensors reach their shutdown thresholds. The motor also has a maximum line voltage of 250 V RMS, a torque sensitivity of 0.179 N·m per ampere DC, and a thermal resistance of 1.6 °C/W, which support the selection of suitable cabling, drive equipment, and cooling surfaces for continuous service.
